Difficulty: Moderately challenging
Things You’ll Need:
Step1
Start with Samuelson's beginner's version. Run fast for 400 meters (1/4 mile), then jog for 200 meters (220 yards), and follow with a recovery jog or walk.
Step2
Repeat the beginner's sequence three or four times.
Step3
Try sharpening intervals. Samuelson runs 400 meters, with a 200-meter recovery. Repeat this sequence five or six times.
Step4
Try 400-meter interval repeats at a set pace. Save strength to finish the last several intervals faster than the first few. This prepares you for finishing strong in a race.
Step5
"Finish the workout with something left over," suggests Samuelson. "Too many runners leave their best racing on the track or roads when they push too hard in prerace workouts."
