Peaking also involves having the proper amount of races at your specialty distance under your belt. Most American post collegiate runners don't race often enough.
so kw and danimal do you think this approach (of keeping rep speed and session volume constant and having rest be the variable to change) is a good idea?
once again example being
6x300 @ 42-43 (season goal pace)
starting with maybe 3 minutes rest and working progressively until 45 sec. rest is reached
Well I think it depends on how you are adapting. If going that route I would probably do 20s every 2 weeks. I would also test to evaluate where I stood, doing a max effort at the end of every 2 weeks to see how much adaptation occurred. If you haven't adapted, changing the recovery interval is a bad idea.
i could agree with that, i think races will be the max efforts to show my adaptation. I've planned it out where i have 2-3 weeks to "spare" keeping the same recovery interval and still making it to the end goal of 45 seconds, in case the linear progression isnt really working out, so i could plug those in wherever i stagnated.
