Ascension Seton Supertri Austin 2027
A Memorial Day Monday triathlon in Austin: swim Lady Bird Lake, ride through the city past the Texas Capitol, run through Butler Park and finish at Auditorium Shores. SuperSprint, Sprint and Olympic distances.
34 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? Olympic distance 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.
Build my complete road.
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.
“All three distances start on race-morning Monday, with the Olympic first at 7:00 AM, so rehearse an early start: breakfast timing, transition set-up and a warm-up that works before a first swim wave. The organiser notes that several waves have already sold out.”
