Do you use a garmin? As soon as I used the code I received from coach AJ for TrainingPeaks, it asked me to sync my garmin with it. Once a I am done with my workout and I hit save on my watch, it automatically syncs it with training peaks and it shows my planned workout and my complete led workout side-by-side.
You can also enter or manually edit a workout as well, but I highly recommend syncing your training watch as it is much easier.
Hope that helps!
