If you can run 2 miles in 14 to 16 minutes, that is cool. However, don't place too much emphasis on this as this type of running is only a part of the whole fitness picture. Coaches, be aware it doesn't take long to tire kids out, so make it quick and intense and get them outta there. Build slowly and gradually. Perform once a week max.
Sprints are all out.
Remember to warm up and cool down thoroughly. Sprint all out, jog or walk back to start, and adjust if necessary. Take 1-2 minutes in between yardage changes. Up and back, up and back, up and back, stop. This equals one Stinker.
