Garmin is no longer the only name in GPS sports watches. Coros and Suunto now fight hard at the budget and mid range, while Apple and Samsung push the premium end, and the whole category has transformed in five years — from a simple activity band into a titanium-cased coach with a dozen sensors, training and recovery analysis, and enough ruggedness to guide you up a mountain or 40 metres underwater. The right one depends entirely on your budget and how seriously you train. Here are the best picks across three price tiers, drawn from published testing.
The Short Version
- Best budget buy — Coros Pace 3. Feather-light, dual-band GPS and a superb app for well under £250.
- Budget bargain — Decathlon Fit 100. A genuine GPS watch for around £70.
- Long-runner — Garmin Forerunner 55. Two weeks of battery and reliable GPS.
- Mid-range star — Huawei Watch GT Runner 2. Titanium, dual-band GPS and mapping under £400.
- Rugged value — Amazfit T-Rex 3 Pro. Sapphire, titanium bezel and 187 sport modes.
- Sport purist — Suunto Race. Mature AMOLED watch with mapping at a keen price.
- AMOLED all-rounder — Coros Pace Pro. Two-week battery and mapping in Coros's first AMOLED watch.
- Flagship — Garmin Fenix 8. The most complete, most rugged sports watch there is.
- Apple's outdoor watch — Apple Watch Ultra 2. Unbeatable ecosystem, iPhone only.
- Android answer — Samsung Galaxy Watch Ultra. The cheapest outdoor "Ultra".
Best Under £250
At this level the emphasis is lightness, battery life and the core sensors, and Coros is busy stealing Garmin's first-time buyers.
Coros Pace 3

The value champion. At around 30 grams it is so light you forget you are wearing it, yet it packs dual-frequency GPS, an accurate heart-rate sensor, breadcrumb route navigation and five to seven days of battery — enough even for those training more than ten hours a week. It skips AMOLED for a transflective screen, which barely hurts readability in daylight and helps that endurance, and its software is refreshingly simple where Garmin's can overwhelm. It even includes onboard music storage, which Garmin reserves for pricier models. It remains our top recommendation; see our Coros Pace 3 review for the full picture. Check the price on Amazon.
Decathlon Fit 100
For roughly £70 the Fit 100 is almost absurd value: built-in GPS, an AMOLED screen, five-day battery and Decathlon's tidy new Hub app, with 14 sports on the watch and 40 more available. The compromises are honest — a screen poorly suited to darkness, occasionally choppy animations and approximate GPS in town — but for a beginner or occasional athlete on a tight budget, nothing touches it. Check the price on Amazon.
Garmin Forerunner 55

Garmin's cheapest running watch is no longer young, but its GPS stays accurate and its two-week battery is monstrous. At just 37 grams it suits swimmers too, with 50-metre water resistance and Garmin Coach training plans. The dated heart-rate sensor loses precision during interval work, and there is no onboard music, but as a dependable running companion it endures. Check the price on Amazon.
Best Under £500
Step up and you gain tougher materials, more and better sensors, AMOLED screens and mapping — features that cost £700 only two years ago.
Huawei Watch GT Runner 2
A remarkable amount of watch for under £400: dual-band GPS with a floating antenna, running power, lactate threshold, mapping and a smart marathon mode in an ultra-thin, ultra-light Grade 5 titanium case, with over a week of heavy-use battery. Huawei Health is excellent and there is onboard MP3 playback, though the closed system blocks third-party apps and there is no cellular. Our Huawei Watch GT Runner 2 review covers it in depth. Check the price on Amazon.
Amazfit T-Rex 3 Pro
Zepp Health aims at watches costing twice as much. Under £400 buys a sapphire screen, titanium bezel and huge battery, a 480x480 AMOLED panel rated at 3,000 nits, 187 sport modes and a dedicated Hyrox mode. Location tracking is excellent and heart-rate tracking consistent; the misses are the busy menus and no Play Store. A rugged specialist that earns its "Pro" badge — and pairs well with a recovery tracker like the Amazfit Helio Strap. Check the price on Amazon.
