Our most popular event by far, the Dirty 30 will test even the most seasoned rider.  If Ivan the Terrible doesn't put the hurt on you, we need to come up with a more challenging hill!

The Dirty 30 follows the Unclean 16 course, through serene and peaceful farmland, with 14 miles of added gravelicous ups, downs and flats that will take your breath away.

The Dirty 30 is part of the Michigan Gravel Race Series (MGRS) and designated as the Short Course.  Tandems are only eligible for prizes if they race in the Dirty 30.
