A model, not a measurement. What it can show depends on the numbers above — what you typed, and what your files recorded — and on assumptions this page states; anything it cannot stand behind says so rather than drawing a tidier line.
Each piece named by what the ground is: the climbs, the flats and the descents.
| Piece of road | Length | Slope | Rise |
|---|---|---|---|
| Flat, 18.8 km from km 0.0 | 18.8 km | — | 30 m |
| Climb, 1.0 km at 3.0% from km 18.8 | 1.0 km | 3.0% | 31 m |
| Flat, 11.5 km from km 19.8 | 11.5 km | — | — |
| Descent, 1.1 km at 2.7% from km 31.3 | 1.1 km | -2.7% | — |
| Flat, 29.5 km from km 32.4 | 29.5 km | — | — |
| Climb, 1.0 km at 2.7% from km 61.9 | 1.0 km | 2.7% | 29 m |
| Flat, 11.9 km from km 63.0 | 11.9 km | — | — |
| Descent, 1.1 km at 2.5% from km 74.9 | 1.1 km | -2.5% | — |

How the road was measured
The length is measured along the course file's own trace, because the mapped roads covered too little of it to measure along. Expect it to be out by as much as a GPS trace usually is: a few tenths of a percent.
The climbing is read off a terrain model of the ground, averaged along the road, rather than off a barometer, which cannot tell a change in the weather from a hill. The file's own altimeter said 482 m, near enough the same road.
The course as described from the course IRONMAN published for 2025. watts & time is not connected with the event or its organisers; a course changes from year to year, so check the current one before you plan on it.
91.4 km with 342 m of climbing, in 2 climbs. The distance is measured along the course file's own trace, because the mapped roads did not cover enough of it, and the climbing is read off a terrain model of the ground rather than a barometer, which drifts with the weather, so a head unit will often show slightly different figures.
In the order you meet them: Climb, 1.0 km at 3.0% from km 18.8; Climb, 1.0 km at 2.7% from km 61.9.
That depends on you, so the page does not guess: open the course in the predictor. Set your weight, the power you will hold on each kind of slope and the position you will ride in, and it answers with the time and the band around it, climb by climb. Nothing to upload: the course is already there.
