Summer Cycling in the French Alps

Leysin, Switzerland, August 25, 2013

I started this blog post sitting in the lovely little French town of Guillestre, in the old house being restored by my sister Saakje and her partner Henkka.  Terri and I were there for a few days of vacation before I start work again for an unprecedented 4th consecutive year in one place.  I'm a little surprised myself that I've stayed stationary for so long, but I seem to be having a great time and getting just enough time to travel to keep my wanderlust at bay temporarily.  This is a summary of the bike touring I did this August in France (I finished the big tour on August 15th, then went back down to Guillestre with Terri and came back to Leysin on the 21st; the blog post was finished once I got back to Switzerland.)

So those of you who are faithful readers of my blog know that I love bicycle trips; I've taken at least one long bike trip every year since 2000 except for in 2008 and 2012.  However, this summer, having done my bike trip through Iceland with Terri in June, I decided to try something new in August.  I was in Canada and the US in July, visiting family and friends, but came back to Europe a couple of weeks before school began in order to do a different style of bike trip.  I have always taken camping equipment and ridden with a fully loaded touring bike, allowing me to stop wherever I want, sleep cheaply (or for free) and make the bike trip more of a complete adventure package.  This time, though, I wanted to experience riding the great passes of the Alps, the ones that the Tour de France goes over, travelling as light as possible.  I booked some (not-so-cheap) hotels, got a small back rack trunk to carry a change of clothes, some toiletries, a few spares and a Kindle and set off with my racing bike on the TGV for Avignon on August 6th.  The plan was to spend 9 days cycling back to Switzerland over as many of the great cols as I could.  It was a different sort of travel experience, centred much more on the cycling and less on sightseeing than I am used to.  Here's a summary of what I got up to.

Day 0:  August 6th, Avignon-Carpentras

Distance:                                 36.9 km
Total to Date:                          36.9 km
Final Altitude:                             180 m
Vertical Metres Climbed:            294 m
Time:                                             1:49
Average Speed:                    20.1 km/h
Maximum Speed:                  43.2 km/h

After I got off the TGV in Avignon (man, was it hard to get a booking and a reservation for my bicycle!  It eventually took my sister and two employees of the Swiss railways almost an hour to get it done.). I took a long time and a lot of wrong turns to get out of the city and onto the right road to Carpentras. It was an urban cycling nightmare of one-way streets and misleading signs.  Once I was finally pointed in the right direction, I raced along the road easily, looking up at the white summit of Mont Ventoux all the way to my lodgings above a little restaurant in the pretty old town of Carpentras, a town apparently entirely populated by immigrants from North Africa.  I was awakened repeatedly in the night by thunderstorms of apocalyptic violence.


Day 1:  August 7th, Carpentras-Mont Ventoux (1911 m)-Digne Les Bains

Distance:                                176.5 km
Total to Date:                         213.4 km
Final Altitude:                              615 m
Vertical Metres Climbed:             3312 m
Time:                                            8:59
Average Speed:                      19.7 km/h
Maximum Speed:                    52.8km/h

Happy and tired atop Ventoux!

Of all the iconic climbs of the Tour de France, two loom larger than any others in the public imagination.  One is the climb to Alpe d'Huez, a ski resort near La Grave; I cycled that last October on a weekend jaunt to La Grave with Terri.  The other is the Mont Ventoux, featured regularly in the Tour, including this year when Chris Froome imposed himself on the field with a dominant victory on the climb up the Ventoux.  The mountain is not enormously high (just over 1900 metres in altitude), but since the surrounding countryside is only a couple of hundred metres above sea level, the total altitude gain to the summit is about 1500 metres from Malaucene, one of the three towns from which roads lead right to the barren summit of the highest peak in Provence.
Looking back at the barren summit as I descend the classic route towards Bedoin and Sault

