About UTCT 100 Miler

UTCT 100 Miler is the 163km ultra trail at Ultra-Trail Cape Town 2027 (South Africa). The race starts on November 19, 2027.

Race strategy

Hold a steady pace and save energy for every section.

  • Steep 52% wall. Control your pace and stay focused.
  • 726m descent. Go easy, save your quads.
  • Long race. Control your HR and effort. Early mistakes cost the most.
  • Control your HR on the first climb, save your quads on the descents until 69.8km, then run your race pace, and go all out on the final descent from 153km.
  • 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–15.4km · Plus 1 more climb. 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 · 15.4km–69.8km · Descent of 726m averaging 13%, descent of 659m averaging 11%, descent of 789m averaging 6%. Plus 3 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. Hike the steepest pitches.
  • Fade · 69.8km–153km · Climb of 563m. Plus 1 more climb and 3 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. 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 · 153km–161km · Descent of 422m 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.

Course

The course climbs 7187m+. With 44m/km of climbing, this is a rolling, mostly runnable course. By gradient, 33% of the distance is uphill, 36% downhill and 31% flat. The longest climb runs 6.6km at an average 9.2% grade (615m of vertical). The longest descent runs 12.8km at an average 6.2% grade (789m of vertical). The steepest climb averages 52.2% over 0.8km. The steepest descent drops at 48.0% over 0.2km. Surface: 67% trail, 17% road, 8% smooth, and 5% technical.

Poles

Trekking poles are strongly recommended: about 14.0km of the course is steep enough for them to pay off.

Quad damage

Quad damage risk is high (index 67 of 100), with 57% of the load in the first half: 3 critical descents, the last of them run on already damaged legs. Downhill-specific preparation and a controlled early pace pay off here.

  • Control your HR on the first climb, save your quads on the descents until 69.8km, then run your race pace, and go all out on the final descent from 153km.
  • #1 · 32.7–38.2 km · 726 m D−, -13.0% · 122.3 km ahead → control
  • #2 · 44.5–50.4 km · 659 m D−, -11.1% · 110.1 km ahead → control
  • #3 · 57.0–69.8 km · 789 m D−, -6.2% · 90.7 km ahead → control
  • 93.5–96.5 km · 287 m D−, -9.7% · 64.1 km ahead → your pace
  • 153.1–160.5 km · 422 m D−, -5.7% · 0.0 km ahead → even, let go at the end
  • Plus 2 more notable descents not listed: your pace.
