Find out more about how we test running watches

Every running watch we test is used by the reviewer for at least a week – or longer, if the battery life lasts beyond that point or we need more time to trial its features. During testing, we evaluate key metrics including app support, usability, battery life, and the accuracy of fitness and distance tracking.

For distance tracking, we assess how accurately the device records runs on tracks we know the length of. We also evaluate the level of battery life lost per hour using features such as built-in or connected GPS. To check heart rate accuracy, we compare the results from the wearable to a dedicated HRM strap.

Next, we combine the data recorded with our general experience of using the wearable day-to-day, revealing whether the device proved comfortable to wear, alongside any issues we may have encountered with unexpected bugs over the review period.
