With thousands of runners participating each year, the event supports local charities and scholarships through donations collected during registration.

The course venue starts at Sanborn County Park, where half marathon and 10K runners will ascend to breathtaking peaks offering stunning views. All distances include single-track trails that are both challenging and rewarding. Runners can expect a mix of uphill climbs and downhill sections; experienced trail runners enjoy the adventure while newcomers discover the beauty in walking the hills.
The race starts at various times, with half marathon participants beginning their journey at 7:30 am for the Hiker Division, followed by the 10K run starting at 8:45 am. The main event kicks off promptly at 9:00 am with the 5K runners. Each distance includes its own unique features and challenges.
Weather conditions on race day are expected to be mild but slightly damp with an average rainfall of just under 3.6mm, ensuring a comfortable run despite any occasional drizzle. The UV index is low at 2.0, indicating minimal sun exposure risk throughout the event.
The distances offered include the Half Marathon covering 21km, the 10K running 10km, and the 5K completing 5km. There's also a Hiker Division for those planning to take more than three hours to complete the half marathon.
