Rollercoaster 21

Race strategy

Hold a steady pace and save energy for every section.

• 556m descent. Go easy, save your quads.
• Steep 27% wall. Control your pace and stay focused.
• Final 534m descent. Save your legs to go all out on it.
• Control your HR on the first mountain, save your quads on the way down from it until 6.6km, then run your race pace, and start the final descent from 15.8km under control, then go all out near the bottom.
• Start · 0.0km–1.6km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.6km–11.4km · Climb of 534m, descent of 556m averaging 15%, high point 876m. Plus 1 more climb and 1 descent. Ease in: hold back more than feels necessary. The race is still ahead. 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.
• Work · 11.4km–15.8km · Plus 2 more climbs and 1 descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
• Home · 15.8km–21.6km · Descent of 534m averaging 9%. Build to the finish: leave whatever you have left out on the course. Very long descent: first half under control, then even, let go only near the end.

• Control your HR on the first mountain, save your quads on the way down from it until 6.6km, then run your race pace, and start the final descent from 15.8km under control, then go all out near the bottom.
• #1 · 2.8–6.6 km · 556 m D−, -14.6% · 15.0 km ahead → control
• 15.9–21.6 km · 534 m D−, -9.3% · 0.0 km ahead → even, first half under control, let go at the end
