About UTFS 55K

UTFS 55K is the 55.4km ultra trail at Ultra-Trail du Fjord du Saguenay 2027 (L'Anse-Saint-Jean, Canada). The race starts on August 7, 2027 at 06:00 AM. It starts in L'Anse-Saint-Jean. The time limit is 14 h.

Race strategy

Hold a steady pace and save energy for every section.

  • 548m descent. Go easy, save your quads.
  • Steep 25% wall. Control your pace and stay focused.
  • The finish is runnable. Save your legs to run it all the way.
  • Control your HR on the first mountain, save your quads on the way down from it until 18.8km, then run your race pace.
  • Start · 0.0km–2.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 2.3km–18.8km · Climb of 684m, high point 569m, descent of 548m averaging 9%. 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.
  • Work · 18.8km–37.5km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
  • Fade · 37.5km–45.4km · Plus 2 more climbs 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. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 45.4km–54.7km · 9.3km of runnable trail. No heroics: settle back into your own effort and hold it to the line. Running pays off here: run wherever you can.
