Boyne Mountain – Mountain Mayhem Gravel Grinder – October 3, 2015
The Gravel Grinder will be a gravel road race like nothing you could have imagined.

There will be a 20-mile, a 45-mile, and a 60-mile race. The 20-mile race is very flat, but the 45- and 60-mile races will have long steep climbs, which will test your mental sanity.
