About Snowbasin 28K

Race strategy

Run the climb at race pace, build your speed on the downhill, and go all out at the finish.

  • High point at 2617m. Control your HR at altitude.
  • Final 671m descent. Save your legs to go all out on it.
  • Ease into the early runnable section, then run your race pace, and start the final descent from 16.3km 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–5.7km · Ease in: hold back more than feels necessary. The race is still ahead. Running pays off here: run wherever you can.
  • Work · 5.7km–16.3km · Climb of 519m, high point 2617m. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. At altitude your pace drops, and that's fine.
  • Home · 16.3km–27.1km · Descent of 671m averaging 6%. 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. At altitude your pace drops, and that's fine.

  • 16.3–27.1 km · 671 m D−, -6.2% · 0.0 km ahead → even, first half under control, let go at the end
