Halloween Trick or Trot Run 5K/10K/13.1 2026

The Halloween Trick or Trot Run is a San Francisco running event with 5K, 10K, and half-marathon options, plus a 1-mile Family Fun Run. It is designed for runners seeking a holiday race over a standard road run, with post-run Halloween candy provided. Virtual 5K, 10K, and half-marathon entries are also available for those who prefer to complete the distance independently. Registration is organized into waves, and each wave closes upon reaching capacity, encouraging early sign-ups. Runners may select an Eco-Registration for the 5K, 10K, or half marathon to forgo the race shirt. The availability of short, long, family, virtual, and no-shirt choices offers greater flexibility than a single-distance Halloween fun run.
