I've downloaded a training plan, it's in my calendar. Great.

Swim, bike, run workouts are obviously divided into 400m of this, 200m of that, run 30mins @ pace etc.

Now in TP there seems to be no way to view the actual time taken (or any measure) on each workout step. Swimming is close because you hit the lap button, but it still doesn't align with the workout...you get a big list of splits Freestyle, 1, 2 etc. Largely useless.
Running does 1km auto laps, not related to the workout steps. Again, largely useless.
I guess you could faff around with the charts trying to select the right step...but really?

Garmin connect, free, does this very well.
