What Makes It Great

A punishing 79km loop starting and finishing in downtown Squamish, the 50 Mile runs nearly entirely on technical singletrack and packs over 3,500m of climbing and descent through the Sea to Sky network above Howe Sound. The infamous Galactic Scheisse climb rises 750m over 4km to ~1,000m elevation, and the back half of the course is significantly harder than the front. Earns ITRA 3 performance points and hosted the 2023 Canadian Mountain & Trail Running Championships and 2024 Canadian Trail Running Championship.

Galactic Scheisse summit
A sustained 750m+ climb to ~1,000m with panoramic views of Howe Sound and the Tantalus Range glaciers
Canadian Championship venue

Crew Access Points

Pacer Rules

No Pacers Allowed

Crew Rules

  • Crew access is permitted at AS2 (Alice Lake, km 19.8), AS5 (Capilano University, km 51.8), and AS7 (Far Side, km 68.9). All three are Park-and-Walk locations — plan for a ~5 minute walk from nearest parking to the aid station.
  • Crew access is strictly forbidden at AS3 (Corners), AS4 (Fred), and AS6 (Garibaldi Road). Any vehicle seen attempting to access these areas will result in the runner's immediate disqualification.
  • Runners may only be crewed within 30 metres of an aid station. Being crewed further away risks disqualification.
Weather

August in Squamish is warm and generally dry, with valley temperatures ranging 20–28°C (68–82°F) on race day. The 50M starts before sunrise at 5:30am in cool darkness (10–15°C at the gun). The course climbs to ~1,000m on Galactic Scheisse where temperatures are noticeably cooler. Wildfire smoke is an annual risk in the Sea to Sky region — the race has a wildfire smoke policy. Afternoon thunderstorms are possible on exposed ridgelines. August is statistically one of the driest months in Squamish.

Gear Rules

No trekking poles

Required Gear

  • Headlamp (minimum 100 lumens) (Mandatory at the start line for all runners. Any runner departing AS7 (Far Side) after 6:00pm must carry it to the finish — runners without a headlamp will be pulled from the course. At AS2 (Alice Lake), runners may carry it, pass to crew, or drop in SQ50-labelled transport buckets for transport to AS7.)
