5 mile: 55:41
10 Mile: 1:54:55
20 Mile: 4:28:32
So, as you can see, I was on track at first -- averaging 11 minute miles, which was about what I was hoping for -- but then, things started to deteriorate. The second half of the marathon took one and a half times longer than the first half, and it's quite clear from the time that what I described at mile 20 was pretty much a break down of all aspects.
Eh, I still finished.
However, this is precisely why I want to do another one sometime later in the year (by then, hopefully, the soreness will have dissipated). I want to do it better.
