He laughed!

Think this guy was laughing as he went down.

The guy following him had a bit of a brown trouser moment though.

What happened was the lead guy cornered so hard, he caught what must be a stirrup on the ground, that dug in, and he went round in circles. The guy was actually going uphill at the time.

He simply laughed it off, as you should. Thought it was hysterical. Picked up his bike and off he went again.
