From the Organizer
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 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.
Come for the race, stay for the weekend! Resort guests and Day Pass holders will be able to join in our brand new "5 O'Clock Somewhere" Fun Tri, the most amazing triathlon-themed pool party ever.
On Sunday, Half distance athletes will enjoy a 1.2 mile swim in Lake Conroe, 56 mile bike in scenic Montgomery County, and a 13.1 mile run all starting and ending at the beautiful Margaritaville Lake Resort Lake Conroe! The Sprint distance will include a 500 meter swim, 11 mile bike and a 5k run through the Margaritaville neighborhoods and golf course.

About This Sport
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
Three sports, one race — swim, bike, run in sequence, with transitions that are a discipline of their own.
Open water, open roads, and competition with yourself. Cross the finish line knowing what it took to get there.
Swim, bike, run — back to back. The sprint distance makes it far more accessible than most people think.
