Easy 2.2M in 17:00, or so I thought.
I used my new Nike+Sportswatch GPS today and stumbled upon another truth: the 2.2M route I've been taking all these years is really 2.15M, provided my Nike GPS is accurate. I guess I sort of knew that, but figured the effort is more like 2.2M than 2.15M given the hills. Yes, I am one for precision, so the difference between the two distances does strike me as noteworthy, particularly since the difference is compounded when I do multiple loops of the run.
2.2M--2.15M (beginning at back of driveway)
4.4M--4.25M
6.6M--6.4M (ending at back of driveway)
Going into Thursday's workout I thought I could break 55:
1st 150--19.8 sec
2nd 150--20.4 sec
last 100--14.5 sec =54.7
OR
1st 200--26.4 sec
2nd 200--28.3 sec = 54.7
However, after a lackluster workout, here's my possible reality…more than a half-second slower--
1st 150--20.1 sec
2nd 150--20.6 sec
last 100--14.6 sec =55.3
OR
1st 200--26.8 sec
2nd 200--28.5 sec = 55.3
