Expert opinion
Race 2 scored 81% on tfk’s standard 10-mile GPS accuracy test, against 92% for the Forerunner 970 and 87% for the original Race, a regression rather than an improvement. Performance was flat and uniform across easy and difficult sections alike, a pattern that points to firmware-level distance filtering rather than a chipset limitation, and matches reports on Suunto’s own community forum of a consistent 1 to 1.5% distance shortfall in the recorded FIT file versus raw GPS data. Heart rate accuracy against a Polar Verity Sense reference showed a consistent bias, including an 18.8bpm underreport on a steady-state run and a period of roughly 80bpm recorded during a ramp test where reference devices agreed on values 30 to 50bpm higher; the redesigned 6-LED sensor performs reasonably during sustained steady effort but underreports through transitions into harder effort. Automatic triathlon transitions record the whole activity as a single blended file with no segment breaks; manual transitions correctly produce five separate swim, T1, bike, T2 and run segments.
What’s new versus the original Race
Hardware
- Display grows from 1.43in to 1.5in, with peak brightness up from 1,000 to 2,000 nits
- New LTPO AMOLED panel, adding dynamic refresh rate, better power efficiency and an always-on display option
- Thinner, 12.5mm versus 13.3mm, and lighter, 76g versus 83g in steel
- Redesigned case: bezel ridges removed, flatter lugs, polymer lug construction combined with metal
- Redesigned optical heart rate sensor, 6 LEDs and 4 photodetectors
- New Ambiq Apollo510 processor, roughly twice the processing speed of the predecessor with more RAM
- Storage increased to 32GB on all models, intended for onboard maps
- Battery life claim rises from 50 to 55 hours on dual-frequency GPS
- USB-C charging, replacing the previous connector
Software
- Multiple sensors of the same type can now be saved, not just one
- Climb Guidance improved with waypoints and added route detail
- New watch face and a dynamic recovery widget
- Map downloads over WiFi, without needing to be on charge
- Passcode lock added
- Custom multisport profiles expanded: built in the app by combining multiple sports, transitions selectively enabled or disabled, and changes to a base sport profile propagate to linked multisport profiles

Battery life
Suunto claims up to 55 hours of continuous dual-frequency GPS recording, up from 50 hours on the original Race, despite the move to a larger, brighter LTPO AMOLED display. The LTPO panel’s dynamic refresh rate is the stated reason efficiency improved rather than declined with the larger screen.

Triathlon and multisport
- Automatic transitions in the predefined Triathlon and Swimrun sport modes. In current firmware these record the entire activity as one continuous file with no segment breaks between disciplines.
- Manual transitions record swim, T1, bike, T2 and run as five separate, correctly structured segments
- Custom multisport profiles built in the app, combining multiple sports with selectively enabled or disabled transitions
- Heart rate broadcast from the watch to external devices such as a bike computer, confirmed working with a Wahoo ELEMNT
- Pool swimming drill sets, logged without drill-type tagging
- Multiple sensors of the same type can be paired simultaneously
Navigation
- Onboard maps, downloadable over WiFi without a charger connection
- Climb Guidance with waypoints and added route detail
Other
- Passcode lock
- Dynamic recovery widget
