Dirty 30

Tweet

The Dirty 30 gravel bike race courses consists of almost 90% gravel roads, the largest percentage of gravel compared to other gravel grinder bike races in West Michigan.

The distance of the long course is 50 miles. The shorter courses are 30 and 16 miles. The 30 mile course is considered the short course for the MGRS.

The Dirty 30 events will start and finish in downtown Saranac, just a short jaunt from Grand Rapids, MI. The first half of the course heads east into the open farm country, offering a combination of gently rolling hills and pancake flat gravel roads. The second half of the course brings you west into a hillier and more forested section of the course.
