to track and back, 4 x 800 @ 3:20 or so. hot and humid, tried to run relaxed like yesterday but a little harder @ this speed. This is the ramp-up to a stout speedwork regimen with times geared to a sub-20 5k. Can't happen if you dont give it a shot.
Did 4 instead of 5 because of the iffy air quality, supposed to get better in a couple of days so hopefully will hit it harder then.
