Projecting 3ish map miles per hour. I say map miles because of the upping and downing- driving my primary route, the map says 96 miles, but my odometer thinks more like 110. I'm not going to push it- if you push it, you are more likely to hurt yourself. If I'm on foot, odds are 3mph vs 5 mph isn't going to mean diddly squat.

Unless they are 4 mph zombies. In which case... ah, man....
