[SIZE=10.5pt]I have watched triathlon events live and see some triathletes wear their GoPro on their heads. Most of them wear them only in the bike leg, some during the bike and run, but I have not seen people who wear it during the swim. Maybe it would be bothersome to wear when swimming during the breathing. These events I watched are local triathlon contests only so they allow GoPros. They are actually a good thing since it would be awesome to watch their videos during the race and have a perspective of how it is during a triathlon race. [/SIZE]
