COROS Features for Ragnar
Resume Later — Log your entire Ragnar as one activity instead of separate ones. When you finish your first loop, select "Resume Later." Your watch will go back into daily mode, and when you're ready to head out again, you can pick up where you left off.
Navigation — Load the course route directly to your watch via the COROS app before you leave camp. Your watch will alert you if you go off course. COROS APEX 4 and PACE Pro support turn-by-turn alerts. COROS PACE 4 supports breadcrumb navigation.
Pacing Strategy — Set a target pace based on the terrain and your watch will keep you honest in real time. On a relay, your teammates are timing their warmup around when you get back. Staying on pace keeps everyone's day running smoothly.
Flashlight — A little extra light when you need it, built into the watch screen. Useful for finding things in your tent without waking the rest of your team.
Hill Alerts — Your watch will notify you when a significant climb is approaching so you can adjust your effort before you're already in it. Helpful in daylight. More helpful at 2 a.m.
3D Flyover Videos — Once your activity is saved, COROS generates a 3D flyover video of your route. A good keepsake from a long weekend on the trails.
Adventure Journaling — Add voice notes during your activity or written notes after the fact. The Adventure Journal combines your activity data with the sights, sounds, and details you want to remember, so you can relive Ragnar anytime.