I started the day not knowing whether I would even be able to make the attempt; violent storms the night before were still raging when I woke up, and the proprietor of my hotel was dubious about the wisdom of trying to reach the summit.  Ventoux is named for the violent winds that buffet its upper slopes; last year Terri had the plastic cover blown right off her cycling helmet by gale-force winds near the top of the climb.  I had visions of the same sort of weather hitting me, especially as it was raining on me as I left Carpentras.  By the time I reached Malaucene, however, it was grey but not actually raining, and I set off undeterred.  I rode quickly, trying to race up as quickly as I could.  I passed a few cyclists, but nobody caught up to me until near the end, when a Dutchman about my age came up on me.  We rode together for a while before I had to stop to rest and take a few pictures just as we emerged from the beautiful forested lower slopes onto the barren scree slopes that look like snowcaps when seen from far away.  I took a couple of minutes to myself, then climbed the last few steep kilometres to the summit, emerging into another world right at the top.  Hundreds, if not thousands, of cyclists come up the other way from Bedoin and Sault every day, and I met the horde at the summit.  Somehow I managed to get a picture of me alone with the sign before bundling up into warmer clothes for the descent.  I felt tired and a bit dehydrated, but I was pleased with my time of 1:49 for the 1500 vertical metre climb.  It was the fastest that I would climb until almost the very end of the trip.

Lovely village of Montbrun-les-Bains, just north of Sault
The rest of the day was a long, tiring blur.  I descended at speed towards Bedoin, branching right towards Sault partway down.  I passed the memorial to Tom Simpson, a great British cyclist who died of a heart attack on the Ventoux in 1967, killed by a fatal cocktail of alcohol and amphetamines.  British cyclists leave water bottles, flowers and other mementoes.  I took a photo and kept descending.  In Sault I stopped for disappointing lunch at a restaurant on the main square, and didn't get going until 1:30 pm, with still 100 kilometres to go until my hotel at Digne-les-Bains.  It was a long slog, with a surprising amount of climbing over two smaller passes until I started a long descent that lasted most of 50 km to Digne.  I got in fairly late, around 7:30, with my legs tired and my body crying out for food.  I slept like the dead after a great meal of roast lamb.

Day 2:  August 8th, Digne Les Bains-Col d'Allos (2250 m)-Barcelonette

Distance:                                111.6 km
Total to Date:                         325.0 km
Final Altitude:                            1130 m
Vertical Metres Climbed:             2110 m
Time:                                            5:56
Average Speed:                      18.8 km/h
Maximum Speed:                    58.3 km/h

My second day on the bike was a lot easier than the first, which was good news since I awoke with my legs feeling pretty stiff, tired and leaden after the race up the Ventoux.  Digne intrigued me, since all I knew about the town was that it was the setting of important parts of Les Miserables.  I had forgotten, or perhaps never knew, that one of my favourite Western explorers of Tibet, the redoubtable Frenchwoman Alexandra David-Neel, had lived in Digne and left behind a museum and foundation for religious studies.  I wished that I had time to go poke around the museum. As well, there's an intriguing-looking Valley of the Ammonites, and signs for prehistoric archaeological sites just south of town, all of which I had to leave for another time, if I ever make it back to Digne. I rode out of town after another night of thunderstorms, climbing slightly over two heights of land before joining a river valley that was, as roadside signs proclaimed, part of the route followed by Napoleon Bonaparte in 1815 during his Hundred Days, when he escaped from Elba, took over France and was defeated at Waterloo.  I raced along a valley that seemed to be a monument to forgotten industrial towns and railroads until I turned north towards the Col d'Allos.  I spent several hours toiling up the pretty valley, part of the Mercantour region, until I reached a little ski resort and got serious about climbing.  Late in the afternoon I reached the summit of the Col d'Allos (2250 m), took a few pictures, put on lots of layers for the descent and rode down nearly 30 km of steep, narrow roads across a dramatic landscape of gorges and cliffs before ending up in the pretty tourist town of Barcelonette, where I stayed in Le Grand Hotel, a place adorned with old black and white pictures from the glory days of the Tour de France.  I went to bed tired but full of good pizza, and slept the sleep of the exhausted.

