All treadmills aren't created equal. Whether you're purchasing a treadmill for home use or selecting one to use at the gym, if you're a runner there are certain components and features that will help you make the most of your training sessions. Take a good look at a treadmill's structure and features before using it for running--particularly if you're making an investment in your home gym.
Motor and Belt
Manual treadmills are only suitable for walking, so you'll definitely want a motorized version. Running on a treadmill places more strain on the motor since it has to move the belt at higher speeds to keep up with your pace. Choose a treadmill that has a motor with a continuous duty rating of at least 2.0 horsepower. Treadmill motors rated at 2.5 or 3.0 horsepower are even better. Measure the belt to make sure it is wide enough and long enough to accommodate your running stride. A belt that is at least 58 inches long will minimize the risk of tripping or falling off the machine when you run, though an even longer belt will give you more room. An 18- to 20-inch wide belt is the narrowest you should go for running. Make sure the deck underneath the belt is pre-lubricated to reduce friction between the belt and deck. Some treadmills feature a reversible deck, which is a good choice for runners since the deck tends to wear out under the force of running steps.
Speed and Incline
Choose a treadmill with a low starting speed of 0.1 mph to help you get your footing when you turn the machine on. Make sure the speed is easy to adjust and look for a treadmill that goes up to at least 8 mph to help you get the most out of your running workout. For sprinting training, try to purchase a treadmill that goes even faster. Check to see how the treadmill changes elevation. Some machines feature a manual crank, which is more difficult to adjust than a treadmill that allows you to adjust the incline electronically. A treadmill for running should incline at least 10 to 12 percent. Some treadmills also adjust to a 2 to 3 percent decline, which is useful for runners training to run downhill.
Console
Most motorized treadmills feature a computer console that stores and displays various types of data and allows you to adjust the speed and incline. Select the features you want to help you reach your fitness goals. For many runners, this will include a model that displays distance, speed, time and perhaps calories burned. Purchase a model that allows you to store data from previous workouts if you want to compare times to help you increase your speed and endurance.
Other Features
Choose a treadmill that has side handles or bars to help you stabilize yourself if needed and prevent falls but make sure the bars are spaced wide enough that you won't hit your arms while running. Runners should select a treadmill with an emergency shut-off tether that clips to their clothing. These tethers will automatically stop the belt on the treadmill if you begin to lose your footing or slip off the back of the treadmill.
