Summits Trail Runs at Granby Ranch Resort

Summits Trail Runs take place at Granby Ranch Resort in Granby, Colorado. The event offers multiple trail distances that run on single-track trails through forests, aspen groves, alpine meadows, and mountain terrain. Courses present varying elevation gains and include sections with rugged alpine features and sweeping mountain vistas.

One event, the Elevation Challenge, scores competitors by total elevation climbed rather than by mileage. Only complete loops count toward a participant's mileage. Each loop is 1.92 miles long and includes 832 feet of elevation gain and 832 feet of elevation loss for 1,664 feet of elevation change per loop.

Registration fees for the listed events appear in the event details and vary by distance. The event description notes an emphasis on respect for the natural setting and a community atmosphere among participants.

Distances offered include:

  • 6.1 miles (6-Mile trail)
  • 13.9 miles (Half Marathon)
  • 27.8 miles (Marathon)
  • 33.9 miles (55k)
  • Loop format with 1.92-mile laps for the Elevation Challenge

The races are held at Granby Ranch Resort and route specifics reflect mountain trail conditions and elevation changes. Visit the organization's website for the most recent information.
