Sri Chinmoy Self-Transcendence 7 and 13 Hour Races
The event offers timed loop running in two time-limited formats: a seven hour race and a thirteen hour race. Both races take place on a scenic 1.54-mile loop in Magnuson Park, Seattle, featuring mixed surfaces (pavement, gravel and chip), some hills and wooded single track that provide occasional traillike sections and views of Lake Washington. The start and finish are located by the swimming beach, with free parking nearby.
Lap counting is handled with chip timing. A well stocked aid station provides water, electrolytes, packaged food, potatoes, simple sandwiches, nuts, fruits and vegetables, and caffeinated drinks; participants are encouraged to bring a personal bottle to reduce cup waste. All participants receive medallions and certificates; awards are given to top finishers in the event age categories of under 60 and 60 and over. A running t-shirt is included with entry and registering by April 23, 2026 guarantees a shirt. A boxed vegetarian post race meal is provided by the lake and outdoor showering and swimming facilities are available after the race.
The event is sanctioned by USA Track and Field and is organized by the Sri Chinmoy Marathon Team. Entry is limited to 65 solo participants for 2026. Proceeds support the Sri Chinmoy Oneness Home Peace Run. Races are open to runners 18 and older. Visit the organization's website for the most recent information.
