Oilman Texas Triathlon
About this race
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.
