Personally, I've never looked down on any runner. I know plenty of runners in the "penguin" crowd, and I respect anyone trying to improve their health. This issue with races reaching capacity within 24 hours really only affects a handful of big marathons - Boston, NYC, Chicago, and MCM (maybe others?) and a few other popular local races - Army 10 Miler, Cherry Blossom 10. The other fall marathon I'm probably going to do, Richmond, I don't think has ever sold out. 95% of marathons aren't filling in less than 24 hours. So what's the answer for those races? Boston's gone to the qualification system, which is tough but fair, and NYC has a lottery (plus some qualification spots, from what I've heard - never looked into it). Chicago and MCM still use first come/first served, which has twice now crashed Active.com's registration system. MCM has now sold out in less than 24 hours three years in a row, so I think they're going to have to rethink the process sometime soon.
