Ran on the Provo River Trail between the Geneva Road and the Utah Lake. Met a new friend - Corey Osborne during warm-up.
Then did the same 5 mile tempo as Saturday. The purpose was to build fitness while measuring recovery from the marathon.
Got 28:32.7, mile splits - 5:31 - 5:42 - 5:49 - 5:48 - 5:43. Out 14:07, back 14:25.
First mile felt very easy, and I thought that I'd be able to keep that pace all the way, and maybe even speed up a bit at the end. My legs felt strong. Then on the second mile they began to lose power, and got essentially back strengh-wise to where they were Saturday. I have observed this phenomenon before. Shortly after one punishing marathon or a set of two or more marathons done back to back, the legs feel normal for a little over a mile, and then all of a sudden just quit. You suddenly slow down about 20 seconds per mile, and then it does not get any worse.
Well, at least I was able to do a good mile, something that did not happen Saturday, and the overall time was faster, so the recovery is slowly taking place.
Ran with the kids, and jogged some more in the evening to make the total 15 miles.
However, I think this drastic slow down sheds some light on my slow downs in 5Ks. I believe the limiting factor is of the same nature, it just happens at a slower pace when the muscles are still partially torn up from the marathon. Interestingly enough, Dallen seems to experience a similar problem.
