Amazon Prime Day is in full swing – and the outdoor gear discounts are huge. We’re talking everything from lightweight tents and waterproof boots to top-tier GPS watches.
Garmin has slashed prices across its entire wearable range, but the standout offer by far is the Forerunner 255. Right now, you can grab it for just £199 – down from £349. That’s 43% off one of Garmin’s most beloved GPS watches.

The Garmin Forerunner 255 is a mid-range multisport watch with a 46mm case, offering onboard music storage, multi-band GPS for superior accuracy, and advanced training features like HRV status and race widgets. It delivers up to 14 days of battery life in smartwatch mode and supports full triathlon tracking, making it a serious upgrade from the Forerunner 245.
If you’ve ever considered picking up a dedicated running watch, this might just be the nudge you need. The Forerunner 255 isn’t the flashiest model in the Garmin lineup, but that’s kind of the point. It’s a tough, lightweight, no-nonsense watch with enough features to satisfy serious runners, triathletes and outdoor adventurers, without the battery-draining extras you might not want or need.
It’s accurate, dependable and widely regarded as one of the best value-for-money multisport watches Garmin has ever made.

You get dual-band GPS, a barometric altimeter, and Garmin’s full suite of training tools including VO2 max estimates, race predictors and suggested workouts.
Daily readiness tracking comes via heart rate variability (HRV) status and the Morning Report widget, which pulls in sleep data, recovery time and more. The battery life is excellent too – up to 14 days in smartwatch mode and 30 hours in GPS mode.
There’s also a Music edition, which adds offline Spotify support and Garmin Pay. But even the base model is packed with enough functionality to make it a great all-rounder for trail running, cycling, hiking and general fitness tracking.

It’s the kind of watch you can put on and forget about, knowing it’ll quietly and reliably keep track of your runs, monitor your recovery, and only bother you when it’s got something useful to say.
In short: if you’re looking for a rugged GPS watch that can handle long runs, big hikes and everyday life without constantly needing a charge, this is a deal well worth your attention. We’ve seen it dip once or twice before, but never by this much. Just don’t hang around – Prime Day deals don’t tend to stick around for long.
