Course notes

  • gear With trail terrain, choose a shoe with moderate cushioning for optimal performance.
  • nutrition For 100km+ efforts, prioritize real food at aid stations to prevent palate fatigue.

Gear for this race

Chosen for 161 km of trail.

  • Trail Running Shoes 161 km of trail — cushioning that is still there in the last quarter.
  • Race Nutrition Past 161 km the palate quits before the legs do — carry more than one flavour.
  • Hydration Vests Flask capacity for 161 km, without the bounce.
  • Headlamps 161 km almost certainly means running into the night.
  • Accessories Chafe and blisters end more 161 km races than fitness does.

Overview

The Ochil Ultra 100mi is a 161 km trail race held in Sterling, United Kingdom, scheduled for September 25, 2026. Organised by Wee Run Events with an entry fee of £120, the event operates on a scale smaller than 98% of 100mi fields—and bigger than 0% of them—leaving participants to navigate the distance largely in isolation.

With only 1 recorded edition in 2023 that saw a single 1 finisher, runners taking on the route face a uniquely solitary test with none of the on-course pack dynamics found in larger ultras.
