ZwiftPower Results

Variability Index. A calulation of how even your power was. A lower number is more of a TT effort, while higher suggests many sprints with plenty of rest. It is simply your Normalised power / Average power.
An estimate of the power you could achieve if your power had remained constant.
Avg 20m
If strava data is not available this is calculated from your average power using a modifier percentage based on time of effort
This is the lowest weight you had during the race.


ZPower riders cannot win in any category.

Some races will require a HRM be used. There are 2 options available - only those with a hrm can win each category, or all riders require a hrm

Most races enforce a 5wkg rule for all categories. Any rider exceeding this will be removed from results if not approved.
