Are you looking for a watch that can take you from the roads onto the trails and beyond then the COROS APEX 2 has you covered. Geared for the trails, the COROS APEX 2 is incredibly lightweight, weighing just 42 grams with a comfortable nylon band. The smaller profile of the APEX 2 compared to the APEX 2 Pro also makes it great for anyone with smaller wrists or looking for a more compact GPS watch for trail running. The optical wrist-based heart rate monitor gives you accurate data during activities and 24/7 tracking of essential metrics like recovery, HRV and sleep tracking. Make exploring easier with the Route Planner in the COROS Training Hub app, or use other systems like Strava or Komoot to build your route and sync it seamlessly to your APEX 2. Enhance your navigation experience by adding checkpoints or aid stations and get deviation alerts so you stay on course. The preloaded landscape maps or downloadable topographical maps will make following your route incredibly simple. Combining this with the elevation profile views and sun movements makes this one of the best trail and ultra marathon running GPS watches.
