One of my memories of the 2013 edition was the many folk walking up the first inclines before we had even got to a HC climb. The amount of folk walking just got more and more when we did. When I got to the Alpe Du Huez. There was a voice in the back of my head telling me its OK to stop and stretch (Id done it in a oner the day before). When I did so I had one almighty cramp on the inside of my thigh. Thats the last time I can remember cramping on the bike. I too became a walker for a corner of two until I walked off the cramps
