Flickr: Jogging Photography - the official group
Your not the only one with the idea.
I'm not much for jogging really, but I always have my camera on hand and tend to use it quite a bit just in the 30 minute walk from my house to work in the mornings. Of course I'm a photographer so I would be doing that anyways. Does it still count as exercise if my pata-mobile is technically my only mode of transportation?
Edit: uh-oh, the group looks inactive

sorry, my bad
