Best way to "restart" a derailed training plan

Tough question to answer but I would suggest starting off with the first week to ease back into things, skip the 2nd week and go onto the 3rd week, skip the 4th week and onto the 5th week. Somewhere in there you should have a recovery week where you will want to do and then from there jump up to where you are supposed to be at for your training. 

Or you could just start out from week 1 again and towards the end of your training jump up to match closer towards the end of your training. The main thing is to not over do it getting back to training.

Really try to make sure you do the recovery weeks as those are beneficial to give your body a chance to refresh and prepare for the next build phase.

Here's what I would do:  Start where you would be now.  If it's too hard (accepting that getting going again might extra uncomfortable) then reevaluate.     A training schedule off the shelf has a bit of arbitrariness to it anyway. 

I suggest starting back on week three of the plan and see how you feel.  If you feel good, then jump ahead to where you would have been,  if not then just continue from that point.   You still have a long time to get ready, so I wouldn't worry about it too much at this point; most training plans have some "padding" built into them.  Stuff happens and you'll probably have some other conflicts and setbacks along the way.  Learning how to deal with adversity and interuptions to your training are just part of the deal.

Good luck with your training.

I'd do this too, but perhaps you could cut it down by 25% or so..and ease into it.

You're still at the early stages of the training period so just don't get sick again ! ;-)

I concur

either switch plans, or go from what the plan says and complete WHAT YOU CAN