Day 3:  August 9th, Barcelonette-Col de la Cayolle (2326 m)-Col de Valberg (1673 m)-Col de la Couillole (1678 m)-Audon

Distance:                                135.3 km
Total to Date:                         460.3 km
Final Altitude:                            1595 m
Vertical Metres Climbed:             3548 m
Time:                                            8:11
Average Speed:                      16.5 km/h
Maximum Speed:                    55.7 km/h

This was the day that I discovered why professional cyclists dope.  I awoke with my legs absolutely dead, and despite making my way south  again over the incredibly beautiful Col de la Cayolle, my favourite high pass of the trip, in a reasonable 1:57, I was useless for the rest of a long, tough day.  The Cayolle starts with a dramatic gorge, then climbs up an almost deserted valley to the top of a beautiful forested pass.  There's almost no traffic (no trucks, no buses, no campers and only a few cars and motorcycles) and the scenery was suffused with a loveliness enhanced by the first morning of perfect cloudless weather of the trip so far.  It was hard to believe that this pass was a deforested semi-desert 150 years ago before a serious reforestation program rescued it from overgrazing.
The top of the lovely Cayolle

From the top, I rolled south down a beautiful valley (the Var) to the town of Guillaumes, where I turned left and started the second big climb of the day.  This one was only 850 metres in total, but in the heat of the day, on legs that were crying out for EPO, it was a rough climb.  I reached the lovely Col de Valberg and its unlovely ski resort, dropped a few hundred metres to another ski village, Beuil, and then climbed again, very slowly, to the Col de la Couillole before starting a memorable plummet down the red rock gorges (reminiscent of Ladakh) of the Vionene valley to St. Sauveur sur Tinee, past spectacular Roubion perched atop a precipice.  This looks like a classic climbing route, as there's a narrow tunnel and small bridge that keeps the campers, trucks and casual tourists off the road.

Beautiful cliff-top Roubion
At this point, I was physically pretty finished, but I hadn't been able to find accommodation in the valley, I was obliged to turn uphill again and cycle up the Tinee valley for 28 hard-fought kilometres.  An Austrian guy on a bike with a small backpack passed me, and I was fated to keep crossing paths with him for another week.  I made it to the turnoff to Audon, the ski resort where I had found a room for the night, and turned uphill.  It was only 5 kilometres of climbing to Audon, but after 2, I was completely spent.  I stopped, lay beside the road, started again, quit again and generally made an ass of myself until I finally crawled into the ski resort completely dead.  It was the first time in 3 years that I had cracked so totally on a climb.  A beer and a salmon sandwich revived me from the dead, and a subsequent burger and fries completed the rebirth, but I was a sad excuse for a cyclist as I went to bed in my strange little hotel in which I was the only guest.


Day 4:  August 10th, Audon-Cime de la Bonnette (2802 m)-Col de Vars (2109 m)-Guillestre

Distance:                                96.5 km
Total to Date:                         556.8 km
Final Altitude:                            1000 m
Vertical Metres Climbed:             2654 m
Time:                                            6:12
Average Speed:                      15.5 km/h
Maximum Speed:                    59.4 km/h

The little summit loop to the Cime de la Bonnetee (rising diagonally to the left)
This was the day that I realized that I really, truly needed a day off the bike.  I got up early, froze on a frigid descent back to the Tinee valley, had a belated breakfast with the local madmen in front of St. Etienne church, then spent a tough two and a half hours climbing high up over the highest pass so far, the monstrous Col de la Bonnette.  I loved the scenery, with lots of forests and dramatic gorges, but the heavy traffic detracted from the enjoyment, as did my legs, which still seemed to be set on empty.  I reached the top of the col at 2715 metres, then took the steep extra loop that led pointlessly around a little lump on the ridge to make the road reach an altitude of 2802 metres, the highest road in the French Alps (although not in Europe; there are higher roads in Spain and Georgia).  It was a zoo at the top, with campers, motorcycles, cars and bicycles jostling for parking position.

