Aid Station and Race-Day Notes

The Courses: Runners will start the race with a short, scenic loop on the gravel road before heading up the singletrack trail for approximately 3.6 miles to the aid station at the south end of beautiful Cottonwood Lake. The course is mostly rolling hills with some rocky sections… Watch your footing!

At the aid station, all runners will turn around. 12k runners will return to the start/finish line. 30k runners will head downhill for a ways before being directed back up to the Thunderbolt Mountain trail (just past the aid station). From there, runners will climb to the top of Thunderbolt Mountain to the remnants of an old fire lookout. This 3.3-mile segment climbs approximately 1,000 feet with switchbacks and loose rocks. We recommend refilling a water bottle at the aid station before starting this climb!

When 30k runners reach the peak, they must find the comic book at the old lookout and tear a page out to prove they made it! Enjoy the stunning 360-degree view for a moment before heading back down. They’ll hit the Cottonwood Lake aid station for the third time (but be warned, volunteers will pack it up at 1:00 pm.) Then it’s a quick 3.6 miles downhill to the start/finish line!

If you encounter horses, step off the trail to the downhill side. ALL trail users must yield to horses!


Post-Race Food and Awards:  Relax afterward in this beautiful location and join us for brats and beer from Helena microbreweries. You can take a dip in the creek to cool off, and chips, soda and water will be plentiful. Overall and age-group winners will receive a unique, handmade award.


Directions to Trailhead and Camping Options

Allow 1 hour travel time from Helena and 45 minutes from Butte.

Driving south from Helena or north from Butte on I-15, take Exit 151 (Bernice) and head west toward Boulder River Rd #82. At the fork in the road, turn right (watch for signs) and continue about 6 miles on well-maintained gravel road toward White House Campground. Just across from the entrance to the campground and picnic area, you’ll turn RIGHT onto a narrow Forest Service road and proceed approx. 1.6 miles to the Thunderbolt Creek trailhead. (This segment of road is rough in spots, but regular passenger cars should be able to navigate the bumps.)

*** Parking: DO NOT PARK IN THE TURN-AROUND at the trailhead. Horse trailers need room to pull all the way through.  You will be directed to park in the grassy area, side-by-side as tightly as possible. Invite your friends and carpool if possible! Thanks for your cooperation. ***

Camping: Some runners choose to pitch a tent or car-camp near the start/finish. Be prepared for chilly overnight temps in these mountains!
