This tool helps you calculate your estimated time to climb the Alpe du Zwift based on your power output and weight.
How to Use the Alpe du Zwift Calculator
This calculator helps you estimate the time it would take to climb Alpe du Zwift based on several input parameters:
- Weight: Your body weight in kilograms.
- Bike Weight: The weight of your bike in kilograms.
- Average Power: Your average power output in watts.
- Coefficient of Drag Area (CdA): A measure of your aerodynamic resistance.
- Coefficient of Rolling Resistance (Crr): A measure of your rolling resistance.
- Wind Speed: The speed of the wind in meters per second.
- Air Density: The density of the air in kilograms per cubic meter.
- Grade: The average gradient of the climb in percent.
Simply enter your details and click “Calculate” to see your estimated average speed and climb time.
Calculation Details and Limitations
The calculator uses the following formula:
- Considers the sum of user and bike weight.
- Accounts for aerodynamic drag, rolling resistance, and slope.
- Estimates speed based on the balance of forces acting on the rider.
Limitations:
- Assumes constant average power output.
- Does not change variables dynamically during different segments of the climb.
- Wind speed is assumed to be constant and coming head-on.
