AM - 10 miles this morning without eating breakfast, which pretty much ensured I would be burning mostly fat on this run. Ran 4 miles to the HS track, average pace of 7:53/mile, then did total of 3 miles on the track. First two were average of about 7:30/mile, and the last one was about 7:15. Then ran back via a different route. By this time I was really feeling the effects of not having eaten anything, and felt like I was just plodding along. I decided that it would be a good idea for me to push the last mile to work on improving my fat-burning capability at faster speeds. Slowly increased speed from 7:55/mile or so to about MP effort with a mile to go. Last mile in 6:47. It was pretty difficult, both to maintain turnover as well as from a cardiovascular perspective. We'll see if I get in any more miles today. I am still kind of sore from volleyball - mostly either my piriformis or my gluteus medius on my right side. Stretched it out last night, will stretch some more today. |
