They're absolutely wonderful for long-distance running. Every 45-60 minutes (typically before a water stop), grab one out of your pocket/belt, bite the head off, squeeze the gel into your mouth, put the discarded head and packet in your pocket (or toss it on the ground if it's a race and littering is expected), and keep running.
They should be available almost anywhere running stuff is sold.
I'm not a fan of GU, preferring instead for the blox, which are more like a gummy bear type consistency. I'll be running a marathon in a few weeks as well, although I don't think security will be much on the minds for this race taking place in still frozen northern MN.
