The endurance training is meant to keep you running at a stable speed without taking any sort of brakes from this. If you are still at a beginner level (5K) then you should be looking at around 30 min of running. When you get to the level of going for a marathon then this should be at around 2,5 – 3 hours at a steady pace.
