Suunto sells the 5 Peak as a watch built for "training, exploration and wellbeing". The word exploration implies two basic instruments on any outdoor watch: a barometric altimeter and an electronic compass. The 5 Peak has neither, and the product pages are in no hurry to tell you.

The Suunto 5 Peak bets on low weight (39 g) and flexible battery life of up to 100 hours for 299 euros. It claims an outdoor positioning without the two instruments that define a real trail watch: no barometer, no electronic compass. That's a defensible choice for a road runner or an occasional hiker, and a much harder sell next to the Suunto Run, released later with an AMOLED screen and dual-band GPS the 5 Peak lacks, for less money.
Suunto puts the 5 Peak in the same family as the Vertical and the Race: the word "Peak" and the focus on multi-GNSS suggest a hiking or light trail watch. In reality, the 5 Peak has no barometer and no electronic compass, two sensors you'll find on much cheaper watches from Garmin (the Instinct 2, also under 300 euros, has both). Within Suunto's own lineup, the Vertical offers them at 599 euros. So the 5 Peak sits in an odd niche: a light multisport watch that borrows trail vocabulary without the full trail toolkit.
The 43 mm polyamide case with a stainless steel bezel and the claimed 39 grams (41% lighter than the model it replaces in the Suunto 5 range, according to one French review) confirm the product's real priority: low weight on the wrist over outdoor toughness. A defensible choice, as long as you know exactly what you're buying.

For runs on the road, on marked forest trails or on the track, the missing barometer and compass almost never hurt: GPS is enough to track distance and pace, and French reviews agree on tracking accuracy within roughly 1% over a given distance. This is the product's most natural audience.
On short outings over rolling terrain, the 5 Peak still does the job, but take the displayed altitude (calculated by GPS alone, with no barometric sensor) with a grain of salt: the three French reviews read for this article independently call it "underestimated" or "highly variable". For serious climbing or off-trail navigation, a watch with a barometer and compass is still the better pick.
With 80 sport profiles, swim tracking one French tester rates as reliable and battery life that can reach 100 hours in Tour mode, the 5 Peak covers a lot of ground for someone who mixes running, cycling, swimming and hiking without chasing race results.

RunMorph tip: before picking the 5 Peak for hilly trail running, compare it with the Garmin Instinct 2, which packs a barometer and a compass for a similar price.
Three French reviews took the 5 Peak into the field, over periods ranging from a few runs to a full month. On distance, the consensus is clear: Sport-Passion measured tracking "fairly faithful to the route taken", with deviations under 1% against other watches worn at the same time, and RunMag recorded a maximum error of about 300 meters on a 30 km trail run, again close to 1%. The optical heart rate sensor gets a more mixed verdict: RunMag calls it "a fairly good student" while flagging "unexplained spikes or dips" during effort, and Journal du Trail reports erratic behavior during intervals, a common flaw of entry-level optical sensors.
The three sources do split on altitude, though: with no barometer, the reading relies on GPS alone, and Sport-Passion finds it "rather underestimated" while Journal du Trail calls it "highly variable" on bumpy terrain. This isn't an isolated glitch, it's the direct and predictable result of having no barometric sensor. Swimming is a different story: one tester ranks it among the most reliable models he has tested across all brands, a strong point the product pages rarely mention.
Two structural limits come up in all three reviews read for this article. First, altitude, as covered above: without a barometer, the elevation gain shown on a hilly route can stray far from reality, which makes the 5 Peak unreliable for planning an effort around a precise climbing target. Second, navigation: without an electronic compass, when the GPS signal drops or you stop, the digital route pointer (the breadcrumb trail Sport-Passion nicknames "Tom Thumb") simply vanishes from the screen. You then have to reopen the app or rely on a visual landmark, a hassle a watch with a compass spares you.
On mapping, the 5 Peak never shows a base map: just a route built in the Suunto app and sent to the watch, with an off-route alert. Testers praise how easy route creation is from a smartphone, but the guidance is a bare line on a black background, far from the topographic maps offered by the Suunto Vertical or Suunto Race 2 at a higher price.
The three modes Suunto claims are confirmed by the reviews: 20 hours in Performance GPS (maximum accuracy), 40 hours in Endurance mode and up to 100 hours in Tour mode, with track quality degrading as the GPS sampling interval stretches (RunMag notes a "fairly degraded track" in Endurance mode). In smartwatch use, battery life drops to 7 days, well short of the Suunto Run and its 12 days. A full charge takes between 1 hour 30 and 1 hour 40 via USB cable. One tester flags an oddity worth watching: a "10 hours remaining" readout while the battery still showed 69% charge, which raises questions about how linear the software's battery estimate really is.

| Criterion | Suunto 5 Peak | Suunto Run |
| Price | 299 euros | 249 euros |

The short version: the Suunto Run, released after the 5 Peak, costs 50 euros less and beats it almost everywhere, except for the 100-hour Tour mode that only the 5 Peak offers. At RunMorph, unless you specifically need extreme battery life in a degraded mode, the Suunto Run is the more sensible pick in Suunto's current lineup for the same budget.
| Criterion | Suunto 5 Peak | Coros Pace 2 | Garmin Forerunner 55 |
| Launch price | 299 euros | 199 euros | 159 euros |
| Weight | 39 g | 29 g | 37 g |
| Barometer | No | No | No |

| Mapping | No | No | No |
None of the three watches has a barometer: on that specific point, the 5 Peak gives nothing away to its closest rivals, it's just more expensive. So the decision comes down to budget: the Coros Pace 2 gives you 10 more hours of GPS battery for 100 euros less, and the Forerunner 55 remains the cheapest way into a Garmin ecosystem that's richer in third-party apps. The 5 Peak only makes sense against them if the Suunto ecosystem (route creation, swim tracking rated as reliable) matters more to you than price.

The 5 Peak fits a road runner or multisport athlete who wants a light, long-lasting watch without paying for maps or multi-band GPS they'll never use. Paired with a RunMorph training plan, it handles easy aerobic runs, long runs and even intervals without trouble, with the caveat already mentioned about how stable the optical heart rate sensor is at high intensity.
The Suunto 5 Peak is a good lightweight watch for running on roads or marked forest trails, not a real trail watch despite its name. 6.7/10. The score doesn't reward the price: at 299 euros, with no barometer, no compass and no maps, it costs more than the Coros Pace 2 and the Suunto Run, two rivals that match or beat it on at least one major technical spec. What saves it is genuinely low weight on the wrist and battery life that can climb very high in degraded mode, two strengths independently confirmed by the three French reviews read for this article.
