FAIL.
The wheel diameter is actually 2.98in (Calibration, step 4). The manual actually doesn't say 60in either, that's in the specifications.
Thanks for checking my math, so the belt length would be about:
2*60 + 3 * Pi = 129.36 inches
Given that the other poster says the belt length new is 128 inches with up to 129 inches when stretched, I will use the greater 129.36 inches since that will give Amy Hughes a little bit more distance for the vendor of the doubt.
Using this revised number, Amy Hughes running speed in the video would be about 4.6 mph and a walking speed of about 2.94 mph.
