I just posted in the endurance forum and noticed this one and thought I give this a shot as well.
So I just got the Garmin Edge #305 and noticed the battery life is 12 hours. I wanted to use this unit during 24hr races. Am I SOL or is there a trick to piggy back or some how extend the battery life so I can record the entire race?
