Running to and/or from work sounds like a great idea. Too bad my work isn't in the greatest area for running.

As far as packs, I use a Camelbak Alterra lumbar pack for longer training runs. It has a few pockets that I use for gels, keys, cell phone, etc., so if I were going to run to/from work, I'd probably use that. I don't get along as well running with the Camelback that hangs from the shoulders.--

Let us know how it goes.
