Another marathon memento to put around my neck

The other day I saw a website that made necklaces for athletes.

I decided I HAD to HAVE a necklace in honor of the marathon I ran...2 years ago.

Isn't it spiffy?  You get to customize the charm piece with a map of the town you ran the race in.

My only question is.... Do I need 13 of them for each half marathon I've run?????
