In July 2011, a team of amateur cyclists will ride 500 miles down the length of France to Biarritz, and attempt to reach the summit of the Tour de France's most feared mountain.

Setting off from St Malo on July 3rd, the group of riders will start their six day ride through the North towards Bordeaux, travelling up to 90 miles per day until they reach Biarritz in the Bay of Biscay.

Once completed, the final leg of the journey starts at Pau and includes the ascent of the Col du Tourmalet – 17km of climbing at an average of 7%, peaking at an incline of 10.2%.

Many professional riders see this peak in the North of the Pyrenees as the most difficult on the Tour de France. With hundreds of kilometers in the legs of the riders, will they be able to conquer the Col du Tourmalet?
