Therun sells through Amazon only, and its own site is a marketing page that links back to the listing, so there is no direct support channel. Its 2 in 1 pad doubles as a light running treadmill, 3.8 mph with the handle folded down and 6.2 mph with it raised, on a 38 by 15 inch belt rated to 300 lb. It arrives assembled and folds under four and a half inches, but there is no incline and the 2.5 HP number is a peak rating.
The THERUN 2-in-1 treadmill features a 2.5HP quiet motor supporting up to 300 lbs, offering speeds of 0.6-3.8 mph as a walking pad and 0.6-6.2 mph as a running treadmill with a raised handle, and includes a 38"x15" 5-layer anti-slip, shock-absorbing belt, an LED display with remote/touch control, all in an installation-free, space-saving design less than 4.5 inches thick when folded.
