Marathon participants may find RunKeeper helpful, especially its Live component where their progress can be shared with people who can't make it to the race to cheer them on. Of course, RunKeeper also has all kinds of usefulness for those of us (like myself) who are into fitness or inspired by the runners. Connect it with the EarndIt tool to collect points and real-world rewards, and you're on your way to the ultimate in geeky motivation for the gym.
