6hr/12h/24h

The course is a runnable 2 mile loop on double track dirt road. 170 feet of elevation gain and 8,500 ft over 100 miles is not completely flat but is enough to make it interesting. There will be an aid station at the Softball Field with real food and typical aid station foods. There will be hot foods and real foods such as hot dogs, burgers, veggies burgers, pizza, spaghetti, quesadillas, cups of noodles, bacon, etc. There will also be real non-porta-potty bathrooms. ***NEW 2026 RULE*** Runners in the 6/12/24hr race will have an official result that is limited to the mileage they complete in their given race. This means that runners in the 24hr will no longer be allowed to continue past 24hrs to earn a 100 mile buckle. If you wish to go after a buckle, sign up for the 100 mile race and accept the risk of a DNF if you do not make it. If you sign up for the 24hr you will receive whatever mileage you get within 24hrs, even if it is 98 miles. If you get 100 miles within 24hrs you will get a buckle.

RV/Camping/Parking

RV parking will be allowed at no additional cost but will be limited to 20 spots. Tent camping will be allowed on the softball field and car camping will also be allowed in the dirt parking lot adjacent to the softball field. Half Marathon runners will not be given the option to camp overnight in order to save space for the 24H participants.

They are pretty cheap if you reserve in advance.

100 Mile Race

The 100 mile race will take place on the same 2 mile double track dirt road loop as the fixed time (24h/12h/6h) races. UPDATED TIME CUTOFF: The cutoff will be 32 hours, 3pm Sunday. This is different than previous years where the cutoff was 30 hours. We made this decision due to how much elevation gain the course ended up actually having (8,500ft-9,000ft) ***24hr runners will be expected to stop at 24hrs. They will no longer be allowed to run beyond 24hrs to get a buckle. This is to disallow mid-race changes to your registration which might affect podium standings.*** 100 MILE FINISHERS WILL RECEIVE A BUCKLE***. if you signed up for the 100 mile race and finish under 32 hours, you will get an incredible buckle designed by Corriente Buckle Company. A picture of the buckle can be found on our socials or website The course has approximately 8,500 ft of gain in 100 miles, subtle rolling hills, the elevation graph can be found in the gallery here on Ultrasignup or on the website.

NO MID RACE CHANGES

A new, or rather re-emphasized, rule for 2026 is there will be no mid race changes to a different race other than the one you signed up for. If you signed up for the 100 and want to drop to the 24 you will not be allowed to and will have to accept a DNF if you do not reach 100 miles within cutoff. If you signed up for the 24hr you will not be allowed to upgrade to the 100 at mile 82 or mile 96. Your official result will be your 24hr distance. If you signed up for the 24hr and wish to drop to the 12hr, you will stay in the 24hr and you can just stop running whenever you want. This is to avoid the unnecessary complications and that arise from mid-race race changes such as unfair changes to podiums after the race is over unbeknownst to runners who believed they made podium. You are not allowed to change races after race registration closes.

Non-Profit Organization
