Could this be of benefit to the recreational runner? Not double threshold sessions, but two threshold sessions each week, dropping the faster work? Only introduce the faster stuff later.
I’m a broken record on this, but if you want to apply this to a recreational runner the best place to look is at the Ingebrigtsen older brother Kristoffer. All his training is on Strava
He does the same weekly schedule but only 1 run per day
Tues- threshold fartlek
Thurs - threshold intervals
Sat - longer threshold intervals
Sun - “long” run
You can look at what he’s doing now and be like hold sh*t that’s a lot. But if you go back a year, he has gone from 1:29 to 1:15 in the HM and probably will drop a couple minutes again whenever he runs another one. The progression has been very gradual and most weeks he does the same thing for several weeks in a row before bumping the pace or volume. You see almost no progression over a month or 2, but after a year he is doing WAY more and WAY faster.
My guess, the faster work is considered unnecessary for older or less developed runner as it is higher injury risk. There is so much aerobic development an adult recreational runner can have before speed is the limiting factor.
