I got into running via trail running and subsequently ultra running, which I admittedly still love. It's been about 5 years of steady-ish training, typically following a more-or-less marathon schedule with some longer weekends closer to races.
Of course the hard workouts in this sort of training (maybe 800s would be the fastest ever intervals) are still fairly slow and not really touching on top-end speed. I've decided that running fast is fun and I want to chase a fast 5k (current PR 16:48).
With all of the volume I've done (mostly averaging ~70mpw, some 90s in there) for several years, I should definitely be able to go faster than that @ 28 y.o.
Other than strides, what would be the go-to strategies/workouts/structure to focus on the 5k coming from a decent aerobic base, with the main goal of pulling enough speed out of my legs to tap into the aerobic strength? Just try to recreate HS XC?
