Why this race

  • Iconic 100-mile ultra running since 1983, featured in 'Born to Run'
  • High-altitude Rocky Mountain course with a strong identity of its own outside UTMB
  • Life Time flagship event, followed worldwide

If you like Western States 100 or Hardrock 100, you'll like this one.

Pack this

  • Waterproof shell jacket plus warm layer, gloves and beanie for night
  • Headlamp with spare batteries and a backup handheld light
  • Hydration vest with two 500ml soft flasks + electrolyte tabs
  • Gels/chews for roughly 250-300 kcal per hour plus real-food options
  • Labeled drop bags with dry socks, spare shoes and anti-chafe balm

What you should know

  • The course sits at 2,800-3,800m; arrive early to acclimatize and watch for altitude sickness symptoms.
  • Hope Pass (~3,840m) is crossed twice; expect steep climbs, rocky descents and fast-changing weather.
  • Afternoon thunderstorms are common in August; get off exposed ridges quickly if lightning approaches.
  • Strict aid-station cutoffs apply over a 30-hour limit; check the official cutoff times before race day.
  • Nights in Leadville can drop near freezing even when days are mild, so plan layers for the night stretch.
