All was good until I crashed TWICE on the descent of the Col d’Agnes! Oh my God! The first time I misjudged the corner and braked too fast. My back wheel started sliding. But the road was rough like sandpaper and you can imagine what happens when you put sandpaper to rubber! Boom! My tired exploded.
Suddenly I found myself climbing out of the bushes. After that, I tried to actually take it easy. But then my front wheel slid out on another turn and I was down again! Oh man, I just felt so stupid and useless! I was mad! I was mad at myself. I was mad at the world. I was mad!

For the second one it looked like he either hit a slick spot in the road or he was braking too hard. You'll hear a lot of stories about the roads "melting" in the heat at the TDF.
