I ran the half-marathon in San Francisco this past summer. It was amazing. Afterwards I wanted pictures to remember it by–specifically, pictures that had me in them to remember my experience. Before the race, MarathonFoto informed me that “you and your family will not have to worry about trying to capture your special race moments” because they would take pictures. Great! They neglected to mention those pictures would cost $40 each to download.
I liked the pictures, but that heads-up they gave before the race was slimy. I wondered, “how can I make a better, cheaper service for finding photos of myself (and put these guys out of business :P)?” The result is bibfind.com: a crowd-sourced photo tagging system that uses the bib numbers worn by runners to identify them in photos.
