Which Garmin Fitness Tracker Should You Buy? A Practical Guide to Their Best Models

Garmin's 2024 lineup delivers genuine choice depending on what you actually need: a lightweight daily fitness tracker, a full-featured GPS smartwatch, or something in between. The Forerunner 165 Music at £305.99 is the standout for most people — it tracks running with GPS precision, stores 500 songs, and costs £44 less than Garmin's premium alternatives. If you want something lighter and cheaper, the Vívosmart 5 (£149.99) is lean and focused. The Venu X1 (£349.99) is for those who need every feature Garmin makes.

Why Garmin?

Garmin was founded in 1989 and built its reputation on GPS technology — they didn't rebrand as a "lifestyle" brand, they specialised in sports-specific tracking from day one. That focus matters: their algorithms for running metrics (cadence, stride length, V02 max estimation) are genuinely more sophisticated than generic smartwatch makers. They also own their own satellites and processing software, not licensed from third parties. What sets them apart now is music storage (rare in fitness watches under £400), customisable sport profiles (18+ pre-loaded activities), and battery life that actually matches their claims — the Forerunner 165 lasts 11 days in smartwatch mode, not the 2-3 days you get from Apple or Garmin's older models.

Top Picks

Garmin Vívosmart 5 — £149.99

Best for commuters and casual fitness trackers who don't run or cycle seriously. This is Garmin's no-nonsense option: it's a slim band (not a watch face), tracks steps/calories/sleep, monitors heart rate continuously, and syncs everything to your phone. No GPS, no music, no fancy features — just a 7-day battery and a device that disappears on your wrist. It's the cheapest entry point to Garmin's ecosystem and genuinely useful if you want daily activity data without the weight or cost of a smartwatch.

Garmin Forerunner 165 Music — £305.99

Best for runners and gym-goers who want GPS tracking, music, and a watch you can actually use. This is the practical sweet spot: 11-day battery life, built-in GPS for accurate route tracking, 500-song storage so you don't need your phone for workouts, and 18+ sport modes including running, cycling, swimming, and strength training. The screen is 1.04 inches (small but readable), and it syncs to Strava, TrainingPeaks, and other platforms. It lacks some premium features (no blood oxygen tracking, no offline maps), but for £305.99 it's hard to beat.

Garmin Venu X1 — £349.99

Best for athletes who want everything: blood oxygen tracking, offline maps, training load metrics, and Garmin's most advanced recovery suggestions. The 1.4-inch AMOLED screen is sharper than the Forerunner 165, battery lasts 11 days, and it includes all 18+ sports modes plus advanced running dynamics. The downside is it's £44 more expensive and heavier than the Forerunner 165, without major practical differences for most people — unless offline maps or blood oxygen data are essential to your training.

Quick Comparison

| Model | Price | Best For | Standout Feature | |-------|-------|----------|------------------| | Vívosmart 5 | £149.99 | Daily activity tracking | 7-day battery, slim band design | | Forerunner 165 Music | £305.99 | Runners and gym-goers | 500-song storage, 11-day battery, GPS | | Venu X1 | £349.99 | Advanced athletes | AMOLED screen, blood oxygen tracking, offline maps |

What to Look For

• GPS accuracy: All three models include GPS or high-sensitivity location tracking, but the Forerunner 165 and Venu X1 calculate pace/distance to within 2-3% accuracy for runs over 5km — critical if you're training for a race.

• Battery life vs. daily charging: The Vívosmart 5 lasts 7 days, while the Forerunner 165 and Venu X1 last 11 days in smartwatch mode. If you switch to GPS-only mode, expect 10-14 hours of continuous tracking — enough for ultramarathons but not multi-day events.

• Music storage: Only the Forerunner 165 and Venu X1 store 500 songs; the Vívosmart 5 has none. If you run without your phone, music storage is worth the extra £156-£200.

• Sport-specific features: All three track running, cycling, and swimming, but the Forerunner 165 and Venu X1 calculate advanced metrics like VO2 max, training load, and recovery time — useful for structured training, less so for casual exercise.

The Bottom Line

Buy the Garmin Forerunner 165 Music (£305.99) if you run, cycle, or gym regularly and want music storage without premium features you won't use. If you're sedentary or just want daily step counting, the Vívosmart 5 (£149.99) saves you £156 and does that job better. Only choose the Venu X1 (£349.99) if blood oxygen tracking or offline maps are genuinely part of your training or travel plans.

Frequently Asked Questions

Is Garmin worth buying over Apple Watch or Fitbit?

If you run or cycle, yes. Garmin's GPS algorithms and sport-specific metrics (cadence, stride, VO2 max estimation) are more advanced than Apple Watch, and their battery lasts 2-3x longer. Apple Watch wins on ecosystem integration if you're deep in iOS; Fitbit wins on price if you only want basic step counting. Garmin is the specialist choice for athletes.

How accurate is Garmin's GPS for running?

Very accurate. The Forerunner 165 and Venu X1 calculate pace and distance to within 2-3% error over 5km+ distances, which is competitive with dedicated running watches costing £500+. The Vívosmart 5 has no GPS, so it estimates distance from step count (less reliable for running).

Can I use Garmin watches without a smartphone?

Partially. All three models sync to Garmin's app via Bluetooth, but the Venu X1 can download offline maps and work independently. The Forerunner 165 needs your phone to access some features like live tracking and music streaming (music stored on the watch plays without a phone). The Vívosmart 5 requires a phone to sync data.

Which Garmin watch has the longest battery life?

The Forerunner 165 Music and Venu X1 both last 11 days in smartwatch mode. The Vívosmart 5 lasts 7 days. In GPS-only mode (continuous tracking), all three last 10-14 hours depending on settings — enough for a full-day event but not multi-day endurance sports.
