Forerunner 255 vs Venu 4
How these two compare on everything we measure — where the AIs rank them, what reviewers and buyers say, and how they price. The differences are the point — they decide which one is yours.
Side by side
Every signal we hold, on one shared scale. The leading side is lit — and where the AI panel and the reviewers pull apart, the row says so.?
Built from what 5 AI models (Perplexity · Google-ai-mode · ChatGPT · Claude · Gemini) recommend for real buyer questions, layered with reviewer test summaries, Google buyer ratings, street prices and press. The short answer and verdict are derived from where those signals diverge — not written by hand for either product.

Critics & buyers
The human jury in one chapter — what the video reviewers score and say, the reviews behind it, and how Google buyers rate them.
What reviewers say
Distilled from the video reviewers — the score, what they praise, where they push back.?
Reviewers praise
- Multi-band GPS accuracy stands out, especially in challenging environments with tall buildings
- Full triathlon capabilities with open-water swimming and cycling power meter support now included
- Fourth-generation optical heart rate sensor performs well across activities
Reviewers push back
- Music version limited to four gigabytes of storage versus much more on higher-end models
- Optical heart rate sensor accuracy varies by user—skin tone, tattoos, and wrist anatomy affect readings
- Lacks Climb Pro feature found on more expensive models
Reviewers agree the Forerunner 255 delivers exceptional value by bringing premium features—multi-band GPS, triathlon support, barometric altimeter, and HRV tracking—down to a mid-tier price, making it a standout upgrade from the 245.
Reviewers praise
- Comfort and wearability: multiple reviewers independently note the watch is lightweight and thin enough to forget it is on the wrist, with a smooth band that causes no irritation.
- Significantly expanded sport and training features — including training load, hill score, pace pro, heat and altitude acclimation — that were previously absent from the Venue line.
- Bright AMOLED display that reviewers report is easily readable outdoors even in strong sunlight.
Reviewers push back
- No full colour turn-by-turn maps on the watch face; only breadcrumb navigation is available, which is a notable gap versus sport-focused alternatives in the same class.
- Touchscreen-only navigation creates frustration during sweaty workouts or when wearing gloves, unlike button-driven alternatives in Garmin's lineup.
- Removal of the dedicated shortcut button present on the previous generation was criticised as a step backwards in usability.
“It feels like you can wear this and actually train for a real race and it's a legitimate watch for doing that.”
One reviewer questions value of the music version due to low storage; others accept the limitation or carry phones
Battery life under real-world conditions drew different readings: one reviewer tested four to five days with always-on display enabled during active summer training, while rated figures suggest up to ten to twelve days in smartwatch mode — reviewers caution the gap between rated and lived experience varies considerably by use pattern.
