Seattle, United States • 23 May 2026
Sri Chinmoy 7 & 13 HR Races
This event offers timed loop running races with solo options for seven hour and thirteen hour efforts. The format uses a 1.54 mile loop that keeps runners close to their gear and aid, which simplifies pacing and logistics. Chip lap counting is provided.
The course runs in Magnuson Park and includes views of Lake Washington and sections of wooded single track. Surfaces include pavement, gravel and chip. The start and finish are located by the swimming beach and there is plentiful free parking. Onsite facilities include washrooms, a solar heated outdoor shower and a post race swimming beach.
A staffed aid station supplies water, electrolytes, packaged snacks, potatoes, simple sandwiches, nuts, fruits, vegetables, caffeine drinks and basic first aid. Participants are encouraged to bring their own fluid bottle to help reduce cup waste.
Awards are given to the top two male and female finishers in the Under 60 and 60 and Over categories. All participants receive medallions and certificates and there is a surprise drawing. A race T shirt is included in the entry fee; register by April 23 for a race T shirt. A boxed vegetarian meal is provided after the race.
The Sri Chinmoy Marathon Team sponsors the event and has organized running and multi sport events for decades. Proceeds support the biennial Sri Chinmoy Oneness Home Peace Run. Visit the organization's website for the most recent information.
