Filthy 50 (50K Run)

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.
Slick 6 (10K Run)
We want to share the Dirty 30 Gravel love and bring runners and cyclists together on race day! Gravel adventures are fantastic on foot!
The Slick 6 Run (10K) will be an out and back course, starting and finishing course by the main start/finish line in downtown Saranac. You’ll be running on some pavement, then onto gravel up Parsonage, continuing south Darby with a final right on Peck Lake. The turnaround will be just before Nash Highway. Runners should run on the left hand side against vehicular traffic. Volunteers will be on hand to assist you.
Stick around after you finish and you can watch the other events start in downtown Saranac. It will be amazing!
