THE ENDLESS RUN

The Endless Run is a point-to-point trail race that follows the Grand Ridge Trail from Duthie Hill Park to Central Park in Issaquah. The course runs for just over 7 miles and climbs nearly 1,000 feet, moving through forested singletrack with a mix of flowy sections, punchy climbs, and fast descents. The route finishes with a rolling descent into Central Park and a final uphill sprint to the finish line.

The event is held to mark the longest day of the year and features evening light conditions along the ridge. There are no aid stations on course; participants are expected to be self supported. Refreshments are provided at the finish line. Gear transportation to the finish is available for those who need their belongings moved from the start area.

Entry details include a flat adult fee of $40 with no added fees and free entry for children under 17. Competition categories are U19, 20-29, 30-39, 40-49, 50-59, and 60+. The fastest male and fastest female overall each receive $50, and the top three finishers in each category receive awards. Recommended parking is offered on nearby church grounds because the Duthie Hill Park lot closes at dusk. Visit the organization's website for the most recent information.
