Running Area

When choosing a treadmill consider how you will use the treadmill mostly and the space available in your room. An 18-inch belt is suitable for walking. For runners, we recommend  20 inches or wider.

The length of a belt can vary from 50” to 65”.  55 inches will work for most people but, if you’re taller than 6 feet go longer.
