IRONMAN 70.3 Texas 2027
A protected bayou swim off Moody Gardens, a flat out-and-back along the Galveston seawall, and a three-lap run finishing at the Aquarium Pyramid.
33 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.

Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“Completely flat and completely exposed, which means the wind is not a footnote here, it is the course. Practise holding an aero position into a headwind, because there is nowhere on this island to hide from one.”
The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, only a live tracker that runs on race day, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
Protected salt water in Offats Bayou, starting from the white sand of Moody Gardens' Palm Beach and finishing beside the Colonel paddlewheel boat. Averages 72°F. The official page does not state a lap count.
One flat out and back along the Gulf coast: out of Moody Gardens onto the Seawall, south to the end of Galveston Island, over San Luis Pass onto the mainland through undeveloped coastline, then back. No shelter anywhere on it, so the wind decides the split.
Three flat laps through Moody Gardens, along Offats Bayou and Palm Beach, finishing by the blue Aquarium Pyramid with the crowd stacked around it.
Not yet confirmed for this edition: swim lap count, bike elevation gain, transition locations, cut-off times, water temperature history. We publish these only once they are on the official course page, so check there before you pace off anything here.
