Perpetua Coast 50K

Race strategy

Hold a steady pace and save energy for every section.

• 277m descent. Go easy, save your quads.
• Start easy and control your HR up to the aid station at 17.4km.
• Hold your race pace up to 31.8km, but stay in control.
• Ease into the early runnable section, save your quads on the descents until 26.7km, then run your race pace, and go all out on the final descent from 41.6km.
• Start · 0.0km–2.0km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
• Settle in · 2.0km–17.4km · Descent of 277m averaging 9%. 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. 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.
• Work · 17.4km–31.8km · Descent of 394m averaging 5%, climb of 454m, high point 473m. 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.
• Fade · 31.8km–41.6km · Plus 1 more climb and 1 descent. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. Climb by heart rate or breathing, not pace. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
• Home · 41.6km–48.7km · Descent of 292m averaging 4%. No heroics: settle back into your own effort and hold it to the line.

Poles

Quad damage

Quad damage risk is moderate (index 22 of 100), with 44% of the load in the first half: 2 descents deserve a plan and a couple of downhill sessions before race day.
