Navigation and outdoor features: without mapping

This is the weak point. No onboard maps. But you still have:

• Route tracking : follow a route created in the app (breadcrumbs)
• Turn by turn : turn by turn indications during the race
• Breadcrumbs : display of the GPS track in real time
• Return to start : follow your track in the opposite direction to return
• Navigation to POI : go to points of interest
• Barometric altimeter : precise measurement of altitude (manual or auto calibration possible during the activity)
• Compass : basic orientation
• Weather report : forecasts from the app

Multi-band and multi-GNSS GPS (the most precise) or multi-GNSS alone (more durable). Suunto has removed GPS-only mode.

Verdict: sufficient for runners. Not for hikers who need detailed maps.

GPS and sensor accuracy testing

We compared the Suunto Run with a Garmin Forerunner 165 and a COROS PACE 3 on the same routes.

GPS: The dual frequency (L1 + L5) of the Suunto Run offers better precision in urban and undercover environments. The measured distances correspond to our references (Strava, Garmin). No noticeable drift. Rapid signal acquisition (a few seconds).

Optical heart rate: Good performance under normal conditions. Less reliable at high intensity (sprints, intervals). We recommend an external sensor for very demanding sessions. Suunto has improved the sensor compared to previous generations.

Barometric altimeter: Accurate. Manual calibration during activity (new) is useful for mountain runners.

Accelerometer: Automatic detection of laps on track. Works well.

Quick comparison:

Battery life: 20 hours in precise GPS

Suunto announces 12 days in connected watch, 20 hours in dual-band GPS (performance mode), 40 hours in economy mode.

Our actual tests:

• Connected mode (active Bluetooth, continuous cardio): approximately 7-8 days
• Dual band GPS (performance mode): 18-20 hours depending on alerts and screen
• Dual band GPS with always-on display: ~16 hours (20% loss)
• Economy mode (single band GPS): 30-40 hours

Charging: magnetic cable supplied. Approximately 1 hour 45 minutes for a full charge.

Verdict: 20 hours is enough for a marathon (4-5 hours) with battery to spare. Better than the Forerunner 165 (17 hours) and the PACE 3 (15 hours in performance mode). Less than the PACE 3 in economy mode (38 hours).

MP3 player: 4 GB of music without a phone

Rare at this price. You can store your MP3 files directly in the watch.

Limitations:

• MP3 files only (no FLAC, AAC, etc.)
• No support for Spotify, Deezer, Apple Music (streaming)
• 4 GB = approximately 1000 songs in standard quality
• Compatible with standard Bluetooth headsets
• Playback controls from the watch (play, pause, next)

Real usefulness: you can run without a phone and listen to your music. This is a real plus for runners who like to isolate themselves.

Comparison: the Garmin Forerunner 165 Music also offers music, but it costs €299 (Music version). The COROS PACE 3 does not have an MP3 player.

Suunto app and sync

The Suunto app is well thought out. Clear interface. No hassle finding your data.

Main features:

• Creating routes : the creation tool is renowned as the best on the market (according to testers)
• Suunto Route Planner : web version to create from a computer
• AI Analytics : intelligent summaries of your sessions
• Tracking widgets : training load, recovery, progression
• Komoot sync : import routes from Komoot
• Social sharing : share your performances

Synchronization: generally fast (a few seconds after the activity ends). Sometimes slow (rarely, but it happens).

Integration: Strava, TrainingPeaks, etc. No Garmin Connect, but you can export to TCX/FIT.

Advantages and disadvantages: the honest assessment

Direct comparison with competitors

Suunto Run vs Garmin Forerunner 165

Frequently asked questions

Is Suunto Run waterproof for swimming?

Yes. 50 meters (5 ATM). You can swim in pools and open water. No diving.

How long does the battery last in GPS mode?

20 hours in performance mode (dual band). 40 hours in economy mode (single band). Our tests: 18-20 real hours in performance mode.

Can you listen to Spotify on Suunto Run?

No, the built-in optical sensor works fine. But for very intense sessions (sprints, intervals), an external sensor (Bluetooth) improves precision.

Is the Suunto Run suitable for trail running?

Yes, she has a trail profile and the necessary tools. But without mapping, it is less suitable than the Race S for technical trails.

Who is the best competitor?

It depends on your priorities. Garmin Forerunner 165 for the interface. COROS PACE 3 for extreme autonomy. Suunto Run for overall balance (GPS, MP3, AMOLED, price).

Is there a version for small wrists?

No. The 46mm case is unique. But it's compact and lightweight, so it fits even small wrists.

Can the watch be charged without the supplied cable?

No. Suunto uses a proprietary magnetic connector. You have to keep the cable.
