Harbor Half Marathon

Harbor Half Marathon takes place in Corpus Christi, Texas, on October 31, 2026, along the coast. Four road options are available: a 5K, a 10K, an individual half marathon (13.1 miles) and a half marathon run as a relay.

The route follows the waterfront and passes through downtown Corpus Christi, with views over the water for much of the way and the sea breeze that comes with the Texas coast. That wind is worth respecting in your pacing, since running the exposed sections a few seconds per mile slower is usually faster overall. The relay is a sensible entry point if 13.1 miles on your own still feels out of reach, and the shorter distances suit anyone building fitness toward it.
