Hi Lauren, yes there is. I shifted my entire plan ahead by one day.
How you do it: in your training peaks calendar, Hover over the grey header bar of the first day you want to shift; the grey bar that has the day number on it (i.e 10 for the 10th of january). When you do that, three lines show up in that bar. Click on those three lines (but not the options that show up, just the lines). Then select the LAST day of the range you want to shift. You will see the entire range is selected and you have the same options, one of which is “SHIFT”. Click on that, and select “-2 days” to move everything up two days.
Maybe in your browser it’s easy to do the whole set at once. But I would try just one week first, so that you can make sure it’s all highlighted and to see how it works. Then, do the rest. On my browser, it seemed to lag when I scrolled and tried to select the entire 12 weeks and I wanted to make sure i had everything, so I did it in small batches (2-3 weeks selected, shift by -1 day to move them up, then go further in the calendar and grab the next 2-3 weeks and move those up, and so on).
If you don’t want to shift your ENTIRE calendar like I did, then you can also just switch your day off (ie. maybe your sunday with your friday). To do this, you can just drag and drop workouts from one day to another – i.e. drag “DAY OFF” and “OPTIONAL YOGA” to Friday, and drag “AEROBIC DAY” and “MOBLITY” to Sunday.
