COROS just started pushing its October 2026 feature update, and the headline is a feature trickling down rather than one arriving at the top.
Full global maps are coming to the PACE 4. Until now the watch handed you a simple route line, what COROS calls breadcrumb navigation, and left you to guess what sat around it. The update gives the PACE 4 the same mapping the APEX 4, NOMAD and PACE Pro already carry: street and trail names, points of interest and offline map coverage.
That's a bigger deal than it sounds for anyone who rides or runs off the beaten path. Seeing where you actually are beats following a line that only tells you whether you're on it.
Maps Reach Almost the Whole Lineup
The mapping upgrade isn't limited to the PACE 4. According to the rollout details, it lands on the PACE 4 Pro, PACE 4, APEX 4, NOMAD, PACE Pro, APEX 2 and 2 Pro, and the VERTIX 2 and 2S, plus the DURA bike computer.
The notable holdout is the PACE 3, which does not get maps. That's a clean line between generations, and it's worth knowing before you buy a discounted older model expecting the feature to arrive later.
A Cycling VO2 Max, Finally
The other headline addition is a cycling-specific VO2 Max. COROS now calculates it from your ride data and shows it both on the watch and in the app, inside the card that already tracks your FTP.
This matters because FTP and VO2 Max describe different things. FTP tells you the power you can hold, while VO2 Max speaks to the size of your aerobic engine. Tracking both over a season gives a fuller picture of whether you're actually getting fitter, and cyclists have long asked for the second number.
It reaches most of the current lineup: PACE 4 Pro, PACE 4, APEX 4, NOMAD, PACE Pro, PACE 3, APEX 2 and 2 Pro, VERTIX 2 and 2S, and the DURA. Older watches like the PACE 2, APEX Pro and VERTIX 1 are left out.
Emoji Notifications and Better Menus
Two smaller changes will be felt every day by far more people than the mapping update.
- Emoji support in notifications. The most-used emojis now render on the watch instead of vanishing or turning into empty boxes. COROS says expanded emoji support is coming.
- Reorganized pre-run settings. Related options are grouped together and the ones you reach for most sit higher up. Navigation moves to the front for Trail Run, and activity alerts get priority in regular Run mode. Less scrolling before you start.
If you own a COROS watch, these are the two updates you'll notice within an hour of installing.
The Rest of the Changelog
Beyond the marquee features, the October update cleans up a long list of loose ends:
- Passcode lock arrives for the PACE 3, APEX 2 and 2 Pro, and VERTIX 2 and 2S
- Automatic max heart rate review, which prompts you to accept a higher value if your recorded data suggests your configured number is too low
- Hill alert and effort pace algorithm adjustments
- DURA storm alerts and a new torque-per-revolution metric for cycling
- A refreshed battery status page in the COROS app
The max heart rate prompt is the quiet one worth paying attention to. Zones, effort estimates and training load all lean on that number, and a value set once during setup and never revisited drags every derived metric down with it.
How to Get It
The update is rolling out through the iOS and Android app stores. COROS says global availability typically follows within about a week of release, so some owners will see it before others.
The order matters. Install the app update first, then check for the watch firmware update. The features that display on the watch, like maps and cycling VO2 Max, need the new firmware on the device itself, not just the phone app. If you don't see it yet, check the store again over the next few days.
Bottom Line
This is a software update that quietly makes a mid-range COROS watch more capable than it was last week. Putting full offline maps on the PACE 4 closes the biggest gap between it and the pricier APEX and PACE Pro models, while the cycling VO2 Max fills a metric cyclists have been asking for.
If you already own a PACE 4 or a PACE 3, the split is the thing to note: the PACE 4 is getting maps, and the PACE 3 isn't. For everyone else in the lineup, this is a straightforward, free improvement, and it follows a steady year of updates for the brand, including the May 2026 feature drop. The COROS PACE 4 remains one of the better value picks in running watches, and the APEX 4 is the step up if you want the tougher build and the full feature set out of the box. The PACE 4 Pro is the top of the Pace line if maps, a brighter screen and longer battery matter more than price.
