What is the 80/20 rule for 5K training?

The 80/20 rule suggests that 80% of your running should be at an easy, conversational pace, while 20% should be at moderate to high intensity. For 5K training, this means most runs build aerobic base at a comfortable speed, while shorter sessions include intervals, tempo runs, or race-pace efforts to develop speed and lactate threshold.
