Hi Zach .. no ... run 2 days then Rest 1 day .. then run 2 days and rest one day
Session 4 is called fartlek
, and you run 4 mins at a perceived pace you think you will need to run the 3 mile in. This is to develop pace judgement. You then run for 60 seconds easy between each 4 minutes run at pace
so 5 times you run 4 minutes fast with 60 second easy jogging in-between.
If you run too fast, too soon you will get tired too quickly and will find the session too difficult, this will teach you to pace yourself without going too quickly at the beginning, with time your pace judgement will improve
Please ask further questions where necessary
