Col du Tourmalet

The Col du Tourmalet was first featured in the Tour de France in 1910. Since then, it has featured in the race over 73 times and is one of the most prestigious climbs on the Tour.

The early intrepid riders were climbing poor road surfaces on heavy two speed bicycles; in those days, to climb a Pyrenean pass like the Col du Tourmalet was a herculean task. With lightweight bikes and good road surfaces, it is a little easier than for those early pioneers, but it is still 2,100m to ascend.

In the Tour de France, the Col du Tourmalet is often the penultimate climb of the day. It is conveniently situated near many mountain top finishes like Luz Ardiden, Hautacam. There are no shortage of other climbs in this part of the world. One thing always guaranteed with the Col du Tourmalet is that the peleton will be split into little pieces with perhaps twenty or thirty minutes between the front and back of the peleton.


The Col du Tourmalet can be climbed in both directions, and offers a similar gradient and challenge.

East to West (from Lourdes / Luz St Sauvient)

  • Distance – 12.1 miles / 19.4 km
  • Average 7%
  • Max: 10.2%
  • Height gain: 4,560ft / 1390m

It can be hard to know where to start the climb of the Col du Tourmalet. From Lourdes the valley heads slowly up, and as the road gets near Luz St Sauvient it becomes steeper 6-7%. (Luz St Sauvient is also the foot of the climb to Luz Ardiden). The main road leaves Luz St Sauvient and begins it’s remorseless climb to the top with its 7% average gradient. On the lower slopes there are not too many hairpins – just long straights of ascent. As you pass through the last little village Bareges, the gradient increases to 9-10%. There is then a brief respite with one km at just 5.5%. Make the most of this respite because the last half of the climb is an unrelenting 8-9% all the way to the top.  There are now several hairpins to negotiate and you will start to see the road snake above you. The last km of the climb is the steepest at 10.2%

The altitude at the summit is 2,100m and the weather can be very variable. The first time I climbed Col du Tourmalet, the temperature got down to 3 degrees and within 15 minutes the sky changed colour several times. It’s hard to believe, but many photos on here are all within a few minutes of each other.

What was it like to ride?

I’ve been wanting to ride Alpine style climbs for years; the closest I’ve come is Great Dun Fell in the Pennines (700m), but even that can’t really prepare you for the Col Du Tourmalet (2,100m)

The over-riding emotions of the climb is that it is ‘unending’, ‘unrelenting’ There is no real chance for recovery like you might get in a usual ride. It feels like you’re riding fixed and if you stop your cadence, you can ground to a slow speed very soon.

11km to go. Next km at 8%

When riding these climbs, you’re always conscious that your treading a fine line. Go a little too hard, and you cross a threshold of tolerance – which will make the last kms really tough. If you ease back for a km, you feel a little more energy and you become tempted to lift the pace again. The smallest variations in speed can have a big impact on the state of your legs. Riding the Tourmalet, I understood better why pacing is so critical in mountain stages.

There is a real exhilaration in this continuous climbing. When the climb is going well, there is a great sense of rhythm; you’re just going up hill and the altitude meter is getting higher and higher.

At other times, you may feel exhausted and then you look up and see the towering mountain roads above you that still need to be climbed – this can be a tough one for the mind.

The first day I rode I was aware it would be very cold at the top, so wore several thermal layers, this became quite hot and sweaty on the way up, which made it a little uncomfortable. Because it was my first climb, I took it at a very good rhythm, but with always just a little bit in the tank, which was a good feeling.


One reason I came to Pyranees, is that some friends were doing the Sri Chinmoy Oneness-Home Peace Run from Portugal to France. On Saturday they were running up the last half of Col du Tourmalet, I fortuitously caught them 2 kms from the summit, so I got in a few photos. (Most photos on this page are from Peace Run photographers. Many Thanks.) When we set off, the Tourmalet was said to be closed, so we didn’t expect to get to the top but, as we were climbing, the snow gendarmes opened the road. I must admit, in those conditions, it was great to be climbing the mountain with others. The weather up there can be so variable and challenging.


There was a moment when the sun burst through the heavy fog and clouds – it was one of those magic moments, which you can get in this part of the world.


I think I did that ascent in about 1 hour five minutes. I managed to loose my gps file, but to be honest I didn’t mind at all. The beauty of climbing the Col du Tourmalet on that particular day was enough.

