LOCATION: Old Shooting Range Trailhead up Davis Gulch, on Helena, Montana’s South Hills Trail System. DESCRIPTION: The course is a modified figure 8 loop on Helena’s South Hills trails (Mount Ascension and Rodney Ridge areas). Each figure 8 is 100% singletrack, 11.57 miles, and 2,645 feet of elevation gain per figure 8.

You’ve got 12 hours to cover as many complete loops as possible.
You don’t have to run all night, one complete figure 8 loop anytime during the 12 hours and you are a finisher.
You don’t have to run continuously. Do one loop, then go sleep somewhere, go dancing, etc., and come back later for another loop.

Even though this event takes place just outside the City of Helena, this is Montana so do not assume that you won’t run into wildlife. Deer, black bear, and mountain lion have been seen along these trails. Also, being Montana trails, there are plenty of rocks out there. It’s a HURL event, we can’t make it easy on you!

RULES: Runners must complete the Mt Ascension loop (clockwise), and then the Rodney Ridge loop (counterclockwise). The Overall and age division winners are determined first by mileage covered, as outlined below, then by time. Runners must complete one full figure 8 to be an official finisher. Each completed figure 8 counts as 11.5 miles, the Mt. Ascension loop counts at 7.5 miles and the Rodney Ridge loop counts as 4 miles. There is no mileage credit for partial loops.On your last time out, you can either complete the Mt. Ascension or Rodney Ridge loop only, rather than the full figure 8, and it will count towards your mileage total. Runners finishing a complete figure 8 after 6:00 a.m. will only be allowed to continue on the Rodney Ridge loop. All full Rodney Ridge loops completed after 6:00 a.m. will count towards your mileage total.

Anyone claiming they have been running but have really been hiding in the porta potty (or found to be cheating in any other way) will be locked in a porta potty and hauled off inside it.
