Well, for sure I love what folks on the forum might suggest for a training block! (I love the forum even though I antagonize it all the time) but for this specific idea I’m more interested in what is TR suggestion for a good VO2 booster block or a good sprint booster block.
Just for a case where there is a few weeks in my calendar where I could throw in some sprint work…but would like to do it in a fashion that doesn’t let my threshold slide too much. Or something like that.
