Kendall Mountain Run

Kendall Mountain Run is an annual trail running event in Silverton, Colorado, featuring mountain routes that start in downtown Silverton and climb on jeep roads toward the summit of Kendall Mountain. The course rises from about 9,318 feet to roughly 13,066 feet and includes a final 300-foot scramble to the summit on the 12 mile course. The 12 mile route continues over the backside and rejoins the original line at the Notch; in some conditions runners are turned at the Notch instead of summiting.

Distances:

  • 12 Mile
  • 11K (about 6.8 miles)

The 12 mile course lists about 3,960 feet of elevation gain; the 11K lists about 1,616 feet of gain and a turnaround at Deer Park. Aid stations are located at Deer Park and at the Notch; there is no aid station at the summit on the 12 mile. The event is cupless: participants must carry their own container for refills at aid stations. Drop bags are managed at the start/finish area and some aid stations accept drop bags for the 11K.

The race traces roots to a 1908 wager and has been held annually since 1978. Race services include chip timing, finish photos, well stocked aid stations, finisher awards, age group awards, and a Mountain Duo Challenge for participants who enter both weekend races. Crew access is limited to start and finish areas and pacers are not allowed. Visit the organization's website for the most recent information.
