50K Run

Want to experience the Dirty 30 bike route at a slower pace? With just one slight mileage tweak to the Dirty 30 cycling route, you can now RUN a 50K at the Dirty 30 Gravel.

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.

  • All 50K runners are required to wear reflective clothing. A headlamp turned on is required while it is dark. There is no harm in being told ‘I see you baby!’
  • Please run on the left side of the road (against vehicular traffic) for the whole 50K so you are aware of approaching traffic.
  • The 50K run cutoff is 4 PM
  • Refueling station at 9ish miles, mile 18 and mile 26
