After some of my marathons, I treat myself to a nice dinner, or a new item of running gear, or a book I have been wanting, etc. I haven't bothered with the pics or the frame, but that's just me.
(Actually - thinking of books - I really enjoyed "My Life on the Run" by Bart Yasso. I don't know where you live, but I do know that Yasso is going to be at the Illinois Marathon expo on April 10th. When I got my copy at the USAF Marathon last year, he autographed it for me, which was nice.)
