Judging from your posts, you probably want to actually go over the materials, not just a graph you got from somebody, because there is a lot more to it. As an example, if you read Angella’s book, you can see her routinely hitting >4000m/wk of tempo, even having multiple individual sessions over 3000m a week. Since you say you are training strictly “CFTS”, then something like this could be useful to know.
