You couldn't have kept going for one more second? :-)
I noticed that when I stopped, saved it, as I could never achieve that if I tried.
I ran a marathon in 2:59:59, and, as you might imagine, I was really trying not to add one more second.
Last time I ran the snowstorm 5k at Forest Park I did it in 29:59. That involved a bit of extra effort, too.
