if you have ever run a marathon, what was your time, and how did you feel you did. I ran my first one on Palm Sunday in St. Louis. did good the first half, then cramps got me. i had to walk the last 8 miles or so cause i couldn't run without my calves cramping. finished in 5:52 and change. pissed about it, cause i ran the first half in 2:18, and the second half in 3:30. anyone else?
