based on tree size and how many trees, and tree spacing, that hes passing in 10 seconds, average distance between trees is 15 feet, he passes about 39 trees in ten seconds, 39*10=390 390*6 for one minute,equals 2340. 2340*60=140,400, which means 140,400 feet in one hour, which is only about 26.5 MPH, which is 1 mph slower then the fastest human alive.
