Some of the best activity trackers for runners include the Apple Watch, Garmin Forerunner 920XT, Fitbit Surge and Basis Peak, according to Runnersworld.com. The Polar M400 and Microsoft Band are also highly-regarded activity trackers.
The best particular activity tracker for any given runner depends on what the runner is looking for out of such a device. The Apple Watch is great for fans of Apple products and features GPS and a slick, visually-pleasing display. Although bulky, the Garmin Forerunner 920XT is excellent for triathletes who love data because it tracks sport-specific metrics. The Fitbit Surge is great for those who need extra motivation and support, since the device is full of encouragement and is designed to track all-day step activity.