I was glad to snap a photo, put on warmer layers and start the long descent back towards Barcelonette.  I reached the bottom, turned away from Barcelonette and towards the second climb of the day, the Col de Vars.  While I didn't completely crumble as I had the day before on the climb to Audon, I suffered on the steep (10%) grade to the summit, and had to take a long breather a few kilometres from the summit.  I rode much of the last part of the ride with a French guy my age from the Jura who was here on a week's cycling/hiking vacation with his wife.  We had a celebratory beer atop the Col de Vars before I set off through the unpleasant heavy traffic of a French ski resort in the summer.  By the time I reached Guillestre and the shelter of my sister and her boyfriend's house, I had decided to change my plans.  I had originally decided to ride up the second-highest true pass in the French Alps, the Col d'Agnel, the next day, but my slow pace (my average speed had dropped every day since the beginning of the trip) and my real weakness the last two days made me decide to leave the Agnel for later and take a day of slothful indolence instead.

That is one tired-looking cycle tourist!

The view down towards Briancon from the top of the Izoard
After a day devoted to eating, napping, playing guitar and then eating some more, I awoke on Monday morning feeling more human and with my legs greatly revived and less heavy.  I got going at a reasonable hour (around 7:30) and set off immediately climbing up the iconic Tour de France setting of the Col d'Izoard.  The road leads through a flattish section of dramatic gorges along the Guil river before turning uphill to climb through pretty scenery towards the steep summit and its stretch of Ventoux-like desert (La Casse Deserte).  I felt strong and set a good pace, not getting passed by anyone until a young racer and a tough old 60-something rode by me a couple of kilometres from the summit.  I was secretly pleased to see the greybeard catch up to, pass and streak away from the youngster near the summit; the youngster looked crushed by this.  At the summit, I relaxed for a few minutes, took a few pictures, put on warmer layers and set off downhill to Briancon.

Briancon was a nightmare of traffic jams and heat, but once I had escaped I had a fast, pleasant ride up the gentle grades of the Col de Lautaret, the prelude to the famous Galibier.  I kept up a pace of over 20 km/h, which didn't seem that hard at first, but at the top, I definitely felt the lactic acid in my legs.  I had an ice cream, filled up my water bottles and met a couple of fellow Canadian cyclists, Daryl and Pierre, whom I accompanied to the summit.   Daryl was an ex-racer and was quicker than me, but I managed to keep up with Pierre.  Pierre recognized my Butterfield and Robinson bike since his parents used to take holidays with them.  The climb to the summit is absolutely stunning, through wildflower-dotted meadows under reddish cliffs.  It's not too long (8.5 km) or steep (average 7.5%).  It's really from the other side, the long climb over the Col de Telegraphe to the Galibier, that the pass lives up to its fearsome reputation.  I rode partway downhill, had a sandwich and then cruised the rest of the way to the town at the bottom of the Telegraphe, St. Michel de Maurienne.  I was having a celebratory beer by 5 pm, and was asleep by 8:30, happy after a good day in the saddle.

Day 6:  August 13th, St. Michel de Maurienne-Col d'Iseran (2770 m)-Bourg St. Maurice

Distance:                               118.8 km
Total to Date:                         798.4 km
Final Altitude:                             850 m
Vertical Metres Climbed:             2457 m
Time:                                            6:05
Average Speed:                      19.5 km/h
Maximum Speed:                    64.6 km/h

Partway up the final climb to the summit of the Iseran
Although the Iseran is the highest pass in the French Alps, this day was the easiest one of the entire trip in terms of riding.  It took 75 km to get up to the summit, in a series of steep steps followed by long flattish stretches along a river valley that's postcard perfect.  I stopped partway to have a hot chocolate and a pastry, enjoyed the views and, sooner than I had expected, I was at the foot of the steep final wall.  I really enjoyed this part, with dramatic precipices framing oceans of wildflowers, and I arrived at the summit feeling pretty strong.  It was cold and windy at the top, so I didn't linger but raced down the steep road into the sprawling ski resort of Val d'Isere for a beer and a plate of fries.  I made it into Bourg St. Maurice by 5 o'clock and found my hotel, full of gregarious Dutch and German cyclists.  A great meal in an outdoor restaurant and I was asleep by 9, ready for a big ride the next day.

Day 7:  August 14th, Bourg St. Maurice-Cormet de Roseland (1961 m)-Col des Saisies (1657 m)-Col des Aravis (1486 m)-Col de la Colombiere (1613 m)-Samoens

The Aiguille de Glacier seen from the Cormet de Roselend
First pass of the day!

