Spooky Dam 5k, 10k, 15k, Half Marathon 2026

Spooky Dam is a Halloween-season running series at Hansen Dam in Los Angeles, offering 5k, 10k, 15k, and half marathon distances. Races begin in the morning and are organized by A Better World Running. Costumes are encouraged, making it a more casual and playful event than a standard road race. The start and finish are located on the path opposite Hansen Dam Skate Park, with free parking available in a nearby lot. The course is an open out-and-back route where runners share the path with pedestrians, other runners, and cyclists. It's straightforward to navigate, featuring a single small hill around 0.6 miles from the start. An aid station on each loop provides water, Gatorade, and Gu gels. The 5k completes one loop, the 10k two, the 15k three, and the half marathon consists of three 4.36-mile loops. Participants receive custom medals, goodie bags, complimentary photos and videos, snacks, and results posted online within 12 to 24 hours.
