About Legacy Dash 10K

Legacy Dash 10K is the 10.0km trail race at Trail of the Kings Lake Toba by UTMB 2026 (Parapat, Indonesia). The race starts on June 14, 2026.

Race strategy

Short race: go all out.

  • Hold your race pace up to 5.9km, but stay in control.
  • Control your HR on the first mountain, and go all out on the final descent from 5.9km.
  • Start · 0.0km–1.8km · Race-day nerves push your heart rate up: don't follow the crowd, find your own rhythm.
  • Work · 1.8km–5.9km · Plus 1 more climb. This is where the race is built: steady, solid effort. Climb by heart rate or breathing, not pace.
  • Home · 5.9km–10.9km · Descent of 235m averaging 5%, high point 1146m. Kick for the line: give it everything you've got.

The course climbs 230m+. With 23m/km of climbing, the course is predominantly runnable. By gradient, 32% of the distance is uphill, 23% downhill and 45% flat. The longest climb runs 5.9km at an average 4.0% grade (235m of vertical). The longest descent runs 5.0km at an average 4.7% grade (235m of vertical). The steepest descent drops at 8.3% over 2.5km. Surface: 72% road. Flat-equivalent effort: 11.4 FlatKM.

Poles

The course is runnable enough that trekking poles are not needed.

Quad damage

There is too little runnable descent to damage the quads: plan the race around climbing and fuelling.

  • Control your HR on the first mountain, and go all out on the final descent from 5.9km.
