THE MAMMOTH TRAIL RUN 🦣🏜️ A Chronicle of Grit and Wonder!
October 10, 2026 | High Hope Ranch | 3353 County Road 2009 I Glen Rose, Texas 📍
Attention all trailblazers, pioneers, and audacious gentlefolk! 🤠 The Mammoth Trail Run is calling you out to the untamed expanse of High Hope Ranch. We’ve carved out a thousand acres of rugged Texas Hill Country for a true test of your mettle. Gather the herd and prepare for an expedition that’ll leave you with legendary tales to tell. 🌵
A word to the wise: Some areas of the course feature downright STEEP inclines and declines. Trail shoes with heavy traction are highly advised to keep your boots firmly on the trail! 🥾
OFFICIAL UNDERTAKINGS: Whether you're looking for a brisk morning jaunt or a sun-up to sun-down reckoning, choose your challenge:
100K Ultra: For the absolute boldest of the bunch! (26-hour cutoff) 🕰️
50K | 25K | 10K | 5K: Rugged paths for every level of grit. ⛰️

THE BOUNTY: 🏅
👕 Every pioneer who crosses the finish line earns a handsome Finisher's Medal and an OFFICIAL race shirt.

⛺ Plentiful provisions along the route to keep your canteens full and your wagon rolling.
🎶 A post-race hootenanny complete with hearty grub, cold revitalizing tonics, and foot-stomping music!
