Course identity

Hardrock 100 starts and finishes in Silverton, Colorado, on a high-altitude mountain loop whose direction alternates each year. This page pins the 2026-hardrock-official-course version using the organiser's public material from Hardrock Hundred Endurance Run.

Hardrock’s altitude, long exposure and alternating direction mean a single track cannot replace reading the course. The official GPX is one version entry; entry rules, altitude preparation and equipment requirements need separate attention.

Verified facts

• Start and finish are both in Silverton; the route is a high-altitude loop.
• The official distance is 101.8 miles with 33,441 ft of climb.
• Direction alternates each year; confirm the current direction before using a GPX and never mix clockwise and counter-clockwise tracks.
• Distance basis: Official 101.8 miles (about 163.8 km).
• Elevation basis: Official 33,441 ft climb (about 10,193 m)
• The map anchor is a RunMap editorial overview location, not an official start, finish or course coordinate.

What this page does not provide

The organiser provides an official GPX download; this page links to it but does not bundle or redistribute it. It does not treat a third-party track, illustration or elevation sketch as official geometry; race-day routes can also change because of construction, weather or safety arrangements.

How to use this page

Treat it as a pinned-version entry, not a navigation tool. Confirm the year, category and direction, then check the organiser's technical material for that edition. Use the pace calculator for arithmetic and read the marathon distance for training context. Ultra and trail races also require separate checks of mandatory kit, aid spacing, weather windows and escape options.
