How can I delete my sprint 60 days and older?

What are you trying to do and why?

In certain sprint I have a long list of my times I am only interested in the sprints that I done in the last 60 days

There are various apps you can use for this data.

Zwiftpower will show you your 90 day sprint that you have completed in the last 90 days. If you use Strava you can use this to show your best sprint within a time period.

We don’t remove your best power output in the game, so that will always show your best.

Thanks for your
