anyone?

I need some help. I remember hearing about a site where you can enter in the route you take while walking/jogging/biking, and it will tell you the mileage you covered. Obviously this would apply to neighborhoods and city streets, not trails, etc. Anyway, I can't find it, and since I'm starting to walk/jog with *ja* two night a week (outside too, not in isolation on my treadmill!), I really want to be able to get an accurate measure of what we're doing without buying a pedometer. I thought about using something like hop stop and entering in the route piece by piece, but really, that's just ridiculous. Plus, I don't think it would be accurate at all. Grrr....I remember hearing about the site sometime in july. Now I'm kicking myself that I didn't write it down.
