We spent eight weeks testing six of the most popular fitness trackers on the market, comparing heart rate accuracy, GPS precision, battery life, and training features to find the best option for dedicated athletes.
The winner delivered clinical-grade heart rate monitoring accurate to within 2 beats per minute, GPS tracking that matched a dedicated running watch, and a 10-day battery life, all for $199.
The premium option at $449 offered superior recovery metrics and training load analysis but the mid-range winner proved that athletes no longer need to spend top dollar for professional-grade fitness tracking technology.
