Enter your rider weight, average power, and gradient into the calculator to determine your estimated time for completing the Alpe du Zwift climb.

## Alpe du Zwift Calculation Formula

The following formula is used to calculate the estimated time to complete the Alpe du Zwift climb:

Estimated Time = (Weight / Power) * (1 + Gradient / 100) * 30

Variables:

- Estimated Time is the time required to complete the climb (minutes)
- Weight is the rider’s weight (kg)
- Power is the average power output (watts)
- Gradient is the slope of the climb (%)

To calculate the estimated time, divide the rider’s weight by the power output, multiply by the gradient factor, and then multiply by a constant for time estimation. This simplified formula provides a rough estimate for the climb.

## What is Alpe du Zwift?
