The blogger whose post I grabbed this from comments,
The Valparaiso Cerro Abajo Race is a legendary urban bike race and is more extreme than skydiving out of an exploding F-18 piloted by Charlie Sheen - while chugging a 2 liter of Mountain Dew.
I think I feel sick!
But I decided to "run" it again. This time from a chaser cam. You want to see what these guys wear in the way of safety equipment? I wonder how many people are permanently injured every year?
