E250 - UNESCO Trail

Race strategy

Hold a steady pace and save energy for every section.

• 1513m descent. Go easy, save your quads.
• Big early climb with 1.9km gain. Hold your pace, save your legs for later.
• Final 959m descent. Save your legs to go all out on it.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Control your HR on the first mountain, save your quads on the descents until 172km, then run your race pace, and start the final descent from 254km under control, then go all out near the bottom.
• Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.3km–11.3km · Climb of 1454m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
• Work · 11.3km–129km · Descent of 1513m averaging 17%, descent of 1592m averaging 16%, descent of 1682m averaging 15%. Plus 6 more climbs and 3 descents. 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. Running pays off here: run wherever you can. At altitude your pace drops, and that's fine. Hike the steepest pitches.
• Fade · 129km–254km · Descent of 1447m averaging 14%, climb of 1581m, descent of 1020m averaging 17%. Plus 6 more climbs 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. 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. At altitude your pace drops, and that's fine. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 254km–263km · Descent of 959m averaging 11%. 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. Hike the steepest pitches.
