Suunto Summer 2026 Firmware Update Guide: What’s New
Suunto’s summer 2026 firmware update lands across its current GPS watch range, and while it’s not a headline-grabbing hardware launch, it’s a genuinely useful update if you’re already wearing a Vertical 2 or one of Suunto’s other current-generation multisport watches. Here’s what’s actually new, based on Suunto’s release notes and DC Rainmaker’s coverage.
What’s in the update
- Clearer map labelling — water features and mountain peaks now get their own labels on the built-in maps, plus a new layer selection option so you can toggle what’s shown rather than working with a fixed map style.
- Expanded route storage — the number of routes you can store on-watch jumps from 15 to 200, useful if you’re the kind of athlete who loads a whole race season‘s worth of courses rather than deleting and re-adding one at a time.
- New vertical gain training target — for anyone structuring hill or trail training around elevation rather than just distance or time, this adds a dedicated target type instead of having to track climbing manually.
- Tides forecast — more relevant to open water swimmers and coastal athletes than most triathlon training, but a genuinely useful addition if you swim or race in tidal water.
This builds on Suunto’s Q1 2026 update, which improved off-route detection — the watch is now better at recognising when you’ve strayed off a loaded course and shows an arrow back to the route along with remaining distance, rather than just flagging that you’re off-course.
How to update
Updates roll out automatically through the Suunto app once your watch is paired and has a stable connection — open the app, let it sync, and check your watch’s settings menu for the current firmware version if you want to confirm it’s landed. There’s no manual download required.
Which Suunto watch to buy now
If you’re shopping rather than updating an existing watch, the Suunto Vertical 2 is the current flagship these features land on first — dual-band GPS, a bright AMOLED touchscreen, up to 65 hours of GPS battery life in its best mode, and 115+ sport modes covering everything a triathlete needs plus the hiking and mountain features Suunto built its name on.
Suunto’s next major hardware release, the Core 2, isn’t expected until autumn 2026 at the earliest — we’ve got a full Suunto Core 2 preview covering what’s confirmed so far, including the open question of whether it’ll carry GPS at all.
