From the manual of the TT8, the flat top of the belt is 60 inches long with 3 inch diameter wheels at the ends. This gives an effective belt length of about 127 inches when you do the math.
Anyone want to check my math?
The wheel diameter is actually 2.98in (Calibration, step 4). The manual actually doesn't say 60in either, that's in the specifications.
Also, the manual explains why she was touching the treadmill.
