Raramuri 100M

Race strategy

Hold a steady pace and save energy for every section.

• Big early climb with 1.6km gain. Hold your pace, save your legs for later.
• 1758m descent. Go easy, save your quads.
• Steep 26% wall. Control your pace and stay focused.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Control your HR on the first climb, save your quads on the descents until 67.4km, then run your race pace.
• Start · 0.0km–1.5km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.5km–21.9km · Climb of 1568m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
• Work · 21.9km–79.1km · Descent of 443m averaging 7%, descent of 1758m averaging 8%. 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 · 79.1km–148km · Climb of 1360m, 9.1km of runnable trail, high point 2361m. Plus 1 more climb and 3 descents. 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. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 148km–154km · Climb of 589m. No heroics: settle back into your own effort and hold it to the line. Climb by heart rate or breathing, not pace.

Poles

Quad damage

Quad damage risk is high (index 58 of 100), with 52% of the load in the first half: 2 critical descents, the last of them run on already damaged legs. Downhill-specific preparation and a controlled early pace pay off here.
