I would like Import Exercise from other sources
website 8020endurance.com etc.

The ability to import an existing power profile (.fit, .gpx, etc.) from an existing outdoor ride to generate a 'real world' custom workout. At present, manually building a custom workout profile mirroring the actual noisy power data would be very time consuming – even with smoothing. This would allow me to match or train on my usual outdoor experiences while using my indoor trainer in the winter months.

I would like to upload workouts as a .txt or .zwo or .tcx or .csv file

TrainingPeaks simply needs to allow users to import a custom workout file (e.g., .erg, .mrc, and so on) by uploading or dragging and dropping into a workout as a planned/future session.

E.g., I have a custom workout in Intervals.icu, and rather than re-create it in TP for an athlete, I can just export from my Intervals.icu calendar and upload in TP.

Currently it seems like the only option is to re-create the workout in TP all over again.

This is absolutely critical. I am able to import workouts from multiple file types (.erg, .mrc, etc.) into a platform like Intervals.icu, yet this is still not an option with TrainingPeaks?

Ability to import a TrainerRoad training plan to the Training Peaks calendar

I just purchased a year of premium thinking this was already available as the workouts have an import button....
I just spend a couple hours recreating a week worth of workouts because they can't be imported.

Seconding ability to import zwo to the builder, and other workout file formats, without the need for third part apps.

In the Zwift platform there are so many workouts that import then directly to TP calendar would be great and a lot more easy to build a weekly calendar and everyday training workouts will be available on Zwift
