I did the 50-mile route, but since I live right near the Richmond start and know all those roads so well, I detoured for a little peace and quiet. Nothing like riding with 1500 riders to make me want to escape the madness. So that's why I ended up with five more miles.
The route has changed slightly from two years ago when you did it (I'm sure we passed each other then!) The 50-mile route was not at all an out-and-back so I'm not sure where the century halfway point was.
It was alot of fun, though!
