Faster than most Texas sprint triathlons

Compares the fastest quarter of each field, so walkers and first-timers do not skew it. It reflects the course and the field together: a flat course, cool weather, or a competitive crowd all make times faster.

The 23rd Annual Oilman Texas Triathlon is southeast Texas' favorite locally-produced Half Iron Distance Triathlon. New last year was the Sprint distance triathlon, offering more options to more athletes.
Saturday, the Sprint distance will include a 500 meter swim, 11 mile bike and a 5k run through the Margaritaville neighborhoods and golf course. We also will have a 5K and Kids Du. Athletes will enjoy a taste of the Sunday course, with a mix of roads and golf cart paths, with the same transition and finish line celebration. Including of course, a mechanical bull!
Come for the race, stay for the weekend! Be sure not to miss our "5 O'Clock Somewhere" Fun Tri, the most amazing triathlon-themed pool party ever.
