The MMM Gravel Grinder is a gravel road race like nothing you can imagine. This event is limited to 2000 riders.
Expect lots of fast gravel mixed with some tough climbs, multiple sections of tough seasonal roads which have sand, mud and rocks and also a white-knuckle descent. Whatever bike/tire you choose it will be the wrong one at some point. This route will test your mental sanity. The Michigan Mountain Mayhem will be the series finale for the MGRS and awards ceremony will take place after the race.
