About UTFS 10K

UTFS 10K is the 12.5km trail race at Ultra-Trail du Fjord du Saguenay 2027 (Mont Édouard, Canada). The race starts on August 8, 2027 at 07:30 AM. It starts in Mont Édouard. The time limit is 7 h.

Race strategy

Short race: go all out.

  • Hold your race pace up to 7.9km, but stay in control.
  • Control your HR on the first mountain, then run your race pace, and go all out on the final descent from 7.9km.
  • Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 1.9km–7.9km · Climb of 498m, high point 650m. Plus 1 more climb and 1 descent. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 7.9km–12.3km · Descent of 445m averaging 10%. Kick for the line: give it everything you've got. Long descent: keep it even and let go only near the end.

Course

The course climbs 667m+. With 53m/km of climbing, this is a true mountain course with sustained climbs and descents. By gradient, 38% of the distance is uphill, 45% downhill and 18% flat.

Quad damage

Quad damage risk is low (index 10 of 100): a few descents worth noting, none of them decisive.

  • Control your HR on the first mountain, then run your race pace, and go all out on the final descent from 7.9km.
