About the race

Spring Awakening Backyard Ultra is a backyard-format running event on Vashon Island using a 4.167 mile island-center forest loop. Participants must complete each loop within one hour and be back in the start corral to begin the next loop; failure to return to the corral on time results in elimination. A new lap begins every hour for up to 24 hours.

Individual options:

  • 6-hour option: 25 miles (6 yards)
  • 12-hour option: 50 miles (12 yards)
  • 24-hour option: 100 miles (24 yards)

Teams may enter as relays with up to eight members; team members may structure exchanges as they choose so long as someone from the team completes each yard. Runners may have a personal area with tents and chairs near the start/finish; power outlets are not available. Crews are allowed, but no pacers or non-competitors may be on course. Artificial aids, including trekking poles, are not permitted.

The start/finish area, aid station, portajohns, and team tent space are located in the field behind O-Space (18870 103rd Ave SW). A fully stocked aid station at the start/finish will offer water, electrolyte powders, sodas, sweets, salty snacks, fruit, basic medical supplies (no NSAIDs), and cooked meals during the event. Registered entries receive event items such as a T-shirt, custom bib, food access for runners and crew, a commemorative koozie, sticker and magnet, and 24 hour emergency support. Individual 24-hour finishers receive a custom prize. Visit the organization's website for the most recent information.
