Sri Chinmoy 7 & 13-HR Races : Seattle, WA

The Sri Chinmoy 7 & 13-HR Races are timed loop running events held on a 1.54 mile loop at Magnuson Park in Seattle. The course passes views of Lake Washington and includes some wooded single track. Surfaces include pavement, gravel and chip material. Start and finish are located by the swimming beach, and there is plentiful free parking nearby.

Race services include chip lap counting and a well-stocked aid station. The aid station supplies water, electrolytes, packaged items, potatoes, simple sandwiches, nuts, fruits, vegetables, basic first aid and common caffeinated drinks.

Awards are given to the top two male and female finishers in both Under 60 and 60 and Over categories; medallions and certificates are provided for participants and a post-race boxed vegetarian meal is offered by the lake. A running T-shirt is included in the entry fee; entries received by April 23 are eligible for a race T-shirt.
