Best running watches UK (2026)
Pace, distance, heart rate zones and a training plan on your wrist — the tools that turn running into training. Four picks by budget.
The short version
Garmin Forerunner 165 for most people (best training ecosystem, bright screen). Coros Pace 3 if you want double the battery for less money. Forerunner 265 for serious marathon builds. Amazfit Bip 6 to start for under £100. Then use the heart-rate zones — that’s the whole point.
What a running watch actually does for you
Three things a phone strapped to your arm can’t: accurate pace and distance from proper GPS (so your training runs are the right length and speed), heart rate zones (so easy runs are actually easy — the mistake nearly every beginner makes), and structured training plans delivered to your wrist that adapt to how you’re recovering. Battery life and screen type are the real differentiators at each price.
Garmin Forerunner 165

- Bright AMOLED screen
- ~11 days battery
- Garmin Coach training plans
- Accurate GPS & HR
The sweet spot: Garmin’s training ecosystem (the best there is) at the entry price, a screen you can read in sun, and daily suggested workouts that adjust to your recovery.
For a charity-run training block, the built-in race-adaptive plans alone justify it.
£161.30Coros Pace 3

- Up to 24 days battery
- Dual-frequency GPS
- 30g — you forget it’s on
- Excellent training app
Lighter, cheaper and lasts twice as long as the Garmin; the always-on screen is less pretty but perfect outdoors. Coros’ training platform is superb and free.
The value pick, and the one many experienced runners quietly prefer.
£199Garmin Forerunner 265

- Training readiness & load
- Multi-band GPS
- Music storage
- AMOLED
Adds the deeper metrics that matter once you’re training seriously — training readiness, load balance, recovery time — plus the accurate multi-band GPS.
For a marathon build where you want the watch to tell you when to back off.
£301.90Amazfit Bip 6

- GPS & heart rate
- Long battery
- Under £100
- Big readable screen
Everything a beginner needs — GPS pace, distance, heart rate — for the price of a pair of socks and a pint. Not the training depth of the Garmin or Coros, but a real running watch.
If you’re not sure running will stick, start here and upgrade when it does.
£79.99Whatever the watch, the number to obsess over isn’t pace — it’s keeping easy runs in zone 2. That single habit is the difference between a training block that builds you and one that breaks you; the training plans guide explains why.
Frequently asked questions
Do I need a running watch for a charity run?
Not strictly — but a GPS watch with heart rate makes training far more effective: you run the right distances, keep easy runs genuinely easy, and follow a structured plan. For a first 10K a phone app works; for a half or marathon a watch pays for itself.
Garmin Forerunner 165 or Coros Pace 3?
Garmin for the brighter AMOLED screen and the best training ecosystem; Coros for double the battery life, lighter weight and a lower price. Both track accurately — it's a taste and budget call.
How accurate is wrist heart rate?
Good enough for zone training on steady runs; less reliable in intervals and cold weather. If you want precision, pair a chest strap — all the watches here support one.
