Suunto's Race 3 family has been building for months, first through a regulatory filing, then through references on Suunto's own site, then through retailer listings. Now there is a date and a price attached to the smaller model, plus a battery claim that would be the real story if it holds up.
Newly surfaced product material points to a target launch of October 15, 2026 for the Suunto Race 3S and a $499 US recommended price. The same material lists a battery change that acts as the headline upgrade.
There is one caveat, and it belongs near the top rather than buried at the end. The outlet that published the material says it could not independently confirm it is genuine, and that AI image-detection tools returned conflicting results. Treat what follows as an unverified leak, not confirmed product information.
What the Material Claims
The Race 3S is described as staying close to the current Race S in size and shape. The listed numbers are 45mm across, 11.4mm thick and 53 grams, which matches the titanium Race S on weight and thickness.
The spec bumps start once you get past the case:
- Display: 1.32-inch AMOLED, 466 x 466, brightness jumping from 600 nits to 2,000 nits
- Glass: Gorilla Glass replaced by sapphire crystal
- Storage: 32GB to 64GB
- Battery: up to 45 hours of dual-band GPS in Performance mode, up from 30 hours on the Race S
- Cell type: described as silicon-carbon anode battery technology
- Colours: Titanium Orchid, Titanium Feather and Titanium Black
The training feature list reads as expected for a Suunto trail watch: dual-band GNSS, free global topographic maps, a Trail Race Planner with climb guidance, Training Zone, Energy Sense, AI Coach support, and SuuntoPlus integrations across more than 120 sport partners. Most of that is refinement rather than anything new to the platform.
The Battery Claim Is the Interesting Part
Doubling GPS endurance in a case that is the same thickness and weight is not something you get for free, and the material's own explanation is the reason this leak is worth a closer look.
Silicon-carbon cells hold more energy per unit of volume than the graphite-based lithium-ion designs used in most sports watches. If Suunto has moved to silicon-carbon, that would explain how it could raise capacity without making the watch thicker or heavier. Other renders in the same set list 45 hours in Performance mode and 55 hours in Endurance mode, with an Ultra mode visible but its runtime obscured.
For context on the rest of the lineup, the Race S in the sportier end of Suunto's range is the model being replaced here, and a chest strap like Suunto's Smart Heart Rate Belt remains the better option for anything interval-based, whatever the wrist sensor claims.
Where This Leaves the Track Record
We have followed this launch through every step. The original Race 3 and Race 3 S leak in July came straight off Suunto's own website and included the AI Coach subscription that had the community fired up. The IMDA certification in August gave the models a second, harder paper trail.
An earlier retailer listing adds weight that the leaked material alone does not. A Belgian and French retailer briefly listed the Race 3S at 498.90 euros in Titanium Black, which is roughly the old price of the stainless steel Race 2 in the US and well under the 599 euros and $599 Suunto charges for titanium versions of the Race 2. That listing is a commercial signal rather than a marketing asset, so it is a firmer piece of evidence than a slide deck nobody can authenticate.
The two threads disagree slightly on timing. The retailer pricing leak suggested a launch before the end of the year. The new material points at October 15. Those are compatible, and Suunto has not confirmed either.
What to Watch
Three things would settle this quickly.
The first is an IMDA or FCC update that names the launch window, since Suunto's regulatory trail has been accurate so far. The second is a Suunto store page going live ahead of schedule, which is how the original Race 3 details leaked in the first place. The third is the estimate itself. If silicon-carbon is real and the Race 3S holds a 45-hour dual-band rating at 53 grams, that changes what the middle of the sports watch market can offer on battery, and competitors will have to answer it.
Until then, the honest read is that the spec sheet looks plausible, the timing looks plausible, and the only thing the publisher can vouch for is that the material exists.
Bottom Line
Suunto has spent the year with a Race 3 family stuck just short of launch, confirmed by filings and retailer pages but never by the company. The latest material gives that story a date, a price and a battery technology worth arguing about, while also carrying a verification problem the publisher flagged itself.
If October 15 is real, we will know within two weeks. If it slips, the pattern from this year suggests the watch is still coming, just later than the leak said.

The launch date, price and battery specification all trace to a single publisher's unverified material with no independent confirmation, so they are attributed as an unverified leak rather than confirmed information.
