About UTFS 10K

UTFS 10K is the 12.5km trail race at Ultra-Trail du Fjord du Saguenay 2026 (L'Anse-Saint-Jean, Canada). The race starts on August 9, 2026 at 08:00 AM.

Race strategy

Run hard on the first mountain, but save energy for the second.

  • Start easy and control your HR up to the aid station at 7.1km.
  • Hold your race pace up to 7.8km, but stay in control.
  • Final 444m descent. Save your legs to go all out on it.
  • Control your HR on the first mountain, then run your race pace, and go all out on the final descent from 7.8km.
  • 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–6.8km · Climb of 501m, high point 650m. Plus 1 more descent. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace.
  • Work · 6.8km–7.8km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 7.8km–12.2km · Descent of 444m averaging 10%. Build to the finish: leave whatever you have left out on the course. Long descent: keep it even and let go only near the end.
