Betong 100M

Race strategy

Hold a steady pace and save energy for every section.

• 556m descent. Go easy, save your quads.
• Steep 54% wall. Control your pace and stay focused.
• The finish is runnable. Save your legs to run it all the way.
• Long race. Control your HR and effort. Early mistakes cost the most.
• Ease into the early runnable section, save your quads on the descents until 79.2km, then run your race pace.
• Start · 0.0km–1.1km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 1.1km–14.1km · Plus 1 more climb. 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.
• Work · 14.1km–53.3km · Descent of 556m averaging 10%, descent of 542m averaging 17%, descent of 636m averaging 15%. Plus 3 more climbs and 1 descent. 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. Hike the steepest pitches.
• Fade · 53.3km–79.2km · Climb of 577m, descent of 728m averaging 16%, descent of 804m averaging 6%. Plus 1 more climb. 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. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 79.2km–107km · 27.5km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.

Quad damage
