I need to do the same moving some weeks as I was down for the count with shingles etc. I saw this on another post in Uphill Athlete:
Thanks to Carter Wehrer at Training Peaks here is a simple way to bump/shift a week or whatever timeframe you want. I wanted to repeat week 7 of the 24 week program and the instructions below worked perfectly, simply and quickly. I do have the premium account not the free TP account.
From Carter at TP:
To repeat Week 7, you will want to shift weeks 8-24. Please follow the below steps to make the necessary changes:
• Select the date header for the first day, Monday, of week 8 (the 3 dashes next to the date)
• Hold ‘Shift’ on your keyboard
• Select the date header of the final day of week 24 (the 3 dashes next to the date)
• Weeks 8-24 should now be highlighted and a selection popup will come up
• Either Shift to new date, or cut/paste
• Once 8-24 are moved, you can then copy/paste week 7
