In todays session, we return our attention to breathing and rate of perceived exertion - 
But, we also begin to look at foot fall. Which point of your foot is in contact with the ground. Are you heel striking or landing on the midpoint? 

In today's session, we are going to go a little longer in our working set - jogging for 20 seconds x 15 reps. 
If you are aiming to improve your 5k time and you want to work on speed, you can do this short interval session as a jog/ with a slightly faster run. Watch the video here for your warm up https://youtu.be/quLwOpP-as0
