All runs will take place on the Switchgrass Mountain Bike Trail at Wilson State Park. The 100 has the most elevation gain and loss of any 100-miler in Kansas! If you’re looking for a challenging course in the “flatlands” you’ve found it. The trail is easy-to-follow, rugged, single-track with very few trees/wooded areas. Beautiful views of Wilson State Park and Wilson Lake are abundant.

 

Start times:

100 miler – 6:00 AM Saturday, 10/31/26
100k – 6:30 AM Saturday, 10/31/26
20 miler & 10K– 7:30 AM Saturday, 10/31/26

Hell Creek 100 Race Logistics

The races consist of 20(ish) mile loops with no repetition. One loop for 20 milers, three loops for 100k runners, five loops for 100 milers, and seven loops for 140 milers. The 10K will take a cutoff and be a shortened version of the loop.

The course is heavily marked with ribbons and wrong-way signs. It is very easy to follow. Getting off course shouldn’t be an issue.

There are restrooms at the start and finish, with porta-potties at Hell Hill aid station. There is no aid station on-course for the 10K.  Runners in the 10K should carry all they need for the (heavy) 10k.  There are hot showers open year-round at the start/finish & Big Bluestem Campground, which is about ¾ mile from the start/finish.

At the aid stations, Proxima C will be the featured electrolyte/carbohydrate drink. There will also be typical aid station items available.

Photographers will be there all day Saturday to capture all the highs and lows.  All pictures are available for FREE to download within 1-2 weeks of the race.
