About Red Race

Red Race is the 19.0km trail race at Vidra Gradac Trail 2026 (Degurić, Serbia). The race starts on June 14, 2026.

Race strategy

Hold a steady pace and save energy for every section.

  • Start easy and control your HR up to 10.1km.
  • Hold your race pace up to 16.5km, but stay in control.
  • Ease into the early runnable section, then run your race pace, and go all out on the final descent from 16.5km.
  • Start · 0.0km–1.9km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Settle in · 1.9km–10.1km · Plus 1 more climb and 1 descent. 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 · 10.1km–16.5km · Descent of 273m averaging 8%, high point 497m. Plus 2 more climbs. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 16.5km–19.4km · Descent of 233m averaging 8%. Build to the finish: leave whatever you have left out on the course.

Course

By gradient, 32% of the distance is uphill, 40% downhill and 28% flat. The longest climb runs 2.0km at an average 10.9% grade (220m of vertical). The longest descent runs 3.7km at an average 5.4% grade (196m of vertical). The steepest climb averages 31.8% over 0.3km. The steepest descent drops at 18.7% over 1.1km. Surface: 61% trail and 36% smooth. Flat-equivalent effort: 27.8 FlatKM.

Poles

Poles bring little benefit here: only about 2.2km of pole-friendly terrain.

Quad damage

Quad damage risk is low (index 13 of 100): a few descents worth noting, none of them decisive.

  • Ease into the early runnable section, then run your race pace, and go all out on the final descent from 16.5km.
  • 12.1–15.4 km · 273 m D−, -8.3% · 4.0 km ahead → your pace
