Sunrise Marathon 5K/10K/13.1 SAN DIEGO

Sunrise Marathon 5K/10K/13.1 SAN DIEGO takes place in San Diego, California, on December 12, 2026, with the half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run all starting at 7:30 a.m. on a scenic course timed for sunrise. Optional timing is available, and athletes get a performance race shirt, a finisher medal and a digital training pack.

Treated as the close of a fall block, this is a satisfying place to spend whatever fitness you have built since September. The half is long enough to be a genuine test of that work and short enough to recover from before the new year, which makes it a sensible bridge into a spring marathon build. Runners who lost weeks to injury or travel will get more from the 10K, and the one-mile keeps younger family members in the day.
