POLJT 2026 · 50K CATEGORY OVERVIEW

50K

The category is named 50K, with an official course distance of 55 KM, around 2,324 m of total ascent and 2,322 m of total descent. This is the longest and most physically demanding category at POLJT, where pacing and nutrition strategy are especially critical.

50K Route Notes and Key Reminders

  1. The opening section is mainly continuous rolling mountain terrain. Keep your rhythm steady and avoid pushing intensity too early.
  2. At around KM 9.5, runners reach CP1 (COT 06:45 AM), an important route-check point. Confirm the 50K course markings again before continuing.
  3. From about KM 15, the course enters a sustained downhill section. Protect your quads, knees, and ankles, and strictly control downhill speed.
  4. At around KM 20, runners arrive at CP2 (COT 08:30 AM), then enter a lower-elevation valley section. The lowest point is approximately at KM 21–22.
  5. After leaving the valley, runners face a long, steep climb. Complete hydration and nutrition at CP2 and avoid over-accelerating before the climb.
  6. At around KM 24, runners pass SP2 (water only), then return to higher elevation and repeated rolling terrain in the second half, requiring ongoing energy management.
  7. Parts of the course between CP2 and CP3 (CP3 at KM 30.5, COT 01:15 PM) have no mobile-phone signal. Check your condition and supplies before entering. In an emergency, remain on the official course and ask race staff or rescue personnel for help.
