The Trailrunner 2.0 is a great running treadmill. It is built to be sturdy and durable, yet in a rare combination it can also fold. Most folding treadmills aren't very stable, at least compared to commercial grade, heavy-duty non-folding treadmills. The Trailrunner has a 3.5 HP motor and goes up to a 15% incline, which are both great for training for runners. As usual, this ProForm treadmill is equipped with iFit Live compatibility, which always makes working out a lot more fun. Definitely a great treadmill at the sale price of $1,499.
