Oilman Texas Triathlon

Oilman Texas Triathlon takes place in Montgomery, Texas, on November 14–15, 2026, at the Margaritaville Lake Resort on Lake Conroe. Saturday, November 14, brings the Sprint Triathlon (500-meter swim, 11-mile bike, 5K run) and the Island Time 5K (3.1 miles), both starting at 7:00 a.m. Sunday, November 15, is the main event: the half-distance triathlon (1.2-mile swim, 56-mile bike, 13.1-mile run) and an Aquabike, also at 7:00 a.m.

The half-distance swim is in the lake, the bike heads out through Montgomery County, and the run circles the resort; the sprint keeps the same swim-bike-run structure on a shorter course through the Margaritaville neighborhoods. Fields are capped, so entries are limited. For runners, the Island Time 5K is a standalone option or a way to join a friend's race weekend, and the sprint is an approachable first triathlon. The half distance calls for a 16- to 20-week build across all three sports, with a long ride and long run each week and brick sessions to practice running off the bike.
