Gear for this race

Chosen for 100 km of trail.

  • Trail Running Shoes 100 km of trail — cushioning that is still there in the last quarter.
  • Race Nutrition Past 100 km the palate quits before the legs do — carry more than one flavour.
  • Hydration Vests Flask capacity for 100 km, without the bounce.
  • Headlamps 100 km almost certainly means running into the night.
  • Accessories Chafe and blisters end more 100 km races than fitness does.
