Zwift Climb Tools & Calculators
Free tools for working out how badly a Zwift climb is going to hurt — before it actually does. One climb so far. It's the one everyone asks about, so it seemed a sensible place to start.
The flagship
Alpe du Zwift Time CalculatorTell it your weight in kilograms and the power you reckon you can hold, and it'll estimate how long Alpe du Zwift will take you — your w/kg, your time in minutes, and exactly how many more watts you'd need to make that time stick 90% of the time. It is, fair warning, a little rude about your numbers.

Alpe du Zwift isn't the only mountain in the game, and it won't be the only calculator here for long. Ven-Top, Road to Sky and the rest of the Watopia leg-burners are on the list — same maths, same cheerful disrespect, one climb at a time. Get the Alpe dialled in first; the others will turn up when they're ready and not a moment before.
