That's three hours, fifty minutes, and thirty seven seconds.
My sister ran in the Philadelphia Marathon today. I know what you might be thinking: "Didn't she just run a marathon a few weeks ago?" Yes and I wrote about it here and here. So what's another 26.2 miles, right? The good news is that the November weather was more conducive to running to Timbuktu and back and her time (3:50:37) qualified her to run in the Boston Marathon (again) in 2008.
There's not a lot of things that I would do for almost four hours straight (other than sleep). Congratulations Janet.
