The Gravel Grinder is a gravel road race like nothing you can imagine. This event debuts October 4, 2014 and is limited to 2000 riders. There is 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 have long steep climbs, which will test your mental sanity.