Still, the next day I was back, but this time wanted to try race it (if that is the right word for climbing the Tourmalet). I assumed it would be somewhere in the region of one hour, which is a very rough approximation to a 25 mile time trial. I don’t have a power meter on my road bike, but just rode on feel. The first half was great. I kept a good average speed and you start to think – maybe this isn’t so bad after all. But, the last half of the climb felt like I was uncomfortably close to that invisible red line of tolerance. I again wore too many clothes for the ascent – so was carrying some sweaty thermal tops that added to sense of fatigue. A few times, I just had to knock off the speed by 0.5mph to make sure I didn’t blow up. At 1,500m – you’ve still got 500m to climb, which is a daunting prospect

In the end I climbed (19km) from Luz St Sauvent to the top in 1.02.30. An average speed of 18km/h (12 mph). Without sweaty thermal tops and spare 1 litre of water, I might be able to creep under an hour – it does entice you back to have another go.

After the ascent – I descended 20km down the other side. The other side is not as attractive – there is a sprawling ski station, which doesn’t sit too well in the Pyrenean landscape.

In England – you enjoy all of the very brief descents, but I’ve never descended something like that 20km – I wondered if it was ever going to end. It’s actually really hard work on the shoulders – braking and holding on. Still it was fun in it’s own way.

Tourmalet East to West (Saint Marie de Campagn)

  • Distance 10.9 miles /17.5 km
  • 7%
  • Height gain: 4,121ft – 1256m

At the bottom of the descent I did a u-turn and went back up the Easterly approach. I think this side is raced more often. The first kms are quite gentle (5-6%). But, then the last 12km are remorseless – that very challenging Pyrenean gradient of 8-10%.

One thing they have done is put km signs on the road- telling you how far to go, and the average gradient of the next km. What this made me realise is how much of a difference there is between riding an average gradient of 6.5% and a gradient of 8 or 9%. It may sound counter-intuitive, but in the Pyranees, you can see a 6% gradient and think – a good opportunity for recovery!

It is one thing to ride a mountain pass when you’re fresh. It’s another thing to ride the Col du Tourmalet after 50 miles and 2,000m of climbing already. This second climb was a completely different kettle of fish. There was no sense of trying to ‘race’ the climb – it’s more survival  mode. What rhythm and cadence can I maintain?

In England I’m often left thinking – I wish this hill was longer and steeper. In the Pyrenees – you never think this! I was really counting down the km markers – with an increasing exasperation that they seemed slower to appear. The last 7 km from the ski station is a real toil as you grind away.

On the way up from the West, I was imagining what it might be like to ride in the front of the peleton. On the way from the East I was empathising with the ‘auto bus’ – those riders just concerned with making the time limit.

I did the 17.5 km climb in 1.06. An average speed of 9.8mph (16.7 km/h)- still quite respectable for the climb.

Near the top, I saw the weather station which offers another 200m and another challenging climb. It seemed a shame to go all the way to the Pyrenees and not do this last little bit. But, I was really exhausted, and a bit dehydrated. Fortunately, I met a group of riders from Surrey who had two support vans (that’s the way to do the Pyranees), I asked for a bit of water and got some energy powder too. I was very grateful.

After descending the Tourmalet, I still had to go back to Garvanie. I didn’t think of it as a climb. But, actually it goes up 700m to a height of 1,388m at an average of 4%. This is still more climbing than highest climb in England. The total ride was 82 miles and 3,700m of climbing.


  • The only thing I would do different is not wear so many warm clothes. I still got cold on the descent, because I had accumulated so much sweat on the ascent, I don’t think I was any warmer. The main thing is to put on a jacket on the way down – the wind chill factor is amazing.
  • The sun is very strong in this part of the world. I bought some emergency factor 50 after the descent.
  • May is a risky time to come to the Pyrenees. At this time of the year, the high cols may be closed due to the weather. I was lucky with the weather; a few days earlier and it would have been a wash out. Still on the positive side, May is quite quiet. So quiet – most places were actually closed. Needless to say, you have to be prepared for the elements
  • So that was the Col du Tourmalet. Three times in two days and a real desire to go back and do it again!

  1. Very enjoyable account of your rides Tejvan. Love the picture of you riding with clouds and peaks behind, cycling uphill indeed.

  2. Great post and especially the images. Glad you made it to the big climbs you’ve so often mentioned here. Getting the right layers seems half the battle. Oh and the climbing too!

  3. Pingback: Luz Ardiden -
  4. Like you Tejvan, “I’ve been wanting to ride Alpine style climbs for years”. It’s daft that I’ve been cycling for so long but I’ve never ridden the Alps or the Pyrenees – in the summer I always seem to be racing, or preparing for the next race 🙁 Maybe 2016 for me!

    Great photos, and the Luz Ardiden blog is great too, thanks for sharing.
