fitness groups in 518?

"Find a gym partner as hungry as you are"

Where do you look to find people in your area with similar fitness goals? I need someone to workout or go for runs with and NONE of my friends have any interest. I need to find someone to link up with who will push me just as hard as I would push them or say "wanna go for a run?" And have them be down for it.

Suggestions, tips, direction?
