I like using a race belt because I don't have to muck with safety pins, or put holes in things. I picked this idea up from some of the triathletes (along with the speed laces that are still sitting in a package, never put into shoes yet).
But I've discovered a disadvantage -- the big marathon photographer companies (or their software) don't recognize my bib number -- if I put my bib number in, I get photos of random people who are not me.
