100k loop through the greater Don Valley, the route has almost no repeat sections.

Consists mostly of singletrack with some sections of paved/gravel paths and a few tiny road sections.

Good luck to those who attempt to conquer this beast of a ride. Big Grin

**Most of it can be ridden either direction except for a couple of trails in the don that are one way only.
