Add only the evidence you have. Every control changes a discipline range, its uncertainty, or an execution-risk explanation.

Swim evidence

Replaces the broad pool-to-open-water assumption.

Bike and equipment

These replace broad mass, aerodynamics, tyre, and power-to-speed assumptions.

Run evidence

A recent effort and honest durability/acclimation answers refine the post-bike run.

Race execution

Transition proficiency changes the T1/T2 range and how wet conditions are treated.

02 The course

What Philippines Davao City actually gives you

You swim two laps of Davao City's bay at Bago Esplanade, ride three mostly flat counter-clockwise loops along the coast and MacArthur Highway, past the Tulip Roundabout and across the Sta. Ana Bridge, then run four mostly flat loops out to the Tulip Rotonda and back to finish at Bago Aplaya Esplanade. IRONMAN markets this course directly around its difficulty, urging athletes to 'earn' their finish here, and the reason is conditions rather than terrain: extreme tropical heat and humidity, with air near 31C and water near 28C, is what actually decides the day.

Swim

3.8 km

Ocean Bay, Two Laps

Layout
2 laps of 1.9 km
Setting
Davao City Coastal Road (Bago Esplanade)

A two-lap bay swim at Bago Esplanade, warm at around 28C, gives a straightforward opening before extreme tropical heat becomes the day's real subject.

Bike

180 km

Mostly Flat, Three Counter-clockwise Loops

Layout
3 loops
Setting
Davao City Coastal Road, MacArthur Highway, Tulip Roundabout and Sta. Ana Bridge

Three mostly flat counter-clockwise loops along the coast and MacArthur Highway remove terrain as an excuse, so heat management carries the whole leg.

Run

42.2 km

Mostly Flat, Four Loops

Layout
4 loops
Setting
Davao City Coastal Road, out to Tulip Rotonda and Bago Aplaya Esplanade

A mostly flat four-loop run offers nowhere to hide from the heat that has already built through the swim and bike.

Where these course facts come from

These facts come from the organiser’s latest published material: swim, 2027 current route; bike, 2027 current route; run, 2027 current route. They describe the character of the course. They do not confirm the final 2027 route.

03 Race plan

How I’d want you to race it

One job for each part of this course. The distance markers tell you when the job changes. The course tells you why.

Swim

A warm, straightforward bay swim

  1. 0–3800 m

    Two laps at Bago Esplanade

    Settle into already-warm water

    A two-lap bay swim is straightforward to navigate. At around 28C, the water is already warm enough to be part of the day's heat load, so settle rather than race the first lap.

    • Settle by 400 m
    • Pace by effort, not by the calm bay conditions

Bike

Flat terrain, real heat

  1. 0 km–60 km

    First loop along the coast

    Set a heat-aware ceiling on flat roads

    Along Davao City Coastal Road and MacArthur Highway, the mostly flat terrain invites a power number the tropical heat won't let you hold. Set the ceiling now, before it builds further.

    • Cap power before the heat peaks
    • Start fluid and electrolyte intake early

  2. 60 km–120 km

    Second loop past Tulip Roundabout

    Hold the ceiling as the heat builds

    Repeating the loop past the Tulip Roundabout and across the Sta. Ana Bridge, the flat terrain still offers no natural check on effort. Heat is the real variable now, not the road.

    • Recheck power against the heat, not the terrain
    • Stay on the fuelling schedule

  3. 120 km–180 km

    Third loop, closing the bike

    Finish the flat bike still owing the run nothing

    The final loop is where an honestly-paced ride pays off on the run to come. Protect that by holding your number rather than chasing time back.

    • Finish nutrition before T2
    • Prioritise core temperature over splits

Run

Four loops with nowhere to hide

  1. 0 km–10.5 km

    First loop toward Tulip Rotonda

    Open conservatively in full tropical heat

    The run's mostly flat terrain offers no shade and no natural check on pace, in conditions the organiser itself calls something you have to earn. Start well under the pace the flat road invites.

    • Take aid at every station from the start
    • Hold effort, not pace, from the first kilometre

  2. 10.5 km–21 km

    Second loop past Bago Aplaya Esplanade

    Use the turnarounds as honest heat checks

    Reaching the KM 5.5 and KM 10.5 turnarounds a second time, reassess pace against how the heat actually feels, not against the flat course's reputation for speed.

    • Reassess goal pace against the heat
    • Cool at every aid station

  3. 21 km–31.5 km

    Third loop, peak heat

    Protect core temperature over splits

    This is where extreme heat and a flat-but-demanding course combine to punish an early pacing mistake most. Ease pace before form breaks down.

    • Use ice or cold sponges at every station
    • Keep drinking on schedule regardless of pace

  4. 31.5 km–42.2 km

    Final loop to the finish

    Spend what honest heat management left you

    The finish at Bago Aplaya Esplanade's service road rewards a day paced to the heat rather than against it, an IRONMAN story genuinely earned.

    • Decide the finish honestly
    • Keep hydrating even in the closing kilometres

What I would keep an eye on

There is no useful 2027 forecast this far out. For now, past race dates give us a point of reference. Closer to the race, the forecast will tell us whether the plan needs changing.

05 Method

What goes into your range

Your CSS, FTP, weight and run threshold create the first range. Open-water, bike, run and execution evidence can replace broad assumptions. Course data and the historical conditions baseline shape every simulation.

Confidence is built from four inputs

How the model works

It starts with the targets in your Race Card, then samples the parts of a full distance that vary: open-water pace, transitions, bike speed at the planned power, and the drop in run performance after the swim and bike. Repeating that calculation produces a likely range rather than a single heroic number.

The current time calculation uses this race’s published distances, or standard full distance distances where none are published, with the available course headings, elevation and exposure evidence. Weather scenarios vary temperature, dew point, wind, gusts, rain and water conditions together. Unknown route detail stays visible as uncertainty rather than false precision.

It is not predicting your exact finishing time, placing, or race-day weather. It answers a narrower question: given the plan and the information we have, what range of day is plausible, and where is the uncertainty coming from?

Confidence is not a permanent “low”. It is recalculated across four separate inputs:

  • Your evidence: consistent inputs and recent race-like swim, bike, and run results.
  • Bike setup: measured or specified aerodynamics rather than a broad prior.
  • The course: verified distance and route character, including elevation and technical sections.
  • The conditions: a current forecast is more useful than a historical comparison.

It starts low when those inputs are broad. It can become moderate or high as the evidence improves. A narrower range means better information, not a guarantee.
