Each for time:
Run: 8x 400 m
Rest 2 mins between efforts
Often when people want to get better at running, they think more is better; that more volume will get them more proficient. Unfortunately, the opposite tends to be true. Going from no running to pounding the pavement for several miles at the time is hard on your body and likely won't lead to better technique.
A WOD like today's, however, will get you an opportunity to improve quality of movement while improving your cardiovascular endurance-- a win-win!
