3/16/12 (Friday) Run

Today I ran 20 miles in 2:32:20.  I ran the first five miles at 7.5 mph; 2^nd four miles at 7.7 mph; the 10^th mile at 8.1 mph; miles 11-16 at 7.9 mph; miles 16-19 at 8.1; and mile 20 at 8.3 mph, running the last .15 miles at 9.6 mph.  I felt really good when I was done; tired of course, but not exhausted.  I am not sure why my recorded time two weeks ago was 11 seconds shorter as this should have been a slightly faster run.
