I played the nice rando veteran and rode with a newbie today on his first ever brevet. 200k in 10:53. Light rain the 2nd half, not too unpleasant. That is not my slowest 200k; I once ushered a friend through his first 200k and we just squeaked under the 13:30 time limit. Evidently I'm a really nice guy.
Strava estimates my average power was 104w; I think that's heavy.
The other newb was quicker and rode away from us.
