awesome vid!!! i hate helmet cam vids but worn in a race like that is about the best use for one. (thankfully you didnt mount it on the ski pointed at your junk like many do. ha)
that was exhausting to watch. my back would be screaming at me after 7 minutes of pinning it in the surf and at the end of the vid the camera would point to the sky when i passed out from exhaustion, hopefully face up.
you (assumed it was you) did pretty well and didnt appear to go down any, but you dont appear to have 4.3 foot speed.
very nice clip.
