About the Event

The Lemurian Ascent Trail Run returns to Mount Shasta in California on June 27th, offering runners a unique mountain challenge that combines sustained climbing with exhilarating descents through the Mt. Shasta Ski Park. This event is deeply rooted in the community and draws participants from far and wide who are eager to tackle its challenging terrain.
Set against the backdrop of Mount Shasta's forested slopes, the Lemurian Ascent Trail Run unfolds amidst a tapestry of vibrant greenery and towering pines. The race day atmosphere at Mt. Shasta Ski Park is one of relaxed camaraderie, with scenic chairlift rides, yard games, food stalls, and an open bar inviting runners to linger long after crossing the finish line. This event not only celebrates athletic achievement but also fosters a sense of community among trail enthusiasts.
The Lemurian Ascent Trail Run has been held annually since its inception as part of the Mt. Shasta Ski Park's summer festivities, with each year seeing an increase in both participation and enthusiasm. The race supports local charities that focus on environmental conservation and community health initiatives, making it a meaningful endeavor for athletes looking to give back while pushing their limits. Over 200 runners are expected this June, drawn by the allure of scenic vistas and challenging ascents.
The Lemurian Ascent Trail Run features three distinct courses catering to various skill levels: the Long Course at approximately 15 miles with over 3,500 feet of elevation gain; a Shorter Option spanning roughly 4.5 miles; and an intermediate route covering about 7 miles. Each course incorporates a mix of ski trails, service roads, and singletrack paths within Mt. Shasta Ski Park.
The long course is meticulously designed to showcase the vertical profile of the ski area by having runners climb to the top of each chairlift before descending back towards the base. Key features include significant ascents followed by wide-open mountain views and lengthy descents that connect lift-served areas across the park. The shorter options maintain the spirit of the event with their own unique challenges, offering a more approachable yet still demanding experience.
Race day conditions are expected to be cool but sunny, typical for early June in Mount Shasta. Temperatures will hover around freezing point during the morning hours before gradually warming up as the sun climbs higher into the sky. The trail surface is firm and slightly soft underfoot, requiring runners to consider appropriate footwear that can handle both dry and potentially damp terrain conditions.
