Here is the data from the Barefoot test on the 13th:
I was pretty spent for the last 2 intervals. I have to say I really didn't want to run the last 2 mile interval but was glad I did in the end. I got a great workout out of it even if the data was a bit inconclusive. It's skewed from going too hard for fitness and conditions on the first interval. I felt very heavy in the Brooks shoe I chose for the test. I has a lot more heel than my Mizuno's although most folks would call the shoe a racing shoe. The heel was noticable and really inhibited my foot strike making me work harder. I wonder if a better test of barefoot / shod would be to run the first one at my perceived 10k or even Marathon Pace effort shod and then follow barefoot with the same HR. I would get more consistent splits and could adjust for conditions by running by perception. You can see my recoveries were very long (especially after the first interval).
Today is a much needed day off and tomorrow I hit it hard again in Springdale Cemetery. My next long run will on Saturday be in sweltering Louisville, Kentucky! 15 miles of fun!
