A GPS running watch is the most important piece of kit a serious runner can buy. It tracks your training, guides your pace, and tells you when your body needs a rest. But the market is crowded with options at every price point. Here are the five best in 2026.
Garmin Forerunner 965
From £450 · Available at Amazon UK
The Forerunner 965 sits in the sweet spot of Garmin's lineup — all the training metrics a serious runner needs without the bulk and weight of the Fenix. AMOLED display, up to 31 days battery, and training load tracking that actually works.
The training readiness and HRV status features have become genuinely useful over time — this watch learns your patterns and gives advice that actually reflects how your body is responding.
Pros
- AMOLED display is stunning
- 31 day battery life
- Best-in-class training analytics
- Lightweight at 53g
Cons
- Expensive
- Some features need Garmin Connect subscription
- Not as rugged as Fenix
Suunto Race S
From £380 · Available at Amazon UK
Suunto have always understood trail runners better than anyone, and the Race S is their best watch yet. The topographic maps are genuinely useful in the mountains, the battery lasts up to 26 hours in GPS mode, and it's built to handle whatever the outdoors throws at it.
The interface takes some learning but the route navigation is class-leading for trail and mountain running. If you spend serious time in the hills, this is the watch.
Pros
- Best trail navigation in the category
- Topographic maps built-in
- Rugged construction
- Excellent battery life
Cons
- Steeper learning curve than Garmin
- Smaller ecosystem than Garmin
- AMOLED display drains battery faster
Coros Pace 3
From £175 · Available at Amazon UK
The Coros Pace 3 is the best value GPS watch on the market and it isn't close. At £175 you get dual-frequency GPS, a 17-day battery in daily use, and training metrics that rival watches costing three times more.
Coros have built their reputation on making serious performance tools accessible. The Pace 3 is light, fast, and remarkably accurate. The only compromise is the smaller ecosystem compared to Garmin.
Pros
- Outstanding value for money
- Excellent battery life
- Dual-frequency GPS accuracy
- Lightweight and comfortable
Cons
- Smaller app ecosystem than Garmin
- Less intuitive interface
- Fewer third-party integrations
Garmin Fenix 8
From £700 · Available at Amazon UK
If you want the most capable GPS watch money can buy, the Fenix 8 is the answer. Solar charging, built-in torch, dive mode, ski mode, ballistics calculator — it does everything. For serious multi-sport athletes it's genuinely in a class of its own.
It's heavy, it's expensive, and most runners won't use half the features. But if you do multi-sport and need one watch to rule them all, nothing comes close.
Pros
- Most comprehensive feature set
- Solar charging extends battery
- Incredibly rugged build
- Multi-sport king
Cons
- Very expensive
- Heavy at 89g
- Overkill for pure runners
- Chunky on smaller wrists
Garmin Forerunner 165
From £220 · Available at Amazon UK
The entry point to serious Garmin running watches. The Forerunner 165 delivers the training metrics that matter — pace, heart rate, VO2 max estimation, and training load — without the premium price of the 965.
The AMOLED display is a genuine upgrade over older budget Garmin models and the battery life is solid at 11 days daily use. For recreational runners or those new to GPS watches, this is the one.
Pros
- AMOLED display at this price
- Solid battery life
- Core training metrics well executed
- Garmin ecosystem access
Cons
- Missing advanced training features
- Shorter battery than Coros Pace 3
- No music storage
