DNF and a Crash

The day before my race, we went out and drove the course. We went pass a turn that was about 75 degrees, and I made the comment someone gonna crash there.

Day goes on, eat some pasta and sleep

Get up at 5 and have this weird feeling

Swim goes accordingly, and I make it out to the bike.
T1 went ok, and now I was off, and cranking it, I was making my way up to the front packs, and was about to take 19&under. At the 10 mile marker, my calf cramps up, at the weird really really sharp turn. My calf starts spasming so I pulled off into the gravel, which is unridable in.

I stand there for 15 seconds, and a guy comes by, takes the turn to sharp, and just flips over and rolls, while still clipped in. He gets up but both tires are out, but he gets back and going.

My calf was still throbbing so I stayed back, but If I would have been 20 seconds back, I would have hit him while he was on the road and wrecked. Im still freaking out from seeing the guy fly through the air like that.
