Ugh!! I just want to do YESTERDAY's training run TODAY.

I have never been able to do it after the day it was scheduled but if this works please reply back because it would be of great help to many people. This is a huge fault in the training programs, it should be easy to resechedule missed workouts because honestly after having done a few of them I don't see that it is really that personalized, more so that it is a template with a few different versions for variations. 

UPDATES!!!    10 JUN 2024

1.  @SEILOGRAMP - Thank you so much for the link.  Unfortunately none of the work-arounds actually work, BUT your link showed me several other forum posts on the same topic.  This is a design flaw that has been around for years, but Garmin apparently doesn't know about it?  I'll submit a bug report.   p.s. I did actually search for about 20 minutes, and never saw your link, but it was great.

2.  @4480375 - Spent all weekend trying different work-arounds, and none of them let you move a coached activity forward.

3.  @Everyone Else - So far I've tried the different tricks (from other threads) of pausing the coaching, changing the time and date, changing the scheduled workout days, editing the activity from the watch face, etc.  Nothing works.  The only thing that actually "works" is to look at the training that you missed / skipped, then manually re-creating it online or in the app and just choosing it as you would any other built-in activity like "Walk".   Of course then it doesn't show up on your training record for the event you're training toward.   The "pausing" trick only seems to work if you've built a training plan manually, but it does NOT work for "Garmin Coach" plans.  Also, as some users point out in the links, the "recalculating" that your coaching plan sometimes does won't really change the workouts at all!!!  It just moves the dates around if you reschedule, but there is no "smart" recalculation about distances, etc.  

4.  @GARMIN - WTH?  A user can click on a FUTURE activity, and then click "reschedule", but cannot click on a PAST activity and click "reschedule"   Geez.  Just add this one feature.  Look at the links below.  People have been complaining about this for YEARS.  

5.  @ANYONE - Links if you are interested:

It really is frustrating, I have done several of the plans and never been able to complete every run just because of circumstances, not feeling well that day or forgetting to move a run. I really don't believe that the plans are customized at all and that the baseline run has no real affect on the others, I have paused plans and they have just started back up on the week that it would have been in the plan not where I had paused. It seems to me, and I am not a software engineer so know nothing of how it works, but if I can reschedule future runs, it should be easy enough to reschedule missed runs as well. 

Garmin has a terrible habit of ignoring complaints and requests about software issues for years, there are many examples throughout the forums to illustrate this. Just one example - I bet you have a cross-country ski FTP value even if you have never been cross country skiing.
