About Staunton Rocks! Marathon

Staunton Rocks! Marathon is the 42.0km ultra trail at Staunton Rocks! 2025 (Conifer, United States). The race starts on August 23, 2025.

Race strategy

Run hard on the first mountain, but save energy for the second.

  • High point at 2899m. Control your HR at altitude.
  • Start easy and control your HR up to 11.3km.
  • Hold your race pace up to 36.9km, but stay in control.
  • Control your HR on the first climb, then run your race pace, and go all out on the final descent from 36.9km.
  • Start · 0.0km–2.0km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.0km–11.3km · Climb of 505m, high point 2899m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. At altitude your pace drops, and that's fine.
  • Work · 11.3km–36.9km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. At altitude your pace drops, and that's fine.
  • Home · 36.9km–42.5km · Descent of 364m averaging 7%. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end. At altitude your pace drops, and that's fine.
