Shedhorn Skimo 2025

The Shedhorn Ski Mountaineering Race returns to Big Sky March 8th! In this world-class endurance race, you'll work against gravity and come away knowing you completed the toughest skimo race course in the country. Taking you up long climbs and down big mountain descents like the Big Couloir, this race is not for the lighthearted. This race has two distances, and a kids race.
 
Pronghorn: (7+ miles, and 4,500 ft of vert) Climbing to the top of Lone Peak, descending the Big Couloir, and then up and over the Headwaters Ridge, this shortened version of the Shedhorn is still a test of mountaineering feats:
2 alpine climbs with exposure over cliffs and avalanche paths
Max elevation of 11,166 feet above sea level
50°+ boot packs
2 alpine ski descents on 45°+ terrain
 
Shedhorn: (16+ miles and 8,000 ft of vert) Summiting Lone Peak twice and descending the classic Big Couloir, this route's ups and downs are sure to test even the most advanced athletes. This is a technical ski mountaineering race and is designed to test multiple skill sets:
4 alpine climbs with exposure over cliffs and avalanche paths
Max elevation of 11,166 feet above sea level
50°+ boot packs
4 alpine ski descents on 45°+ terrain
 
Shedling (kids): (3 miles and 720 feet of vert) Kids get to join in on the (type two) fun! The Shedling is for junior mountaineers aged 14 & under, traveling up a skin track, transitioning to bootpack, and returning to the base area.
