We will be utilizing a chip timing system at this event to record your time at the finish. You will be provided with a timing chip attached to the back side of your race bib. It is important to not crease, or fold the the timing chip to ensure your finish time is read. Results after each lap will be displayed on a screen at the finish line turnaround.
Drop bags will be allowed at the start/finish and at the Coldwater Aid Station for all racers. Drop bags will be returned to the start/finish area at the conclusion of the races.
Aid Station Helpers
We cannot produce these trail runs without the help of our amazing volunteer team. You can even help and run on race day. If you would like to join our volunteer team, we are looking for help with event setup, aid station captains, aid station helpers, timing, photography, videography, social media and event breakdown.

The race courses will be well marked with orange plastic ribbons with black polka dots. Trail junctions and turns will be well marked with colored laminated signs that correspond with your race’s color (4M = Blue, 20K = Green, 20M = Yellow, 52K = Red, 52M = White, 100M = Orange). Please pay attention to these signs at each junction as there are multiple race distances and race courses! In addition, blue & white checkerboard plastic flagging will be hung to designate non-race or “WRONG WAY” trails. All runners are responsible for understanding the layout of the courses. Please familiarize yourself with the course maps on our website prior to race day and/or print a map to bring along with you.
Parking / Start Area
The start/finish line is located at Ramada 9 in the Turf Area. Once you enter the park through the entry station, turn right onto Casey Abbott Drive South just past the Turf Picnic Area. The next left will be Chipotle Way – turn left and park in the Ramada 9 parking area.
Tent sites are available at the Turf Area (Rumble Headquarters) next to the start/finish line for $20 for the weekend (Friday and Saturday nights). You may reserve a camping site with your registration this year. There is a bathroom facility located at the staging area. Purchase Camping Permit
Tent & Cot Rental
We will be renting tents and cots for use by runners again this year. You may reserve a tent and/or cot when you register for the race. The tent will be setup when you arrive, so all you have to do is bring your own sleeping bag (or rent one of ours)! The small tents are 7′x7′ and the large tents are 12′x8′.
