01 Race Card
Your first range uses conservative assumptions. Add optional evidence to make it more specific. It is calculated in your browser and saved only on this device.
02 The course
You swim in the warm, clear waters of the Arabian Sea at Qurum Beach, ride a challenging city route past Muscat's iconic landmarks, then run three loops through Qurum Park. Ride the city bike as one steady effort and the run stays available.

Three loops through Qurum Park reward legs that rode the city bike evenly rather than surging at every landmark.

03 Race plan
One job for each part of this course. The distance markers tell you when the job changes. The course tells you why.
Swim
The calm sea swim rewards an honest, controlled opening.
Bike
The landmark-lined route tempts chasing the scenery. Hold one steady effort instead.
Finish planned nutrition and hold effort before the three-loop park run.
Run
Let the first loop through Qurum Park feel easy, not fast.
Repeat the first loop's effort rather than letting it drift.
Only progress on the final loop once the first two have held together.
04 Race week
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.
A race-day forecast is not meaningful yet; check back closer to the event.

05 Method
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
It starts with the targets in your Race Card, then samples the parts of a 70.3 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 70.3 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:
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.
