About Skymarathon

Skymarathon is the 46.0km skymarathon at Tara Extreme SkyChallenge 2026 (Rastište, Serbia). The race starts on August 22, 2026 at 07:00 AM. It starts and finishes in Rastište. The time limit is 12 h.

Race strategy

Hold a steady pace and save energy for every section.

  • Big early climb with 1120m gain. Hold your pace, save your legs for later.
  • Steep 33% wall. Control your pace and stay focused.
  • 1030m descent. Go easy, save your quads.
  • Final 703m descent. Save your legs to go all out on it.
  • Control your HR on the first mountain, save your quads on the descents until 23.6km, then run your race pace, and go all out on the final descent from 39.5km.
  • Start · 0.0km–1.3km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.3km–13.2km · Climb of 1124m, high point 1450m, descent of 475m averaging 11%. 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. Hike the steepest pitches.
  • Work · 13.2km–23.6km · Descent of 1030m averaging 11%. 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. Hike the steepest pitches.
  • Fade · 23.6km–39.5km · Climb of 984m. Plus 1 more climb 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 · 39.5km–43.5km · Descent of 703m averaging 18%. 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. Hike the steepest pitches.

The course climbs 3300m+. With 72m/km of climbing, the course is exceptionally steep, with long hiking-grade sections. By gradient, 44% of the distance is uphill, 45% downhill and 11% flat.

Poles

Trekking poles are strongly recommended: about 11.0km of the course is steep enough for them to pay off.

Quad damage

Quad damage risk is moderate (index 39 of 100), with 48% of the load in the first half: 2 descents deserve a plan and a couple of downhill sessions before race day.

  • Control your HR on the first mountain, save your quads on the descents until 23.6km, then run your race pace, and go all out on the final descent from 39.5km.
  • #2 · 8.9–13.2 km · 475 m D−, -11.2% · 30.3 km ahead → control
  • #1 · 14.5–23.6 km · 1030 m D−, -11.3% · 19.9 km ahead → control
  • 32.5–37.6 km · 628 m D−, -12.3% · 5.9 km ahead → your pace
  • 39.5–43.5 km · 703 m D−, -17.6% · 0.0 km ahead → even, let go at the end
