Wahoo Kickr Run

If you regularly train for races and want to mimic running outdoors: The Wahoo Kickr Run is a unique treadmill that adjusts to your stride. At $7,000, it’s an investment that some runners will find worthwhile. But for others, this treadmill’s lack of a monitor featuring MPH rates—and its tendency to suddenly stop when ending a workout—may be off-putting. In the Kickr Run’s Run Free mode, sensors automatically adjust the machine’s speed, allowing you to adjust your running pace as you would while running outdoors (as opposed to staying at, say, a 10:00 pace throughout a treadmill run, unless you were to manually change speeds). The layout is simplified: There’s one lever to adjust speeds and one for incline/decline, so you can focus on running. And Bluetooth and Wi-Fi connectivity allow you to stream interactive workouts to a separate device of your own—TV, phone, laptop, or tablet—and connect to Zwift (if you want to broadcast your workout stats from the machine). The Kickr Run’s belt and deck are top-tier and ideal for sprints or interval work—several of our testers said they could envision themselves running for longer on this machine than on most treadmills. The Kickr Run has a warranty of five years for frame, motor, and running belt, one year on all other treadmill parts, and one year on labor by Wahoo authorized repair providers. The Wahoo Kickr Run shows only incline percentage and your pace, though more-detailed metrics are accessible through Wahoo’s app. Marki Williams/NYT Wirecutter
