Any chance of getting an option to build a training plan in a “Sand Box”? (I think that’s the term) I built my training plan for the year with my (with my known) events, and all looks good. But, say something changes between events. It would be nice to see if I made changes to the events like changing discipline, adding events, changing dates , and or changing from say an B to an A event would do to my plan without it actually touching my current plan. I have tried this in the past and my calendar got pretty messed up…hence why I’m asking ---

Hey! I think you’re asking for visibility for a history of the ways in which you’ve adjusted your plan? ---

Ivy I think the OP is asking for a way to see what changes may take place to a plan, in isolation, without having to delete it first. Or at least some ‘undo’ function ---

YES! I had this same thought the other day. @IvyAudrain not so much looking at past plans, more like a option to say, “What would my plan look like if I went from mid- to high volume” or “How would my plan change if I switched it from crit to road race.” or (as OP asked) “What would happen with my plan if I switched my A and B events.” In my (albeit limited) knowledge of TR I don’t know of a way to do this without totally changing your plan and messing everything up. Maybe a “preview” feature when making changes to a plan is another way to solve it? ---

I think we used to be able to go to plan builder and preview (or build) a new plan (different dates, hours, speciality etc) but now there is validation preventing you from doing this if you already have a plan in place with overlapping dates. It would be nice to be able to preview a new plan again without having to delete the existing one first. ---

Yeah, the Preview is possible when adding new plans. Not sure what happens with trying to edit existing, but may be limited or impossible. ---

This is something I would like as well. My current workaround is to build a new plan in the future with the changes I want, and then look at what the plan recommends at the same time from event. Not sure if that makes sense, but basically if I am three months out from my A event, I will make a new plan that starts at the end of the old plan, with my updated events distributed similarly over time (e.g. original plan started 6 months before A event, then new plan I want to test has an arbitrary A event 6 months from start date), or with the events removed, etc. Then I look at what the plan recommends 3 months out from my A event. Kind of cumbersome, but it works for now.
