Well, inside the last three km, he goes down, he doesn't lose time, but it was a real "I owe it to you" moment. I had read something about how Cav and Wiggo had had a falling out after the last Olympics when they did poorly in their Olympic event after being defeindg world champs. Apparently, the Brit Olympic team was focused on pursuit, and the pursuit gold round was the day before the Madison and did not allow Wiggo to recover.
I wonder if it'll be Froome in a break away rather than Cav in a sprint for the road race gold?
