We would like to thank the Byron Forest Preserve for allowing us to hold this event here. It is a beautiful location and it will be a fun weekend with friends on the trails!

We will start the clock every hour, you have one hour to finish that loop. If you don’t finish the loop in one hour you are ELIMINATED! Make sure your last loop is your FASTEST! We determine winners by who runs the final loop the FASTEST!

Choose your distance: 4 hours & 16.6 miles, 8 hours & 33.3 miles, 12 hours & 50 miles.
4.18-mile loop with 361 ft elevation gain
