Mountain Fitness
8-Weeks of Guided Fitness Classes: July 7, 2026 - August 27, 2026.
Built for mountain athletes, backcountry hunters, and anyone with a goal this fall.
Are you looking ahead to a Labor Day hike, an early fall race, or your dream hunt? Or, maybe you know how busy summer gets, and you want to return to balance after July 4th. Mountain Fitness is built for anyone aiming to show up stronger, more mobile, and more prepared—mentally and physically—when the season shifts. As a collaboration between Stonetree and Run to Hunt, this course is led by the legendary Les Mignery. Running July 7 to August 27, you’ll develop real-world endurance, strength, and mobility—so you can move efficiently and stay injury-free—whether you’re hunting or hiking miles in the mountains.

who it’s for
This class is for you if:
You drew that special tag, or you’re prepping for a late season race or mountain adventure
You want to move well, feel strong, and build endurance—in the gym and out on the trail
You’re already active but want structured, seasonal cross-training
You’re motivated by goals, fresh air, and a great group to keep you accountable
We specifically include hunters here, because they’ve got a clear seasonal goal (and we don’t know anyone else offering a class built for that). But, Mountain Fitness is designed to be inclusive, approachable, and effective for anyone with a fall objective, no matter what moves you.
what you’ll gain
Beyond professional instruction, structured time in the gym and out, you should also look forward to:
Total-body strength and trail-ready mobility
Conditioning that supports real-world performance
Improved recovery, injury prevention, and mental grit
A season of support and structure with expert-led programming
Instructors
“If you got it, get it.” - Les Mignery, before his first 50k race. And he did ‘get it’.

Les Mignery
With nearly 30 years of experience in endurance sports, from running & skiing to cross country races and backcountry hunting, Les Mignery brings a rare blend of field-tested grit and science-backed training.
He’s completed over fifteen 100-mile ultra-marathons (including 12 Bighorn 100 finishes), too many 50-milers and 50Ks to count, and has tackled the Bob Marshall Open three times. Les has hunted from Alaska to Mexico—on foot.
Les’s deep experience, Wyoming roots, combined with his degree in sports science, gives him a training perspective that’s tuned for longevity, strength, and performance.
