GALVESTON – The IRONMAN 70.3 Texas Triathlon returns to Galveston this Sunday, bringing thousands of athletes and expected traffic delays across parts of the island.
According to event organizers, more than 2,000 athletes from around the world will compete in the race on March 29. The triathlon includes a 1.2-mile swim, a 56-mile bike ride and a 13.1-mile run.
The event begins at 6:45 a.m. and is expected to continue into the early afternoon.
