Try adding Stairs to part of your running drills circuits to help increase your knee drive and force production that your foot puts through the floor. This in turn will help you run quicker!
Do 8-10 reps of about 12 stairs. If possible, have a short run up. Run the stairs at a good crisp pace and with accuracy. It’s important that the steps are not too high (6 inches is ideal) and not too far apart (you do not want to be ‘bounding’ up them).
Here is a video talking you through how to do them.
Have fun!
