For time

1600/1200/800/400m Run
8 – 6 – 4 – 2 Rounds of:
5 Chest-to-bar pull-ups
10 Push-ups
15 Air squats

Time cap. 45:00

Pace. The aim is to get through the workout at a pace where you don’t have to stop anywhere (except perhaps on the push-ups). It’s ok to start easier on the 2nd and 3rd runs but aim to get back to speed after about 200m latest. Steady work through the triplet.
Session RPE. 8/10, you should feel tired but not exhausted at the end of the workout
Intent. The running mixed focused conditioning sessions in this block will build your engine and specifically improve your running in workouts.
Adaptation. Improve your capacity around your lactate threshold (think: improve your long, sustained sports-specific performance) and running capacity in workouts specifically.
