Race photos. Jeez. Who *really* wants a photo of themselves looking like a wrecked, sweaty mess after a run? Where does it end up? In a draw. Besides, any family member or friend, even another runner, can take the photo. If a race offered that as a momento I'd find something else to run in. The race photos (like those from Marathon Photos and their kin) area always crap - poorly framed, and poorly processed/colour-balanced.
Dave the Ex-Spartan has the best idea.
