Waco swim, official 2026 map needed
Find water rhythm without assuming the old river course
The down-river Brazos flow helps everyone, so settle into your own rhythm rather than racing the field around you.
Seed honestly. Settle into rhythm.

IRONMAN 70.3 Waco.
Race Waco on your terms.
In Waco, a good race begins with knowing which bike route you're actually riding. The roads changed in 2026: the turn moved towards Chilton rather than China Spring. Once that's sorted, your job is simple enough. Ride a number that leaves a half marathon.

Your day in Waco
What could you race?
I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Waco could look like.
The course behind your race
Different roads. Same responsibility.
The 2026 bike takes you through Robinson towards Chilton before returning to the Waco race precinct. That changes the rhythm of the ride and makes old route notes less useful. Keep your effort measured, and don't pretend the missing swim and run details are already settled.
Robinson direction, outbound 2026 bike
Set a sustainable effort as the roads open
Waco moved the bike route south towards Chilton in 2026. Set your sustainable watts for the course you are actually riding rather than an older China Spring map.
Watch the watts, not the speed. Fuel early.
Chilton turnaround, current bike change
Keep your power stable rather than chasing the return speed
Finish your nutrition before T2. Two run loops ahead will expose anything spent chasing the bike's reputation.
Stay aero. Finish planned nutrition.
Waco race precinct, opening run pending
Let your stride recover before deciding pace
Let the first shaded loop through Brazos Park East and Cameron Park feel easy, not fast.
Easy first aid station. Check posture on the rollers.
Indian Spring Park area, run finish pending
Use a late increase only after the route is known
Only progress once the first loop has held together, saving something for the Suspension Bridge finish.
Stay tall. Choose the last move late.
What to check in race week
Before race day, check the swim entry and buoys, then follow the actual Robinson-to-Chilton bike map rather than the older China Spring course. Confirm the current run turns, transition access, road closures and aid around Indian Spring Park.

Prepare for Waco
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: the athlete is prepared to adapt to a genuinely changed bike route while retaining an economical swim and a measured first kilometre of running.
I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Waco.
