Hardrock 100

Written by Catriona Adams. Published 8 September 2026

Averaging over 11,000ft of elevation through Colorado's San Juan Range, Hardrock is entered by weighted lottery alone — and just applying requires a qualifying 100-mile mountain ultra in the previous two years. 102.5 miles, 33,000ft of climb, 48-hour limit.

Key points

  • 102.5 miles through Colorado's San Juan Range, 33,000ft of climb, averaging over 11,000ft elevation — the course crosses above 12,000ft thirteen times.
  • Entry is by weighted lottery only: 146 places, selected each December, and a qualifying 100-mile-plus mountain ultra completed in the previous two years is required just to apply.
  • Devised over the winter of 1991-92 by Colorado ultrarunner Gordon Hardman with John Cappis, Charlie Thorn, Dale Garland and Rick Trujillo, tracing the route on USGS survey maps before the first race that summer.
  • The course alternates direction — clockwise one year, counterclockwise the next — so records are tracked separately for each direction. No finish line: runners "kiss the Hardrock", a ram's-head image painted on a block of mining debris.

The course alternates direction — clockwise one year, counterclockwise the next — which is why records are tracked separately for each direction rather than as a single overall time.

48 hours, though the average finish takes around 41 hours 10 minutes.

No — Hardrock alternates direction (clockwise and counterclockwise) between years, which is why current records are recorded separately for each direction.

Colorado ultrarunner Gordon Hardman first proposed it in 1991; John Cappis, Charlie Thorn, Dale Garland and Rick Trujillo joined to develop the route over that winter, plotting it on USGS survey maps before the first race in summer 1992.

Yes, by design — its lottery pool is far smaller (146 places) and every applicant already needs a qualifying 100-mile mountain finish, unlike Leadville's open entry or Western States' broader qualifying-race list.
