Halloween Trick or Trot Run 5K/10K/13.1 SAN DIEGO

Halloween Trick or Trot Run 5K/10K/13.1 SAN DIEGO takes place on the streets of San Diego, California, on October 31, 2026, with the half marathon (13.1 miles), the 10K, the 5K and a family one-mile fun run all starting at 7:30 a.m. The annual event welcomes runners of every level and finishers pick up a runner shirt and a finisher medal.

Three timed distances on one morning make this easy to slot into a plan: race the half if it is your goal event, or use the 10K or 5K as a sharpener on the way to something later in the year. Wave sizes are capped, so the first mile does not turn into a shuffle. Complimentary snacks are on hand at the finish, and a virtual option is open to anyone who cannot get to the start line in person.
