Coros
Coros builds GPS watches for athletes who care more about their training than about notifications. Their focus is simple: accurate data, battery life that lasts for weeks instead of days, and watches light enough that you forget you're wearing one.
The lineup covers every kind of runner. The Pace series is light and fast for road and track, the Apex suits trail and mountain runners, and the Vertix is built for ultra distances and big days in the Alps. Every watch connects to the free Coros app and Training Hub, where you can plan workouts, track your training load and see how your fitness develops over time, with no subscription needed.
