I've just tried the really really long triathlon event in GTAV (the one near Trevor's initial safehouse) and killed a spectator at the last checkpoint so I forfeited the mission and it finished with me still wearing my red & white triathlon onesie. When I go home to change my clothes I don't seem to have the onesie available, does that mean if I change outfit I'll lose it?
I'd quite like to keep it, it looks suitably crazy for Trevor!

Yes you'll lose it. You have to fully complete the triathlon in order to unlock the onesie permanently. For now just run around until the next race.
