Notes
At the Silver Comet, doing 20 with last 4 at MP, with temp 70, dew point 69, TDP 139 = 1.028 * 10:17 = 10:24 and * 9:30 = 9:45.
So, for miles 2 through 16, I averaged 10:09.3 for pace with an average HR of 115.5
For miles 16 - 20, I averaged 9:17.3 with an average HR of 125.8.
Nutrition seems to be a useful thing. I had two overflowing scoops of oatmeal this morning and had lots of pasta and shrimp yesterday.
