About MUT Marathon

MUT Marathon is the 43.0km trail race at MUT - Mountain Ultra Trail by UTMB 2026 (George, South Africa). The race starts on May 30, 2026.

Race strategy

Hold a steady pace and save energy for every section.

  • Start easy and control your HR up to 13.3km.
  • 310m descent. Go easy, save your quads.
  • Hold your race pace up to 23.4km, but stay in control.
  • Ease into the early runnable section, save your quads on the descents until 31.5km, then run your race pace, and go all out on the final descent from 35.3km.
  • 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–13.3km · Climb of 700m. 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 · 13.3km–23.4km · Descent of 310m averaging 12%, high point 985m. Plus 1 more climb. 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 · 23.4km–35.3km · Descent of 714m averaging 9%. Plus 1 more climb. 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. Your heart rate drifts down on its own: don't chase your early-race numbers, go by feel.
  • Home · 35.3km–42.6km · Descent of 466m 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.
