Hi, I wanted to put in a plug for a local event entering its second year. This is a great event run for a great cause. "BC Gravel"--as envisioned by the organizer--is something to behold. Forest roads, dykes, single track...beautiful mountain vistas and some brutal climbs.
If you want a unique challenge, give it a go. This is a gravel ride that will satisfy those from the CX and mountain bike side of things, and give you a satisfying challenge if you've been coasting on your roadie fitness.
