Perhaps I am confused, but you are outlining a process totally different from the actual “Alternates” process TR created and documented.
Have you tried that or found it not to work? You can alter Duration (time) through that process.
Your ideal (setting time limits) is something TR wants to do as mentioned in this Feature Request and the podcast via Nate. But it’s not part of the process now. So using the Duration side of the Alternates tool/process is the easiest option available at this time.
It looks like alternates are now available in the web browser version! I was pretty excited to find this since I’m just starting a LV plan but will likely move the 1 hr to 90 min workouts as my schedule allows.
I should add…the “replace” button is grayed out because I didn’t select one of the alternates. It works as expected once a selection is made.
I’ve been on low volume plans for the past three years and it’s worked really well, I generally approach 300w FTP in the summer, and at about 70kg, that’s comfortably 4wkg.
However since my 3rd child arrived in December, my evenings have been constrained (this child screams when not being held). So I have maybe half an hour of riding I can do perhaps four times a week during my 1hr lunch break.
It’d be great to slot in my available time into the calendar, and for the programme to give me a plan built to make best use of it.
Yes please do this, as I can do a little more than the low volume plan but not always do a 1.5-hour ride on the weekend, would much prefer to set something like 5 hours and let Plan Builder do its thing as opposed to the 3.5 hours but then have 1-hour workouts instead.
I know I can use TrainNow or supplement workouts with this, but it is not as fluid for me. I just wish to have a plan and follow it as best I can.
