Wow, another tough one. I tell ya, those extra 30sec per run makes a huge difference, but I did it! Part of me is thinking to re-do this week, but we'll see how I feel on Friday's run.
On the second run I was going faster and I think that's what took a lot of my energy. I need to keep a steady pace and work on speed later. Keep working on my form.
Using Ullrey's podcasts, I forget that he is not a barefoot runner, nor does he wear minimalist shoes. Right before the 2nd run he mentions landing on the heel and not on the toes, and all I could think of was OUCH! I don't land on either.
