Continuing the run

Ran/walked for 2 miles in 24 minutes today at the Gym. Started with a half mile run at 6 mph, walked 1/4 mile at 4 mph, ran 1/4 miles at 6 miles per hour, walked another 1/4 miles at 4 mph and finished off with a 3/4 mile run at 5 mph. Wasn't motivated to go for longer run; body was too stiff! Finished with 5 minutes of stretching.
