The Assenmacher 100 is a recreational and social fun bicycle ride through the farmland and villages of mid-Michigan. Started in 1980, it has become one of Michigan's premier century rides and has been endorsed by the Governor's Council on Physical Fitness, Health and Sports. It is held each year on the third Sunday in August. With routes of 20, 34, 56, 66, and 100 miles, there are courses for experienced cyclists as well as the casual rider. It has become a popular DALMAC warm up ride. Come on out for a great ride!
