The Michigan Mountain Mayhem (MMM) is a road bike event, and it is a timed challenge ride on the toughest terrain Michigan has to offer.  It will test you both mentally and physically. The MMM is one of the most grueling and challenging rides you will ever participate in. It is always held on the third Saturday of June (June 14th 2025) and is limited to 1,500 riders. 

Nothing compares to the hills of this ride matched up with the early season timing. Four routes to choose from: a 50K teaser, a 100K metric century, a 160K, (100-mile century), and for those who dare… a 200K double metric with almost 10,000 feet of climbing!
