Congrats! Someday I hope to understand why folks happily run 26 miles without some menace chasing them. I was a sprinter in track so anything longer than 400 meters is beyond my scope of comprehension.
Well, if you're in DC or some other megalopolis, you can run 26 miles faster than you can drive it, and a lot cheaper too.
Seriously, though, it's just a good way to get away from things and focus on the basics for a while.
