This is my handlebar cam footage of my Iceman Cometh 2011 race (http://www.iceman.com) which is a 30ish mile point-to-point cross country mountain biking event from Kalkaska to Traverse City, Michigan.
I started my race in Wave 6 at approximately 9:15 am and spent the next 2hrs 1min 14secs pedaling like mad for the finish line, almost crashing when I ran over a stump at 00:06:40 into the video. It was about mile 15 that the leg cramps came, but I was able to continue on without a full fledged lock-up.
What a beautiful day to race, what a fun course to ride, and what an amazing event this years Iceman has turned out to be. I already can't wait for next year!
