I'm following Jack Daniels' well known training book and working through the 6 week phases. It's fairly standard stuff: phase 1 is aerobic base building with some hills, phase 2 is short intervals and tempo, phase three longer intervals and tempo, then phase four is km reps at race pace. I'm now in the last week phase 2 and due to reach phase 4 in the middle of September, which was originally designed to get me in peak shape for some autumn and winter races, where I've got some goal PBs to shoot for. The problem is that the Great North Run in September has now been cancelled, and there's a lot of uncertainty about when we can race again.
How do the phases work in this limbo situation where we don't know when we'll be racing? I don't want to go back to phase 1 (easy aerobic base building) and then find races are starting up and I'm not up to speed. Equally though I don't want to get stuck in autumn repeating phase 4 (no intervals, just 1km reps at race pace) and lose the strength and speed built in phases 2 and 3. Is there an accepted approach to this? I've searched all over the web and read through Jack's book and can't find anything of help. My only guess really is to finish phases 2 and 3 in August and then go back to 2 again, then if racing starts try and rush through a mini phase 3 to get to 4.
Yes, I know I might be over-thinking this, but I just want to be the best runner I can be.
