Bike power to finish 

How many watts do I need?

By inputting course details like total climb, elevation, and CdA, this calculator estimates the necessary wattage to complete a bike course within a desired time. This precise tool enables cyclists to gauge effort and strategy based on specific race metrics.

Another calculator can help estimated CdA (or aerodynamic drag), as for Crr (rolling resistance) we recommend either using the default value or looking online and searching for specific tyres, and pressure.

How to use this calculator 

input all fields and desired finish time

Get necessary gross avg power to achieve

this works pretty well on long courses, as everything averages, and works well on short course because there are less external pacing strategies.

This will not work well in draft legal race
