Holiday Half Marathon, 10K (6.65 miles), 5K, Fun Run (0.88 miles)

Holiday Half Marathon, 10K (6.65 miles), 5K, Fun Run (0.88 miles) is held in Goleta, California, on December 12, 2026. The half marathon (13.1 miles) starts at 8 a.m., the Grinch 10K, measured here at 6.65 miles, at 8:30, the 5K at 9 and the 0.88-mile fun run at 9:45.

The staggered starts are the useful detail: nearly two hours separate the first gun from the last, so one runner can race the half while the rest of the family turns up later for the shorter events. For the 13.1, ten to twelve weeks with a weekly long run around 10 miles is the standard preparation, and a couple of runs at goal pace will tell you what to expect. The 10K, slightly over the usual distance at 6.65 miles, is a solid hard effort for anyone not ready to go long, and the fun run gives young children something they can finish.
