I'll be starting from Monday I think, I struggle to do the week plans though as I commute 30+miles 5 days a week in addition to the training, plus I have mid week commitments.
I'm rearranging my start times though so I should be home earlier and able to get on.
Last year around April my FTP was about 300, last week zwift re-estimated at about 350, but I put that down mostly to commuting the extra distance with one or two high intensity sessions a week through summer. I'd like to raise that to 400 this year by following a plan properly. I'll probably need a new trainer though as I'm already able to sprint past 900W, and some of the intervals look like they may go higher.
I also need to lose some weight, ideally around 10kg to get to around 84kg.
So that's my plan, albeit late to start.
