Online registration closes the Friday before the race at 11:59 PM PT. Participants 24 years old and under receive a 20% registration discount. The event is cupless: all runners must carry a refillable container. Every finisher receives a piece of handmade finisher swag produced using solar power. Maps and printable course PDFs are provided; distances and elevations are approximate.

Course and logistics

The event uses three loops: a 12K loop, a half-marathon loop, and a 50K loop (the 50K runners complete their loop twice). All distances start and finish at the main Squak Mountain trailhead and begin with a steady, significant climb. The half and 50K courses summit the southeast peak and later the west peak, use parts of the Chybinski Loop, and descend west past the old Bullitt homestead remnants. The trails remain open to other users, including equestrians and hikers.

Aid station mile locations:

  • 12K: 3.4 miles
  • Half: 6.2, 9.7 miles
  • 50K: 6.2, 9.7, 13.0, 19.2, 22.7, 26.0 miles

Parking requires a Washington Discover Pass. Parking at the trailhead is very limited; 50K runners receive priority at the May Valley Loop trailhead. If the lot is full, park on S.E. 135th St. Do not park on May Valley Rd. Visit the organization's website for the most recent information.
