So, my run tonight... I did what was supposed to be 7 easy miles, but they sure weren't easy. Breathing was fine, just the legs didn't have it today. Anyways, 7 miles in the bank, a good stretch, 200 crunches and 3 x 12 girly pushups.
And my new pair of Brooks felt fine - even with the change from narrow back to medium width. I certainly felt the extra room the first few minutes, but it was fine. No blister issues. :-)
