Garmin Fenix 9 brings rowing FTP and VO2 max via Concept2 link
Garmin's new flagship watch can now calculate rowing fitness metrics when paired with a power-equipped rowing machine — and most of those features are coming to the Fenix 8 for free.
What you need to know
- Garmin Fenix 9 (launched 25 August 2026) adds rowing FTP, VO2 max, lactate threshold and Training Status when paired with a power-meter-equipped rower
- Classification ranges are drawn from Concept2 reference data; a Concept2 PM5 paired via ANT+ FE-C is the most practical setup, but any ANT+ or Bluetooth power meter stream will work
- Nearly all new software features — including the rowing metrics — are being back-ported free to the Fenix 8, Fenix 8 Pro, Forerunner 970 and others; no Garmin Connect+ subscription required
Garmin gives rowers what they have been asking for — and most Fenix 8 owners get it free
Garmin launched the Fenix 9 and Fenix 9 Pro at its "Play Harder" event on 25 August 2026, and while the headline hardware changes are immediately obvious — a twice-as-bright AMOLED display, 64GB of storage, LTE and satellite connectivity extended to solar models — it is a quieter set of additions that has caught the attention of the indoor rowing community. For the first time on a Garmin watch, the Fenix 9 can calculate rowing FTP, VO2 max and lactate threshold, provided it is paired with a power-meter-equipped rowing machine.

DC Rainmaker (Ray Maker) published his in-depth review of the Fenix 9 series on 18 September 2026, and his confirmed feature list makes clear just how substantial the rowing upgrade is. New additions include dedicated heart rate zones and a rowing-specific max heart rate setting, indoor rowing FTP estimation, indoor rowing VO2 max, lactate threshold for rowing, performance condition, a five-second countdown timer for indoor rowing, and — critically — the ability for indoor rowing sessions to update Training Status (Productive, Unproductive, and so on).
Previously, you could pair a rower to the Indoor Rowing profile on a Fenix watch, but you received none of those added metrics. As DC Rainmaker puts it, all of that now happens when you pair a power meter device.
Concept2 is the obvious choice, but not the only one
The classification ranges for both rowing FTP and VO2 max are drawn from Concept2's own reference data — a detail Garmin itself acknowledges. Garmin's product documentation states: "While FTP is widely used in cycling, it is also a meaningful indicator for rowers. In indoor rowing, where body weight does not significantly limit performance, rowing FTP is typically expressed as absolute power (watts)."
In practical terms, if you have a Concept2 RowErg with the PM5 monitor, you pair it as an ANT+ FE-C rower; this also delivers distance and stroke data alongside power. However, the new metrics only require a power reading and a heart rate signal to function. DC Rainmaker confirmed via a tester named Des that no ANT+ FE-C or FTMS device is strictly required — anything outputting an ANT+ or Bluetooth power meter stream will work. Des paired the watch to a bike and it came through in the Indoor Rowing profile.
There is one notable gap. SmartRow — a third-party power meter with variants for WaterRower and chain-based air-resistance machines — transmits via Bluetooth only, and its compatibility with the new Fenix 9 rowing features has not been confirmed at the time of writing.
In a broader structural change, rowing is now its own activity category on the watch. Previously, Row and Row Indoor sat under Water Sports; that move reflects the Fenix 9's new indoor rowing physiology support, according to DC Rainmaker's review.
A major back-porting commitment from Garmin
In an unusual move for the brand, Garmin has confirmed to DC Rainmaker that nearly all new Fenix 9 software features will be pushed down to existing watches on the same unified platform. The list of watches receiving the updates includes the Fenix 8 series, Fenix 8 Pro, Enduro 3, Tactix 8, Forerunner 970, Forerunner 570, Fenix E, and Venu X1. A portion is also headed to the Venu 4 and Vivoactive 6.
A Garmin forum representative confirmed that no features will make their way to the Fenix 7. The Fenix 8, on the other hand, will receive almost all of the new Fenix 9 features — with one caveat: the mapping engine improvements are specific to the Fenix 9 series hardware and will not transfer. Fenix 6 owners and Instinct 3 owners are also outside the group, as those watches sit on separate platforms.
No exact firmware date has been confirmed. The work is expected to arrive with a near-term quarterly update or later in autumn 2026. Crucially, none of these features require a Garmin Connect+ subscription — all will be available free.
Other new features worth noting
The rowing additions are part of a wider sweep of sport-focused changes — something neither the Fenix 8 nor the Fenix 8 Pro managed at launch, where the emphasis was almost entirely on hardware. DC Rainmaker's confirmed list of new features also includes:
- Garmin Epic — groups multi-day events on-device and in Garmin Connect
- Stamina Zone and Stamina Endurance Time concepts, with new Stamina Trending in Garmin Connect
- New Running and Cycling Stamina graphs and curves
- Rucking improvements: pack-weight calorie breakout, a Rucking target calculator, mid-activity pack weight changes, dedicated Rucking Reports, Rucking Multisport mode, and on-device GoRuck structured workouts
- A new XC Ski Indoor profile (a ski-erg activity) — present on the watch even though Garmin left it off the Fenix 9 spec sheet, according to DC Rainmaker
UK pricing and availability
The Fenix 9 is available in 43mm, 47mm and 51mm with an AMOLED display and titanium case. UK prices start from £859.99, confirmed by GPS Training, an authorised UK retailer. The Fenix 9 Pro lists at $1,099.99 in the US; every solar model in this generation is a Fenix 9 Pro inReach Solar, available in 47mm or 51mm only — there is no 43mm solar option. All models are rated to 10 ATM and dive-rated to 40 metres. Expected delivery dates run to 20 October 2026 depending on model, according to GPS Training's listings as at 26 August 2026.
Why it matters
For UK rowers who already own a Concept2 RowErg and a Fenix 8 or Forerunner 970, this is effectively a free training platform upgrade — proper FTP estimation, VO2 max, lactate threshold and Training Status integration arriving via a firmware update, no new hardware required. It also signals a broader shift: where previous Fenix generations launched as hardware stories, Garmin has used the Fenix 9 to deliver the biggest single expansion of sport-science features the line has seen in years, then committed to pushing almost all of them downstream to existing watches. Fenix 8 owners tempted to upgrade should note the genuine differentiators are the brighter display, 64GB of storage, faster map panning and the titanium Pro case — not the rowing metrics themselves.
