The treadmill is approximately 10 years old and works haltingly. We used it only for walking at a slower pace. It might work better at a trot or a run. The Nordic Track is an original and may slip as it is used. Neither has been used for a couple of years. They are free to whoever is willing to carry them up from our basement. Please call 785-639-5049 to take a look at them. You may take either one, or both.
