Garmin’s numbering system for its Forerunners could be unnecessarily sophisticated. So when the Garmin Forerunner 745 ($150 off) is $249, however the Forerunner 255 ($100 off) is additionally $249, it may be just a little complicated which Cyber Monday deal you should purchase.
As a result of these offers are promoting out rapidly earlier than the official Cyber Monday launch, I will not waste your time with any extra preamble: the 2020 Forerunner 745 is technically a higher-end mannequin than the 2022 Forerunner 255, however the brand new software program and tech constructed into the 255 make it the higher buy. If you’d like a comparatively low-cost Garmin operating watch, select the 255.
To be clear, the Forerunner 255 and 745 are each very comparable watches in software program options. They each observe the coaching impact of cardio or anaerobic runs, your present coaching load, your efficiency situation, and your predicted race tempo based mostly in your VO2 Max. You may comply with Garmin Coach exercises or every day instructed exercises, based mostly in your present restoration time.
Additionally, in very particular areas, the Forerunner 745 wins: it has 4GB of built-in music storage and wi-fi downloads, whereas it’s a must to pay $50 extra for the 255 Music model for each perks. And it makes use of a greater Gorilla Glass DX protecting materials, as an alternative of Gorilla Glass 3 on the Forerunner 255.
In any other case, although, the Forerunner 255 handily beats the 745 in key areas. For starters, it lasts 2 weeks per cost, twice so long as the 745. It has dual-frequency GPS or all-systems GNSS for super-accurate monitoring — one thing I famous in my evaluation — whereas the 745 solely makes use of one GNSS at a time.

Plus, the Forerunner 255 lasts 30 hours in GPS-only mode or 16 in dual-band mode, whereas the Forerunner 745 lasts 16 hours max with GPS-only. This similarity solely makes the hole between them much more apparent.
The 255 has wrist-based operating dynamics and energy readings, whereas the 745 wants a Pod accent. Whereas each weigh about the identical, the 255 has a bigger show (1.3-inch vs. 1.2-inch) and a second petite 255S choice (1.1-inch) if you’d like one thing lighter.
It additionally offers you perks like coronary heart fee variance (HRV) readings for stress knowledge and higher Physique Battery scores, Pacepro, race-adjusted coaching plans, multisport modes for triathletes, acute load knowledge to evaluate your weekly load in opposition to your physique’s optimum vary, and a bunch of different new perks that the older 745 processor cannot deal with.
Should you do not care about music storage, the Forerunner 255 wins. Should you do care, you possibly can technically select the Forerunner 745 to avoid wasting $50, however the $299 Forerunner 255 Music ($100 off) is a way more future-proofed buy that is most likely price spending just a little further.
In any other case, I’ve gathered the opposite finest Garmin Cyber Monday offers nonetheless reside, together with different Forerunner fashions just like the 265 and 965 that’ll provide you with higher perks than both the 255 or 745, however for a a lot increased worth.
