Here is the deal I am 39 years old. I am married with 2 kids. I was a solid runner 15 plus years ago. I have run sub 30 for 10,000m 4 times in college. At 32 I had to have an emergency angioplasty to open a 90% blocked LAD. I don't typically run outside, I usually only run on a Treadmill. Today I said screw it lets see if I can still hold sub 7:00 pace. I did a half mile warm-up and half mile cool-down. I managed 6 Miles on the track in 39:39.00. My splits were as follows:
Mile: 6:30.00
2 Miles: 13:17.00
3 Miles: 19:59.00
4 Miles: 26:47.00
5 Miles: 33:13.00
6 Miles: 39:39.00
Weather was windy humid and 82 out.