Looking at the elevations of these passes, this day doesn't look that hard; not one of them is over 2000 metres above sea level.  This impression is wrong; it was in fact the hardest day of the entire trip.  Four passes and a final climb into the Samoens valley added up to 3700 vertical metres of climbing and a very tired pair of legs.  The first climb was the highlight of the day, one of the top three passes of the trip (along with the Joux Plane and the Cayolle).  The Roselend was quiet, cool and very pretty.  Almost no traffic disturbed my peace of mind along the narrow road.  At the top, a green jumble of hills tumbled down to a reservoir before tumbling down to the busy tourist town of Beaufort.
Second pass of the day!

From the lake onward, traffic picked in a harsh crescendo that lasted for the next pass and a half.  The climb up the Col des Saisies was unpleasant:  hot and wall-to-wall traffic up to a typical pre-fab concrete ski resort.  I was glad to head down to Flumet, cross the Albertville highway and start climbing up to the Col des Aravis.

Third pass; starting to feel and look tired!
The climb up was pleasant, but my legs were starting to complain.  I had seen the other side of the pass last fall, but the climb was through new territory.

The fourth pass of the day:  a pass too far!
I raced down to Le Grand Bornand, passing graffiti from this year's Tour de France, and then started a rather weary ascent of the Col de la Colombiere, again familiar territory from a trip last fall.  The downhill to Cluses left me more than ready for the end of the day; it was after 6 pm and all I wanted was a meal and a bed.  Instead I had to traverse the rather bleak post-industrial wasteland of Cluses and make a final 300-metre climb over a ridge to gain entry to the Samoens valley.  I was bone-weary, but I managed to fly along the flat valley bottom at 29 km/h and climb up to my hotel, the slightly pretentious Edelweiss.  I wandered down to have dinner only to be told that the restaurant was full and I would have to find dinner elsewhere.  It was a long, tired walk back to the hotel after a huge steak frites dinner.


Day 8:  August 15th, Samoens-Col de Joux Plane (1700 m)-Col de Joux Verte (1760 m)-Pas de Morgins (1369 m)-Leysin (1300 m)

Distance:                                 93.0 km
Total to Date:                       1034.3 km
Final Altitude:                            1280 m
Vertical Metres Climbed:             2848 m
Time:                                            5:53
Average Speed:                      16.0 km/h
Maximum Speed:                    65.3 km/h

One of my favourite passes!
This final day of the trip was a lot of fun, even if I again was starting to feel the effects of four straight days of big climbs.  The Col de Joux Plane was almost traffic-free, steep and pretty.  I managed to make it to the top, a 950-metre climb, in just over an hour of steep climbing (the average grade is 9.5%, making it the steepest pass of the trip).

The Mont Blanc looming large above the Col de Joux Plane
I rolled down into Morzine, a downhill mountain-biking mecca, then turned uphill again and climbed another 900 metres to the Col de Joux Verte, just outside Avoriaz.  From there I descended to the lift station of Les Lindarets and used the ski lifts to get up into the Chatel ski area.  A slightly dodgy walk down along a steep scree slope finally led to pavement and a descent into Chatel.  I turned uphill for 3 easy kilometres to the Pas de Morgins and descended into Switzerland.  In the town of Morgins, I met up with my friend Avery and rode with him back home, first downhill to the Rhone Valley, then uphill to Leysin, my home base.  Despite having lived here for three years, I had never done the complete climb from Aigle before, put off by the heavy traffic.  I climbed up fairly slowly in the heat, and Avery left me behind.  I climbed the last section, from Sepey into Leysin, as slowly as I have ever done.  It was sort of sad that after so much cycling, I was so slow, but I think of the trip as training.  I would be faster afterwards, after my legs recovered, even if I was turtle-like that day.

Addendum:  Four more days in Guillestre!

