2026 Let Your Imagination Run 5k/1k
Let Your Imagination Run is a community running event held on August 30, 2026 in Golden Gate Park, San Francisco, CA. The event includes a children’s 1k and an all-ages 5k, both of which start and finish at the Pioneer Log Cabin Picnic Area. The organizer is the nonprofit For A Good Koss. Proceeds support the organization’s music scholarships and community education events.
The event is presented as the fourth edition of Let Your Imagination Run and is described as a way to celebrate the life of Sarah Koss on the tenth anniversary of her passing. The schedule includes bib pick up before the races, the children’s 1k followed by the all-ages 5k, and a post-race celebration with refreshments, prizes, and a raffle at the Pioneer Log Cabin Picnic Area.
Fees vary by registration date. Early fees and later fees are listed for each distance, and a 15 percent discount is available for teams of four or more. All participants are entered into a raffle and prizes are awarded to the fastest finishers in the all-ages 5k. Road closures affect vehicle access near the start and finish; the closest vehicle access is at the Blue Heron Lake Boathouse, a short walk from the Pioneer Log Cabin Picnic Area.
