Event Overview

The Bristow Loop Race is a timed endurance event held at Elijah Bristow State Park, located approximately 30 minutes east of Eugene, Oregon. Participants compete on a 1.05-mile loop to see how many miles they can complete within a specific time frame. The course is predominantly dirt trail with a small paved section near the timing area. With only 16 feet of elevation gain per lap, the terrain is considered flat.

Race Options

The event offers several timed categories to accommodate different goals:

  • 24-hour run
  • 12-hour Day run
  • 12-hour Night run
  • 6-hour run

The nighttime option is specifically designed for those wishing to practice running in the dark. For the 24-hour category, pacers are permitted to join runners after the first 12 hours of the race.

Support and Facilities

A fully stocked aid station is available every lap, offering water, electrolyte drinks, gels, and various snacks. Runners can also order hot food from a rotating menu, including vegan and vegetarian options. Participants may set up personal support areas in the designated crew space along the course.

On-site camping is available the night before the event for a small fee, with space for tents in the field near the aid station. Facilities include water and restrooms. Due to limited parking, there are strict size restrictions for vehicles; RVs and trailers are not permitted.

Awards

All participants receive a finisher pint glass. Special prizes are awarded to the top three finishers in the men's, women's, and non-binary categories for each race duration. Runners who complete at least 100 miles earn a commemorative buckle. Visit the organization's website for the most recent information.
