Description

A hundred yards or so from the gate at the top of Mars Hill urban trail is a not-very-obviously-marked turnoff heading north. From that turnoff head mostly flat and downhill to the urban trail just south of Cheshire. The trail is fast and fairly smooth with a few rocky sections to keep it interesting.

Nice quick ride. Moderately easy up hill so I don't hate myself by the top. Flowy downhill starting at juncture of trails that's a bit rocky but fu… 6.6mi — 0h 45m
