How to run it
Warm up for 10 minutes, then run 4 x 8 minutes at threshold pace with 1 min of gentle jogging between, and cool down for 10. The short jogs let you hold threshold pace for longer in total than one continuous run would.
What it's for
Threshold running raises the pace you can hold before fatigue builds quickly. It is the pace of an hour-long race, and improving it helps at every distance from 5K to the marathon.
