Go speed racer...

Just like my last run, today I alternated walking and running every 0.25 miles.  I always walk at 4.0 and for my first mile I ran at 6.6, second mile at 6.8, and my third mile at 7.0.

I noticed my running posture changed as my speed increased, even though I did not strain to run at these paces.  I also have caught myself on several occasions, mainly when returning to a walking pace, hanging onto the treadmill rails. Each time I caught myself I had to remind myself:

DON'T HANG ONTO THE TREADMILL!!!
