Foy’s to Blacktail Trail Marathon Kalispell, MT   Jun 21, 2026

The Foy’s to Blacktail Trail Marathon is a 26.2 mile trail race on mostly single track with roughly 5,000 feet of climbing. Open to the first 100 participants to register! The first 2,800 feet of climbing occur in just over 5 miles to the top of Blacktail Mountain. The last 21 miles still include >2000 feet of climbing as you gradually descend the long ridge leading to the finish at Herron Park.

All runners will be eligible for a random give away of cool swag like a pair of running shoes!!

Remember to bring your bear spray. All racers must race with it because there is a real risk of running into wildlife such as bears and/or mountain lions that feel threatened and get aggressive. Even those at the back of the pack need to be aware of startling any of these charismatic megafauna.

This race, along with the FTBT-Herron Half Marathon, 10k, & 5k trail races, are our longest-running annual fundraisers. The money raised from the races goes directly to building and maintaining trails in the 40+ mile FTBT system, including new trails on Emmons Ridge south to Blacktail Mountain. In addition to event fees, our trails thrive largely in part to our dedicated sponsors.
