Here is a sample of the high level delta with the “Master” switch Off (top) / On (bottom).
I also swapped the order of the Thu & Sat workouts as I normally do:
The difference is swapping the Hard Sat workout for Endurance.
Next step adds “Masters” at the lead of all phases:
And jumping into the header for a phase allows selection / swapping between Masters and regular versions, apparently:
And after reviewing the main plan, I gotta say it looks solid overall. I do wish I had the option to set longer workouts on Sunday than the apparent max of 2 hours. I get it for indoor since most people won’t ride a trainer longer.
But even if if I swap to Outside, it keeps the 2 hour limit. I expect people would like the option to use longer workouts in these cases (at least I know I want them). I will just use Alternates for longer duration since that appears to work from a quick test. So perhaps the 2 hour limit makes sense and hits the widest range of users.
