One of my co workers 'races' charity rides. He doesn't really know about the racing scene but he probably trains harder than anyone I know and is fast as hell. He's 'won' a bunch of these, and actually could probably hang in Cat 1/2 if he knew anything about the scene.

He's a bit older now, in his 50's but he's claimed to have 'won' the Redlands Classic charity ride in 95/96, which is a pretty competitive event.
