Run 3 miles. If so, be sure to run at an easy pace. Don't hesitate to do some walking.
Today is a recovery day.
Run the fast repetitions at about the pace you would run 800 meters. While interval training is best done on a track, you could also do this workout on a golf course fairway or on any straightaway. If you're too tired to run today, it may be because you trained too hard yesterday. If so, you need to be more moderate about your training in weeks to come. You may experience some muscle soreness today, particularly if you're not used to running fast 200s.
