About Staunton Rocks! Half Marathon

Staunton Rocks! Half Marathon is the 21.0km trail race at Staunton Rocks! 2025 (Conifer, United States). The race starts on August 23, 2025.

Race strategy

Run the climb at race pace, build your speed on the downhill, and go all out at the finish.

  • High point at 2899m. Control your HR at altitude.
  • Final 355m descent. Save your legs to go all out on it.
  • Control your HR on the first climb, then run your race pace, and go all out on the final descent from 14.6km.
  • Start · 0.0km–2.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.6km–7.8km · Climb of 429m, 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 · 7.8km–14.6km · This is where the race is built: steady, solid effort. Running pays off here: run wherever you can. At altitude your pace drops, and that's fine.
  • Home · 14.6km–21.0km · Descent of 355m averaging 5%. Build to the finish: leave whatever you have left out on the course. At altitude your pace drops, and that's fine.
