Polar Street X Review 2026: A Solid Mid-Range Option for Urban Athletes

The Polar Street X delivered impressive battery life and heart rate accuracy in our testing, with up to 10 days of use on a single charge. GPS tracking was also reliable, and the watch's sleep staging feature provided detailed insights into rest and recovery. While it may not surpass more premium options like the Coros Pace or Garmin Forerunner, the Street X offers excellent value for its £186 price tag.
