About Whalers Great Route Ultra-Trail®

Whalers Great Route Ultra-Trail® is the 101km ultra trail at Ultra Blue Island 2026 (Portugal). The race starts on May 1, 2026 at 10:00 PM.

Race strategy

Hold a steady pace and save energy for every section.

  • 1421m descent. Go easy, save your quads.
  • Steep 28% wall. Control your pace and stay focused.
  • Long race. Control your HR and effort. Early mistakes cost the most.
  • Ease into the early runnable section, save your quads on the descents until 57.4km, then run your race pace, and go all out on the final descent from 92.7km.
  • 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–13.6km · Climb of 907m. Ease in: hold back more than feels necessary. The race is still ahead. Climb by heart rate or breathing, not pace. Running pays off here: run wherever you can.
  • Work · 13.6km–50.8km · Descent of 1421m averaging 7%, high point 1018m. Plus 2 more climbs. This is where the race is built: steady, solid effort. 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. Running pays off here: run wherever you can.
  • Fade · 50.8km–92.7km · Descent of 382m averaging 6%, climb of 638m. Plus 1 more climb and 2 descents. Your energy fades, and that's normal: hold a steady effort and stop counting the miles. 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. Running pays off here: run wherever you can. Hike the steepest pitches. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 92.7km–101km · Descent of 474m averaging 6%. No heroics: settle back into your own effort and hold it to the line. Long descent: keep it even and let go only near the end.
