All courses start and finish adjacent to the South (main) parking lot off Novelty Hill Road. All have low to moderate climb and mostly relatively wide, smooth trails, with few steep parts.
The 5-mile course is a figure-8, with runners leaving the start and returning to the finish via the same trail.
The 10-mile course is two times around the 5-mile course.
The Marathon course is four identical laps, which generally follow the 5-mile course route but have two added out-and-back sections. Marathon runners will pass by the aid station at the start/finish three times, and there will be an additional aid station 3.54 miles into the 6.55-mile Marathon course loop, for a total of seven well-spaced aid stations for Marathon runners.
For a more detailed route description, including the location of aid stations, visit the Redmond Watershed Preserve trail run at Northwest Trail Runs.
Northwest Trail Runs provides courses that are clearly marked and precisely measured, we record a finish time for all finishers, and we post results to the website after the event. Longer courses will have aid stations, and there will be refreshments at the finish.
