About KAT Speed Trail

Race strategy

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

  • Steep 32% wall. Control your pace and stay focused.
  • Final 1506m descent. Save your legs to go all out on it.
  • Control your HR on the first mountain, and start the final descent from 10.7km under control, then go all out near the bottom.
  • Start · 0.0km–1.7km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.7km–10.7km · Climb of 1405m, high point 2100m. 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.
  • Home · 10.7km–24.0km · Descent of 1506m averaging 11%. 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. Hike the steepest pitches.