Suunto Race
Finland's answer to Garmin is a mature GPS watch: precise across every sport, with a clear, intuitive app, full mapping behind an AMOLED screen and a solid five-day battery. It stays focused on sport rather than smart features, and its large case suits bigger wrists — but at its price it is a very good deal. The compact Suunto Race S is the option for smaller wrists. Check the price on Amazon.
Coros Pace Pro
Every new Coros shakes the market, and the Pace Pro is the biggest tremor yet — the brand's first AMOLED watch, with a frankly mad two-week battery, mapping borrowed from its trail range, dual-frequency GPS even sharper than the Pace 3's and an electrical heart-rate sensor for accurate overnight recovery tracking. It is heavier and less armoured than the Pace 3 (no sapphire or titanium), which is precisely how it stays light; the outdoor-focused Coros Apex 2 Pro sits above it for durability. Check the price on Amazon.
Best Under £1000
The top tier chases performance and endurance together: rugged cases, many ultra-precise sensors, quality OLED screens and big batteries, wrapped in premium materials.
Garmin Fenix 8
It needs no introduction — the most complete, most rugged and dearest Garmin, in 43, 47 and 51mm sizes with aerospace-grade stainless steel or titanium. Water resistant to 100 metres with dive sensors to 40, it adds a first-ever AMOLED screen (capped at 1,000 nits to spare the battery), 32GB storage, NFC, an LED torch and up to 47 hours of GPS activity, 16 days without. Its post-activity GPS smoothing beats rivals in tricky terrain. Around £824, it is the benchmark; the AMOLED Garmin Epix is its close sibling. Check the price on Amazon.
Apple Watch Ultra 2
The second Ultra offers Apple's best in a rugged, titanium, dive-capable body, with a screen up to 3,000 nits and 100-metre water resistance. Its sensors are excellent, though Garmin still analyses sport data more deeply, and battery life is the obvious limit for long-distance days. Critically, it works only with an iPhone — Android users should look to Samsung instead. Check the price on Amazon.
Samsung Galaxy Watch Ultra
Samsung's flagship mirrors the Apple Ultra closely, down to the orange strap: a 12.1mm titanium case, a 1.5-inch 3,000-nit AMOLED and 100-metre water resistance. At around £599 it is the cheapest of the outdoor "Ultra" trio, and its heart-rate sensor, GPS and build are all beyond reproach — though, like the Apple, it lasts only about two days. Our Galaxy Watch guide covers the wider Samsung range. Check the price on Amazon.
How to Choose a Sports Watch
Set your budget first, because it maps neatly onto features. Under £250, prioritise lightness, battery and the essential sensors. Under £500, you gain an AMOLED screen and mapping. Under £1,000, ruggedness rules and the software pushes furthest into training analysis. Beyond that, weigh the platform: Apple ties you to iPhone, Samsung leans Android, while Garmin, Coros and Suunto work with both and go deepest on sport. If you mainly want sleep and recovery data rather than a screen on your wrist, a smart ring is worth considering too.
Frequently Asked Questions
What does a sports watch add over a normal smartwatch?
The same sensors, but far more capable — a plain GPS becomes multi-GNSS or dual-frequency for metre-level accuracy anywhere, joined by training-load, recovery and sport-specific metrics a lifestyle watch simply does not track.
How much should I spend?
Enough to match how you train. Casual runners are superbly served under £250 by a Coros Pace 3; serious multi-sport athletes and adventurers get their money's worth from a £500-plus watch with mapping and premium build.
Do I need dual-frequency GPS?
It helps most in cities, forests and mountains where signals bounce or drop. For open-road running a good multi-GNSS receiver is usually enough, but dual-frequency is the safer bet for trail and off-grid use.
The Bottom Line
The sports-watch market is competitive again, and that is good news. For most people the Coros Pace 3 is the smart buy — light, accurate and affordable. Spend more and the Huawei Watch GT Runner 2 and Coros Pace Pro add mapping and AMOLED without breaking £500, while the Garmin Fenix 8 remains the no-compromise flagship. Apple and Samsung's Ultras are the picks for anyone deep in those ecosystems. Match the watch to your budget and your sport, and any of these will train with you for years.
