IRONMAN 70.3 São Paulo.
Your best day in São Paulo.

São Paulo can feel like a race against the city itself. In the 2026 edition, athletes left the USP rowing lane for major roads and came back to run on campus. None of that is a licence to hurry the first part of a 2027 race.

São Paulo, the cityscape.

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 São Paulo could look like.

Let’s build your race

Your age and race category help me estimate where that performance could place you. They don’t determine how fast I think you can race.

Change units

Leave enough for the campus when you leave the highway.

In 2026, the USP rowing lane gave São Paulo an unusually contained swim before the bike moved onto Marginal Pinheiros and the city's bigger roads. Three campus run laps brought the noise and pace back into the university. It is a vivid race to prepare for, but the 2027 venue may not bring back every one of those roads or laps.

USP rowing lane, prior swim route

Settle into the water rather than fight for early metres

The prior USP rowing-lane swim offered a contained start. Use it to find clean strokes rather than attacking the water because the course looks straightforward.

Start the swim calmly. Build stroke rhythm.

São Paulo city bike roads, early stage

Keep the first acceleration out of your race

The 2026 course moved from USP onto São Paulo's major roads. Let those open kilometres come at your planned effort, not at the speed of the riders around you.

Cap the city-road surge. Hold planned watts.

São Paulo city bike roads, later stage

Fuel for the run instead of a quick road split

On the return towards the university in the previous edition, keep taking fuel. The campus run's repeated laps will expose the cost of skipping that routine.

Drink well before T2. Save strength for the run.

USP campus run, earlier stage

Find a pace you can sustain through the crowds

Coming into the first USP run lap, let your legs change gear without chasing people straight out of transition. Find the pace you can bring back around campus.

Run the opening kilometres quietly. Find your cadence.

USP campus run, closing stage

Let the last campus kilometres be the fastest you deserve

Treat the final campus lap as a decision earned on the earlier ones. If effort and nutrition stayed composed, start racing; otherwise hold a sustainable rhythm.

Judge your remaining effort. Race only if ready.

What to check in race week

Confirm 2027 swim venue and rowing-lane access, the bike closure plan and whether the Marginal Pinheiros corridor is retained. Check the new USP run-lap count and the aid stations on the final course map. The three-lap campus run was the 2026 arrangement; do not use it as a 2027 split marker until the new route is final.

Make your finish prediction and I can send this plan to you in race week.

Build the legs.
Practise the decisions.

A finish range gives you something to work towards. The preparation is specific to this race: race-day urban logistics, a sustained road effort and calm campus running can be executed without using the previous year's course as an unchecked script.

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 São Paulo.
