01 Race Card
Four current benchmarks are enough to begin. I combine them with this course and 500 plausible race days.
02 Read the course
You swim a single 2 km rolling-start lap in the Arabian Gulf from the Lusail Ferry Dock, ride four identical 20 km laps of Lusail's closed urban streets, then run three identical 6 km laps through Lusail Plaza and Boulevard. Every discipline here repeats the same short loop several times, which makes this one of the most self-revealing courses on the tour: the fourth bike lap and the third run lap show exactly what the first one cost. Let the course set the context for your effort.

Three identical laps through Lusail Plaza and Boulevard give three honest checkpoints on whatever the bike left behind.

03 Race decisions
Each phase has one clear job. The course tells you when that job changes.
Swim
Athletes enter the water every couple of seconds rather than all at once. There is no gun to sprint off, so settle into your own rhythm from the first stroke.
Bike
The closed Lusail streets feel fast on a fresh first lap. Set a wattage you can hold identically three more times, not the number that feels easy right now.
The middle two laps are where small drift compounds unnoticed. Compare each lap split to the first rather than only to how the legs feel.
The final lap is identical terrain on tired legs. Finish it at the same number as the first three, then let T2 be the transition, not the recovery.
Run
A flat, three-lap run gives an honest early read. Run the first loop a shade easier than goal pace.
Passing the same landmarks a second time tells you plainly whether the bike was ridden sanely. Adjust the plan honestly here, not on the last lap.
The final loop through Lusail Plaza and Boulevard is where a disciplined bike and two even run laps get to pay out.
04 Race-week review
There is no useful 2026 forecast this far out. For now, use past race dates to know what you may need to manage. Closer to the race, we can decide whether the plan needs to move.
A race-day forecast is not meaningful yet; check back closer to the event.

05 Confidence
Your CSS, FTP, weight and run threshold create your first range. Add evidence where you have it and the calculation reflects more of your actual situation. Anything still unknown stays visible, so you know what to revisit before race day.
Confidence is built from four inputs
It starts with the targets in your Race Card, then samples the parts of a T100 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.
The current time calculation uses this race’s published distances, or standard T100 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.
The calculation estimates a plausible range of race days and shows where the uncertainty sits. Placing, exact weather and your in-the-moment decisions remain outside the range.
Confidence changes as the evidence improves. It is recalculated across four separate inputs:
It starts low when those inputs are broad, then rises as the evidence improves. A narrower range means better information, not a guarantee.
