Trail 25K

Race strategy

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

• Steep 31% wall. Control your pace and stay focused.
• 722m descent. Go easy, save your quads.
• Ease into the early runnable section, save your quads on the descents until 16.2km, then run your race pace, and go all out on the final descent from 17.3km.
• Start · 0.0km–2.5km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 2.5km–11.2km · Climb of 872m, high point 1326m. 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. Hike the steepest pitches.
• Work · 11.2km–17.3km · Descent of 722m averaging 15%. Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. This descent is hard on the legs: short steps, stay in control, poles if you have them. Hike the steepest pitches.
• Home · 17.3km–25.4km · Descent of 481m averaging 6%. Build to the finish: leave whatever you have left out on the course. Long descent: keep it even and let go only near the end.

Quad damage

Quad damage risk is low (index 18 of 100): a few descents worth noting, none of them decisive.

• Ease into the early runnable section, save your quads on the descents until 16.2km, then run your race pace, and go all out on the final descent from 17.3km.
• #1 · 11.2–16.2 km · 722 m D−, -14.6% · 9.3 km ahead → control
• 17.3–25.4 km · 481 m D−, -5.9% · 0.0 km ahead → even, let go at the end
