Last weekend while racing cyclocross I brought along the Go Pro Camera. Originally I had planned to run the chest mount because the point of view would be so much better with all of the obstacles throughout the race, running through barriers, riding over downed telephone poles, muddy switchback hills and of course the PBR drinking stations. After mounting the chest strap up I realized that it interfered with my number plate and I switched back to the handlebar mount. I think I was more worried with what the rather strict officials might say than my number. In hindsight I shouldn't have worried about it since it was a no points, just for fun race.
Anyway I hope you enjoy the video, sorry for the smudge on the lens, I must have gotten it dirty during the pre-ride warmup.
