Survival of the Fittest 18K
Test your grit on Squamish’s most thrilling singletrack adventure
Overview
Survival of the Fittest is where Squamish’s rugged beauty and trail running spirit collide. Starting from the scenic Capilano University campus, runners are launched straight into a wild mix of flowing singletrack, challenging climbs, and exhilarating descents, all surrounded by sweeping views of the Tantalus Range.
Both distances feature legendary local trails with names that inspire and intimidate—Legacy, Megacy, Somewhere Over There, and Hoods in the Woods—before testing your resolve on two iconic bridge crossings over Darwin’s and Carpenter’s Son. This is a race that brings community, challenge, and pure trail running joy together in one unforgettable day.
The 18 KM is fast and fiery, drawing some of the strongest local talent every year, while the 35 KM is a season starter for runners chasing big summer goals. And don’t miss the Kids Race, a lively, non-competitive event that celebrates the next generation of trail lovers.

About Coast Mountain Trail Series
Coast Mountain Trail Running (CMTR) produces some of British Columbia’s most beloved and challenging trail races. Founded by Gary Robbins and Geoff Langford, CMTR blends rugged coastal terrain with top-tier race organization, fostering a deeply loyal community of trail runners across all ability levels. Their events range from winter snowshoe and multisport races to legendary ultras like the Squamish 50 and Diez Vista 50K.
Each race reflects CMTR’s commitment to sustainability, inclusivity, and community stewardship. They operate as a carbon-neutral company (aiming to go carbon-negative), donate $5–$10 per race entry to local search and rescue and trail organizations, and plant one tree per runner through an Indigenous-led reforestation partnership. To date, they’ve donated over $465,000 and planted more than 16,000 trees.
From technical alpine climbs to beginner-friendly non-technical trail half marathons, CMTR’s event calendar offers something for everyone. With an energetic volunteer crew, thoughtfully marked courses, and a commitment to local impact, these races are more than just events, they’re celebrations of community and the wild beauty of BC’s backcountry.