No sooner was I back in Leysin than I was packing the car with two bicycles to drive right back south to Guillestre with Terri.  Terri had a week off between summer and fall terms and was keen to do some cycling, and Guillestre is perfectly located for that sort of thing.  I think that Bedoin, La Grave, Bourg St. Maurice, Barcelonnette and Guillestre are probably the five absolute epicentres of road cycling in the French mountains.  With the Vars, Agnel and Izoard right out of town, and more passes just a short distance south near Barcelonnette, Terri was excited with the possibilities.

Looking from the top down the last two kilometres of the Col de Izoard
We were in town for four days.  We started with the Izoard, and Terri really enjoyed it, although there was a lot more traffic than there had been a few days before.  I think the Izoard is a good test of climbing ability, with 30 kilometres and 1360 vertical metres, as well as lovely scenery and a great warmup ride through the gorges.  I rode faster than I had the first time (2:11 instead of 2:18, starting in Guillestre) and Terri had a great ride, really enjoying the scenery and the challenge.

The second day was harder, as we rode the Col Agnel, the second-highest pass in France at 2744 metres.  It's a substantially longer ride (42 km) and gains more height (400 m more).  The Agnel leads to the Italian border, and gets quite a lot of motorcycle and bicycle traffic, making it slightly too busy for my taste.  It's a long approach along a valley that seems to climb fairly steadily the whole way until the final few switchbacks.  Both of us were feeling the effects of the Izoard in our legs, and weren't as quick or effortless as the day before.  I made it to the top in 3:05 and shivered at the top in the swirling mist, dodging the tangle of motorcycles, photo-happy tourists and cars infesting the summit.  Terri and I rode back, trying to escape the rain gathering atop the pass and feeling pretty tired.  We decided to have a lazy day the next day, and felt justified when it rained.

On the last day, we drove south to Barcelonnette and rode the Cayolle again.  This was my favourite big pass the previous week, and so I recommended it to Terri.  She absolutely loved it, and conditions could not have been better.  There was almost no traffic, not a cloud marred the sky and the scenery was even better the second time around, with the lower gorges and the larch forests of the upper stretches bathed in mid-day sunshine.  I got up the pass 13 minutes faster than the first time around (1:44 instead of 1:57) and Terri absolutely flew up the pass, feeling stronger and quicker than she had on previous climbs.  It was a great final day.
Triumphant atop the Cayolle
On the way home to Leysin on Wednesday (yesterday), we stopped the car at the Col de Lautaret and rode the last 8.5 km up to the Col de Galibier.  Terri hadn't ridden this last year on a weekend in La Grave, so it was unfinished business.  Starting from the Lautaret, the ride is easy, beautiful and spectacular.  Terri loved it and found it much less daunting than its reputation.  I made it up in 0:49, rather than the 0:57 it took me the week before (after doing the Izoard.)  I was pleased that I was faster on all three climbs that I repeated; maybe all that "training" on the Avignon-Leysin ride paid off.  Or maybe riding on fresher, better rested legs makes a big difference!

At any rate, it feels good to have done so much bike riding up so many great cols in such a concentrated period of time.  I feel fitter than I did before, and I would be curious to see if I've gotten faster on the local rides that I have been doing for the past 3 years.

(A few days later:  I did the climb that I have to do every time I ride back into Leysin, the Sepey-Leysin road, yesterday.  I had had two days off from cycling, I warmed up with a quick flattish ride to Diablerets, and I basically had ideal conditions.  I did in fact climb faster than ever before, 17:10.  My previous record of 17:25 was set last year when I was coming down from six weeks at high altitude, effectively blood-doping me.  My non-altitude record was 17:50, so it's a pretty reasonable improvement in climbing speed.  On the other hand, when the professional riders in the Tour de Romandie came up from Sepey in April, 2011, the winner made that same climb in a bit over 9 minutes, so there's an awfully long way to go to be genuinely fast!)

I'm not sure that I would want to do a bike trip in this style again; although the riding is great, I feel as though it sacrifices too much of the joy of sightseeing that I love in bicycle touring.  The days become just about riding and take away some of the serendipidity and spontaneity of rolling along seeing what's over the next hill.  Like Lance Armstrong said (correct in more ways than one), it's not about the bike.
