Just saw this video by fellow Dirigo runner Scott Douglas over at Running Times, where he details how and why to do a Diagonals Workout at least a few times per week:

Diagonals are a relatively low key type of exercise that are focused on leg turnover.

You just need to find a field, kick off your shoes, and do a combination of running and jogging for a set duration of time. Generally speaking, you will jog along one edge of the field, run diagonally across to the opposite corner, jog along another edge of the field, and then make another dash to the opposite corner once you’ve reached the end of that edge, as shown here:

Try working them into your regular routine and then come back and comment on your results!
