Barrier Island Ultra

Barrier Island Ultra is a coastal running event in Port Aransas, Texas, on Mustang Island by the Gulf of Mexico. It offers six distances: 5K, 10K, half-marathon, marathon, 50K, and 50 miles. Runners race on a sand course, choosing hard-packed sand near the water or softer sand near the road, with waves and wind as a backdrop.

The atmosphere blends beach vacation vibes with competitive spirit, finishing on the beach and socializing at The Beach Lodge. The race is cupless, with refill stations and well‑stocked aid along an out-and-back course, and it’s part of the Texas Trail Running Eco Series Eco Challenge.
