You and this race
Sharpen your range with more detailOptional. Recent swim, bike and run results, equipment and transitions.

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 Sir Bani Yas actually gives you

You swim one protected loop off Sir Bani Yas Island's southeast coast, ride the island's traffic-free ring road with real interconnecting climbs up to 100 metres, then run a flat, multi-loop coastal marathon through a race village built for atmosphere. The Gulf heat and the bike's hidden climbing are the two things this mostly-flat-looking course actually asks of you.

Swim

3.8 km

Protected Sea Loop

Setting
the Arabian Gulf, southeast of Sir Bani Yas Island

A protected loop off the island's southeast coast, sheltered from swells, gives a calm, controllable start to a demanding day.

Bike

180 km

Island Ring Road With Interconnecting Climbs

Setting
the full ring road of Sir Bani Yas Island, closed to traffic
Elevation
1228 m published profile difference

A closed, traffic-free island ring road with genuine interconnecting climbs to 100 m makes this a course where pacing the climbs matters more than the mostly flat overall profile suggests.

Run

42.2 km

Flat Coastal, Multiple Loops

Layout
multiple loops
Setting
the race village and coastal roads of Sir Bani Yas Island
Elevation
100 m published profile difference

A flat, multi-loop coastal run through the race village puts a supportive crowd within steps on every loop, which cuts both ways for pacing.

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

Settle in protected water

  1. 0–3800 m

    One protected loop

    Use calm water to save something for the heat ahead

    A single loop protected from swells off the island's southeast coast gives a controlled opening. Settle into rhythm early; there's little here to slow you down.

    • Settle by 300 m
    • Breathe on a fixed pattern

Bike

Respect the climbs the ring road hides

  1. 0 km–60 km

    Onto the ring road

    Bank nothing on the flat sections

    The island's ring road is flat, smooth and fast, and it's tempting to treat every kilometre that way. Ride to your planned number, because the interconnecting roads ahead will ask for real climbing.

    • Start drinking early in the heat
    • Check power, not just speed

  2. 60 km–130 km

    The interconnecting climbs

    Pace the climbs to 100 m the same way you pace the flat

    The course's genuine elevation gain comes from roads connecting the ring road, reaching up to 100 m above sea level. Hold your effort ceiling here rather than reacting to how easy the flat sections felt.

    • Hold target watts on the climbs
    • Fuel through the exposed, hot sections

  3. 130 km–180 km

    Back around the island

    Arrive at T2 ready for heat and multiple run loops

    As the ring road closes the loop, shift focus to the run: a flat, multi-loop course in daytime Gulf heat. Finish planned nutrition and hydration before you're on your feet.

    • Finish the planned bottle
    • Front-load hydration before T2

Run

Use the heat, don't fight it

  1. 0 km–10 km

    First loops through the village

    Respect the heat from the first loop

    The run's flat, multi-loop course through the race village puts fans and hydration stations within steps, which makes it easy to ignore how hot it already is. Control the effort from the first loop.

    • Use every aid station
    • Check effort against heat, not just pace

  2. 10 km–30 km

    The middle loops

    Hold pace as the day heats up

    Daytime temperatures climb through the middle of the run. Hold your planned pace and lean on the crowd for lift, not for pace.

    • Reassess pace every loop
    • Keep fuelling and hydrating on schedule

  3. 30 km–42.2 km

    Final loops to the finish

    Spend what the heat left you

    The closing loops bring you back through the race village to the finish. If you managed the heat well, this is where you find out. If you didn't, protect the finish rather than forcing one.

    • Decide the finish honestly
    • Use the crowd for the final loop

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.

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.
