As the plan preview does not work for me personally, I have created a custom plan on TP and use Coachcat for feedback and to check on readiness. It would be great if there were another way to schedule future custom workouts than describe them in the chat and wait for Coachcat to schedule them. I have experienced problems with scheduling more than one workout this way.
Alternatively, it would be fine if my Coachcat/FasCat training plan would sync to TP, so I could know what is going to happen in the long run.
