The Ascension Seton CapTex Tri presented by Life Time begins with a swim in Lady Bird Lake, with the spectacular backdrop of the downtown Austin skyline.

Bursting out of T1, athletes exit the northeast corner of transition, loop around the parking lot, then climb atop the South 1st Street Bridge. After crossing the bridge, cyclists head north to the Texas Capitol, return through the heart of downtown Austin on Congress Avenue and head west along Cesar Chavez Street and Lady Bird Lake, just past the MoPac Expressway, and back to the 1st Street bridge.

The run course runs across the South 1st Street bridge, loops through Butler Park and the Palmer Events Center before the rousing finish and lively post-race party at in the park with sweeping views of downtown!

Run Course


There are two transition areas, one for rookie and sprint distances and one for olympic distance events. Wristbands have to be worn to enter transition, no exceptions.

Racks will be labeled based on Age Group. Please rack neatly with your items under your bike. 7-8 bikes should fit per rack. Please do not set out anything on Sunday as Sunday is for bike check-in only; everything else will come with you Monday morning.

Once transition closes, you will not be allowed back in. There is overnight security for the entire site.

There will be mechanics in transition for any last minute needs, and they will have bike pumps for airing up your tires.

Only participants are allowed in transition, friends, and family (including children and pets) must wait outside of transition.

Bike Check-in

Pre-Race Bike Check-in is mandatory for all participants.

All bikes must be checked in by 6:30 PM Sunday and your bike must have your bib sticker attached to be dropped off in T1.

There is no bike check in on race morning. 

Bike Check-in will occur on Sunday at the transition area of Auditorium Shores. Bike check-in is at the southwest corner of transition near the finish line. Please refer to the Site and Transition Map for location details.

Your must wear a wrist band and your bike must be numbered before you can check it in, so you will need to attend Packet Pick-up first.

Bikes will not be allowed to be removed from the transition area once inside for any reason unless you are wearing your wristband and have your corresponding bib number.

Please do not use a cover on your bike after racking in transition.

Marking Your Spot

The best way to mark your spot is with a bright colored towel. No balloons are allowed and will be taken down. Do not tape or mark the transition racks.

Race Morning Gear Check-In

You will enter through the “Run Out” gate on the west side of transition to get your gear set up on race morning. The east exit will be closed completely.

Bike Check-Out

Bikes will not be allowed out of Transition until the final cyclist has completed the bike course. It is expected that this will be around 10:45 AM. Participants will be allowed back into transition after they finish, but bikes may not be removed from the racks. Please be courteous to your fellow participants.

Relay Transition Area

A designated relay area will be available near the run out area of the transition. Relay teams will use this area for both transitions. Swimmers will meet their biker in the pen. Biker will run to their designated bike rack, put on the timing chip and exit. Upon return, biker will rack their bike and meet their runner in the relay pen. Runner will exit to complete the race.


Aquabike is a swim- bike event. Aquabike participants start in their designated swim wave. Timing ends for Aquabike participants at the entrance to transition after the bike. From there they can take their time racking their bike and can choose to go through the finish chute to claim their finisher medal or can pick one up at the back of the finish chute.

Aquabike races are usually comprised of athletes who:

  • Are strong swimmers and/or cyclists
  • Enjoy cross-training for other disciplines
  • Do not enjoy or have an affinity for running
  • Have an injury that prevents any running or running long distances
  • Love the multisport lifestyle

All aid stations will be stocked with water and sports drink. There are no aid stations on the bike course. There is an aid station at the swim exit.
