Chances are that your school’s campus has either an indoor or outdoor track (or both!). Most campus tracks measure in at 400 meters—which is absolutely perfect for this interval running workout!
If you’re looking to get faster and stronger, you should warm up with two easy laps, which comes to about half of a mile. For the interval workout, run just below your maximum sprint effort for the full 400 meters (so for one lap around the track), then jog or walk for two minutes and thirty seconds. Repeat this process up to eight times for maximum results, then cool down with two more easy laps. After a few days of this interval workout, you’ll beat your personal record in no time!
