Listen up, Trail Seekers.

Forget the clock. Forget the noise. There is a different kind of time kept out in the limestone breaks of Glen Rose, and it’s calling you back to the dirt.

Welcome to the High Hope Endurance Run—the beating heart and soul of The Mammoth Race movement.

This Memorial Day weekend, we’re gathering at High Hope Ranch for a festival of dust, grit and glory. This isn’t a "race" in the way the city understands it. This is a 1,000-acre cosmic playground of biodynamic soil, cedar-scented air, and the raw, unpolished beauty of the Texas Hill Country.

🏜️ THE JOURNEY

One ranch. Two days of dirt. No ego, just energy. The ranch meets you exactly where you are.
- 200K & 100K: For those looking to lose themselves and find something better.
- 50K & 25K: The rhythm of the ridge. Pure, sustained groove.
- 10K & 5K: A fast, dirty dance with the trails.
🌀 THE EXPERIENCE
- The Land: You’re running through a sanctuary. Respect the land, feel the vibration of the wildlife next door at Fossil Rim, and leave the world behind.
- The Fuel: We don’t just have volunteers; we have a "Mighty Herd." Our aid stations are an oasis of high-fives, real food, and soulful encouragement.
- The Camp: Pitch a tent, kill your phone, and reconnect. The magic happens between the finish line and the stars. Camping is FREE.
- The Flow: We’re cupless and conscious. We leave only footprints; we take only memories and maybe a little bit of ranch dust in our lungs.
🚀 THE COUNTDOWN
- 200K: Open start midnight to 7AM. Saturday ONLY.
- 100K: 7:00AM
- 50K: 7:30AM
- 25K: 8:30AM
- 10K: 9:30AM
- 5K: 10:15AM
What Your Journey Includes:
- Official High Hope Endurance Run T-shirt
- A Super Groovy Finisher Medal
- Ultra Buckles for 100K and 200K Finishers
- Bragging Rights
- FREE Camping and Boondocking (no-hook ups)
- FREE Entrance and Parking
"The trail doesn't ask who you are; it shows you." — The Herd

Stop counting the days and start making the miles count. The dust is waiting to settle on your shoes.

✌🏼Peace, Love and Dirt
