Moab's Red Hot Ultra 50 Mile

Race strategy

Run easy on the first mountain, then go all out on the second.

• 298m descent. Go easy, save your quads.
• The finish is runnable. Save your legs to run it all the way.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Ease into the early runnable section, save your quads on the descents until 39.8km, then run your race pace.
• Start · 0.0km–1.8km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.8km–18.3km · Climb of 259m, high point 1748m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
• Work · 18.3km–48.8km · Descent of 298m averaging 7%. This is where the race is built: steady, solid effort. This descent is hard on the legs: short steps, stay in control, poles if you have them. Running pays off here: run wherever you can.
• Fade · 48.8km–75.0km · Plus 1 more climb and 1 descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 75.0km–85.8km · 10.7km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.

Quad damage

Quad damage risk is moderate (index 24 of 100), with 49% of the load in the first half: 1 descent deserves a plan and a couple of downhill sessions before race day.

• Ease into the early runnable section, save your quads on the descents until 39.8km, then run your race pace.
• #1 · 35.8–39.8 km · 298 m D−, -7.4% · 46.0 km ahead → control
• 71.0–75.0 km · 302 m D−, -7.5% · 10.7 km ahead → your pace
