Ushuaia Trail Race 30K

Race strategy

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

• Steep 31% wall. Control your pace and stay focused.
• Final 901m descent. Save your legs to go all out on it.
• Control your HR on the first climb, then run your race pace, and start the final descent from 24.9km under control, then go all out near the bottom.
• 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–12.3km · Climb of 541m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Hike the steepest pitches.
• Work · 12.3km–24.9km · Climb of 639m, high point 905m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can. Hike the steepest pitches.
• Home · 24.9km–32.7km · Descent of 901m averaging 12%. No heroics: settle back into your own effort and hold it to the line. Very long descent: first half under control, then even, let go only near the end.
