Here's the beginning of the Koppenberg Circuit race, 35+4:
This is a classic Boulder race, featuring a 17% dirt hill. Unfortunately, I get taken out 100 yards before the base of the hill, on the first lap. As I was following a teammate up the outside, someone made a very abrupt move for his wheel without checking first to see if anyone was already on it. I kept it upright through the impact, just got knocked sideways a bit, but then he got tangled up in my rear wheel, which abruptly stopped turning (caught skewer QR, or some such). Anyway, this means it's not a very interesting video, but if you're bored, knock yourself out.
