🌵 Look How Far We’ve Come – Grandmaster Ultras 2019 → 2026 🌵

From a small, passionate group in our very first year to a thriving desert ultra community — we’re so proud of how this event has grown!

1st photo (2019 – Our very first event):

A small but mighty crew under the pavilion. This is where it all began.

Notable legends: Tor Gudmundsen (who ran his very first 100-miler and set the men’s course record), Gordy Ainsleigh, Ian Maddieson, Catra Corbett, and Ann Trason (not pictured but part of that historic first year).

2nd photo (2026):

Fast forward to year 2026 — a much bigger, vibrant group of 50+ year old ultrarunners ready to take on the Arizona Strip trails together.

What hasn’t changed? The same spirit, the same “Old is Cool” energy, the same love for these rugged desert trails, and the same belief that age is just a number.

Thank you to every single runner, volunteer, crew member, and supporter who has been part of this journey. You’ve helped build something truly special.

Now it’s your turn.

Registration for Grandmaster Ultras 2027 (Feb 26–28) is open and filling up nicely!

🏜️ Calling all Grandmaster 100K Warriors! 🔥

The 100K at Grandmaster Ultras has historically been one of our **lowest-signed distances** — and we want to change that in 2027!

This is the perfect ultra for experienced ultra runners who want a serious endurance test without going full 100 miles. You’ll run **two full 50K loops** (Thelma & Louise Loop + the out-and-back) on rugged ATV trails through stunning high desert terrain — Joshua trees, rocky canyons, breathtaking overlooks (including the iconic Thelma & Louise viewpoint at mile 19 and 50), and epic desert vistas.

- Date: Friday, February 26, 2027 – Start at 7:00 AM PST (8:00 AM MST)
- Cutoff: Generous **48 hours**
- Elevation: ~3,160 ft gain/loss (two loops of ~1,580 ft each)
- Pacers: Allowed after the first lap or when it gets dark (70+ from the start)
- Aid: Well-stocked stations with friendly volunteers

With the brand new **Course Guide** now live (mile-by-mile details, Garmin maps, aid station info), there’s never been a better time to commit.

Registration opens Monday, May 4, 2026 (May the Force be with you! 😂)

If you’ve been thinking about stepping up from the 50K or stepping down from the 100M, the 100K is your race.
