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 a flat one-loop lake course in the Landa Provincial Park, ride one scenic 90 km loop through the Álava region with only small gradients, then run two flat, fast loops through downtown Vitoria-Gasteiz to a finish at the historic Plaza España. Nothing here is technical, which makes your own pacing discipline the entire race.

90 km
Small gradients through scenic Álava towns and a Camino de Santiago section make this an easy course to over-ride if you chase the scenery instead of your number.

21.1 km
A flat, fast two-loop run to the historic Plaza España rewards a bike that was paced rather than raced.

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 flat provincial-park lake gives calm water and simple sighting from the first stroke.
Bike
The gently graded roads through the Álava region and the Camino de Santiago section make it easy to ride harder than planned.
Hold effort through the remaining loop and finish your nutrition before two flat city run loops.
Run
Let the first loop through downtown Vitoria-Gasteiz feel easy, not fast.
Only progress once the first loop has held together, saving something for Plaza España.
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.
