IRONMAN Florida Course Profile

Swim

Ocean swim

8%+ pace penalty. Sighting, breathing rhythm, and bilateral breathing help.

Treat the swim with open-water caution even when the race is known as fast; ocean conditions can change the rhythm quickly.

Bike

Flat / fast bike

Neutral modifier. Steady power, long aero position, watch headwind fatigue.

The planning risk is less climbing and more holding steady effort without getting greedy early.

Run

Flat run

Neutral modifier. Focus on cadence, fueling, and pacing discipline.

A flat marathon rewards patience, fueling, and not turning the final 10K into survival mode.

Wetsuit

This profile uses a wetsuit-friendly planning assumption. WetsuitWetsuitNeoprene suit worn during the swim for buoyancy, insulation, and hydrodynamics. Legal when water temperature is below a race-specific threshold. use can improve buoyancy and reduce swim cost, but the actual effect varies by athlete, fit, water temperature, and race rules.

Official water-temperature readings and race-day rules override any historical assumption.

Tire recommendation

All-purpose slicks

Flat terrain favors aero position and steady watts. Medium-width slicks (25–28 mm) at high pressure offer low rolling resistance with enough cornering grip.

Cutoff pressure

Usually more friendly than hilly full-distance courses, but late wind, heat, and swim conditions can still erase buffer.

Best use

Build a conservative bike cap and protect the run; this course is fast only if the first half of the day stays controlled.
