or if you get sick and don’t do the plan or whatever life throws at you. you can make changes and the plan builder takes that into count and corrects from there?
Ok, this maybe a little OCD or a bug… 
When I originally used plan builder to map out my training plan I said I wasn’t training for any events at the time (I just didn’t have any scheduled but knew I would add some at a later date). Well that later date was yesterday and I discovered it wouldn’t recalculate my plan. Searching the posts I learned that I would need to delete the plan and create it with the new event which worked fine.
Now when I created the new updated plan I pre-dated the start to when I started the original plan builder plan and all was well, except it didn’t place the week # notations on the two previous weeks that were already completed, the notations started at #3 along with the “plan start” notation and went from there. It’s easy enough to move the plan start notation to the real start date (but if I’m telling the plan builder I started on x date why doesn’t the notation get added there instead of the day the plan was created? i.e. today) and why aren’t the previous # weeks notations also added. I manually added them back in as an annotation to satisfy my OCD but I was thinking this might be a bug?
I think plan builder doesn’t actually place anything in the past. It just ignores the first weeks it comes up with, and then starts ‘mid-plan’. It would be pointless (and a bit messy) for it to put workouts (and comments) in the past. And also technically, you didn’t start this plan in the past, you’re starting a new one right now - even if the first weeks were identical. (More commonly, people want to start in the past to account for any base blocks they have done, but those weren’t necessarily part of a plan).
I have this exact problem. In addition I have a “Base1” tag in the week starting January 6th as well (so I have two “Base1” tags). Any responses to this?
I understand what you are saying but in my mind if I’m telling plan builder to use a start date in the past then they should be notating those weeks as per of the plan IMHO.
Simple triathlon plan builder feature request, add plan volume selection or sport removal in the editing stage. My example below would be choosing the TR low volume bike plan, the high volume TR swim workouts, and it would import no run workout. Then users can add their own running plans. Obviously some may want to do the same with the swim etc, but this is just a thought.
This makes it so much easier to mix and match sport workload based on what an individual wants to improve on most, has time for (I can normally spare 15 more minutes to do the mid vs low volume swims), or injury recovery (ramping up running volume post injury at low volume runs)
It asks me when to start the plan, and I select December 2, but it starts it on January 2 anyways. Is there any way to add events without completing starting the plan over?
It’s working as intended, at least for the time being - @splash gave a pretty good explanation. Glad you were able to find a workaround.
The actual starting date is always going to be “today” if you select a start date in the past but the workouts you see will be different (e.g. if you select a start date a month in the past, a month’s worth of workouts will be “ignored” and you’ll start later in the plan).
If your existing plan already has events, adding a new event should cause you to be asked if you want to recalculate the current plan. If your existing plan has no events, you currently won’t be asked to recalculate - this is a bug that we’re aware of. If the latter is the case, you’ll have to add a new plan unfortunately.
Looking into this one.
Edit:
To update you guys, I figured out how to reproduce the bug and have created a formal issue for one of our engineers to look at. As an example, if you have your workout days scheduled on Mon, Wed, Fri and start your custom plan on a Saturday (after the first week’s last workout but before the next week begins, if that makes sense), you’ll run into this one. This would have happened if you guys chose the 5th (Sunday, “end” of week 1 as our calendar weeks start on Monday) as a start date, otherwise there may be a timezone issue going on that led to the plan “starting” on the 5th instead of the 6th.
My start date is January 6th, workouts on Monday, Wednesday and Saturday. Looking at the overview it says January 12th - August 22nd (my A race is August 15th) and looking at the base phase, it starts Dec 30th. All this seems a bit strange to me. I have attached three screenshots showing this. My timezone is Europe/Stockholm (Central European Standard Time).
I selected start date January 6th, with workouts on Monday, Wednesday and Friday. No end date selected gave me the issue, plan started on week 2.
When I selected an end date somewhere in 2021 all was fine. FWIW I’m in Europe as well.
+1 from me on this feature. I follow MV bike, HV run, and MV swim.
I have exactly the same issue and have already raised a support ticket on it.
Just hit something when re-doing my plan today:
At the ‘events’ page, I deleted my only A event so I could change it from a single day to a stage race. I After I added the A event back, the ‘next’ button was still greyed out, even though I now had an A event. Simply toggling the 'add openers …" button got the ‘next’ button to be available.
Is this still functional? We had a team training camp scheduled for January which I entered as a stage race of “C” importance since it is a ton of TSS on back to back days. I built the plan including it and A and B events later in the year. The camp just got postponed to February. I deleted the January event and created a new “C” stage race to account for it in February. However, there was no dialog box asking to “recalculate plan” Where do I find this?
Is the Plan Builder down? I just keep getting the beachball/velodrome forever.
Is there a way to add just swimming or just running events? I added triathlons as events and dropped the bike and swim to 1 sec durations, to try to make it a just run event, but it didn’t change the plan. Am I doing something wrong?
I found a way around it. I logged out and then logged in again.
I suspect that something was cached. I tested it a few days ago, without accepting the plan. Maybe it was trying to retrieve something or another.
Sadly, I don’t think so right now via the Plan Builder.
What you can do is add an “Other Activity” manually on the calendar for run, swim and ‘other’ as a catchall. But those are not ‘Events’ like the Tri stuff, so I don’t know if that really helps you.
Entering a BRM 600 (600 km) and allowing for 36 hours, I get a TSS of “-150” … a 600 is a tad more stressful than that 
Heh A hilly 1.75AAA BP of only 117km gives me nearly double that. (My effort was Tempo)
