Race Intelligence · Florianopolis, Brazil
An IRONMAN is long enough without racing someone else's schedule. Brazil's 2027 rules include a bike checkpoint at kilometre 130, but the final 2027 layout still needs checking. Respect the clock without letting it force a foolish start.

Your day in Florianópolis
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 Florianópolis could look like.
The course behind your race
There is a 130 km bike checkpoint to respect, but it is no reason to ride the first half as a race against the clock. Check the 2027 transition layout around Jurerê rather than assuming an older arrangement returns.
Jurerê swim area, final beach pending
Calm water can make this a quick swim. Settle into a controlled rhythm and let the conditions do the work rather than adding unnecessary effort.
Settle by 400 m. Hold a controlled, repeatable effort.
Florianópolis bike, opening kilometres
The flat countryside course offers speed, but wind is what makes this race difficult to pace. Set a power number that accounts for wind, not the flat road alone.
Cap power on any exposed stretch. Fuel early while conditions allow it.
Full-distance bike, middle stage
Whichever direction the wind is working against you on this loop, hold your power number rather than chasing a speed target the wind won't allow.
Ride the wind on power, not speed. Stay on the fuelling schedule.
Bike course, towards the 130 km checkpoint
The second loop repeats the same flat, wind-exposed terrain. Ride to the same power ceiling regardless of which way the wind has shifted.
Compare effort to loop one. Finish planned nutrition before T2.
Florianópolis marathon, first kilometres
Passing Avenida dos Buzios, where local TriClubs set up their own support tents, is one of the day's loudest moments. Let the first loop feel deliberately easy despite the crowd.
Shorten stride out of T2. Hold opening pace regardless of the noise.
Marathon middle section
Passing the same crowd-lined stretch a second time gives a clear read on how loop one's pace is actually holding, especially if the wind has picked up.
Compare loop two to loop one. Keep fuelling on schedule.
Florianópolis marathon, last 12 km
This is where a bike ridden honestly against the wind, or not, starts to show up in the legs. Manage the effort you actually have.
Reassess goal pace honestly. Keep taking aid on schedule.
Full-distance finish approach
The final loop finishes among Florianopolis's warmest crowd support. If the bike respected the wind and the first three loops were paced evenly, this is where it pays off.
Decide the finish honestly. Save something for the final loop's crowd.
Before racing, check the 2027 swim entry, transitions, full bike and marathon turns and the 130 km cycling checkpoint against your rolling-start schedule. Don't rely on old bag procedures or transition maps. Work out the time margin, then let your pacing plan govern the ride.

Prepare for Florianópolis
A finish range gives you something to work towards. The preparation is specific to this race: the bike pacing and nutrition plan includes the intermediate checkpoint without encouraging a panicked start, and the marathon opens at a genuinely sustainable effort.
