Which should you buy?

Buy the Coros Apex 2 Pro if battery margin and price are your primary concerns for ultramarathon racing. Its 75-hour GPS runtime means a single charge for most 100-milers, and the clean interface reduces fumbling at 2am aid stations. Buy the Garmin Forerunner 965 if you train with Garmin athletes, rely on third-party Garmin Connect IQ apps, or want the richest mapping and turn-by-turn navigation available at this price tier. Neither is a wrong choice at this level.

Common questions

Does the Coros Apex 2 Pro have navigation for unmarked trail courses?

Yes. It supports GPX route import with topographic map overlay, course deviation alerts, and back-to-start routing. The navigation works reliably on singletrack. It does not have the turn-by-turn voice navigation that Garmin offers, but for most trail and ultra runners a breadcrumb GPX route is sufficient.

Can I use the Garmin Forerunner 965 with Strava or TrainingPeaks?

Yes. The Garmin Forerunner 965 integrates with Strava, TrainingPeaks, Final Surge, and dozens of other third-party platforms via Garmin Connect and the Connect IQ app store. If your coach uses TrainingPeaks or your club uses Strava Segments, the Garmin ecosystem connects more cleanly than Coros.

Which watch is better for daily running training outside of races?

Both are excellent daily training watches. Garmin has a more mature training load and recovery analytics platform (Body Battery, HRV Status, training readiness) that many coaches and athletes prefer. Coros has been closing the gap and is excellent for interval sessions and pace-based training. For coaching platforms, Garmin integrates more broadly.
