Engo 3: Colour Screen, Garmin Workout Mode, and 20-Hour Battery
Engo has launched the engo3, the latest generation of its heads-up display (HUD) eyewear for runners and cyclists. The headline upgrade is a multi-colour display — a significant step forward from the monochrome screen on the engo2 — with two further improvements that make the case for upgrading. Let’s check them out.
What’s New
The engo3 introduces a colour HUD, bringing intuitive zone red-to-green colour-coding to heart rate, pace, and power data in real time. One glance tells you whether you are on target, with your eyes ahead and no need to check your wrist or handlebars.
The second major addition is a structured workout mode for Garmin owners. The engo3 syncs with your Garmin training session and displays live gauges, interval countdowns, and zone targets directly in the lens.
Battery life has also been extended substantially — from 12 hours on the engo2 to 20 hours, making the engo3 a credible companion for ultra-distance efforts.

engo2 vs engo3 – What’s new? What’s changed?
Also via @JS, the bandwidth seems to be improved, removing lags that happened in engo2 from time-to-time.

Context
2026 will see more and better options for smart glasses and AI glasses. Engo3 is one example, Meta Malibu 2 is another.
Who Should Upgrade
Anyone who trains with structured workouts on their Garmin or zone-based plans will benefit most from the engo3, as will anyone who wants intuitive colour coding in real time. Garmin lovers gain the most — structured workout mode is wholly new and confirmed for Garmin and implied for Apple Watch.
Athletes on the engo2 who rely on Apple Watch should verify compatibility before upgrading, particularly those using Strava Live Segments, which was a specific feature of the engo2’s Apple Watch app and is not referenced on the engo3 product page. Suunto owners should also confirm support on engo3.
Price and Availability
The engo3 is priced at £299.95 for the standard tinted lens and £349.95 for the photochromic version. Shipping begins 31 March.

I have engo v2, it’s a gimmick. Stats are kinda nice when biking, not helpful when running (you don’t look at them much). I used the glasses maybe 4 times – lens quality is cr*p. This tech paired with some Raybans or other decent glasses would be nice. But yeah, due to lenses, even if they improved the “AR” module, definitely not buying.
what kind of lenses did you have? Colored or photochromic? or is it a comment about weight/balance?
its the 1st time I hear such feedback about the lenses (there are plenty other comments around, but never heard about the “lenses”)
Its a pity they focused on bringing interface improvement instead of focusing on miniaturization of the hardware piece. Good news they got rid of sensor waiving.
it will be interesting to see how v3 works with garmin AND Stryd – as i understand it wasnt very smooth and some folks reported delayed refresh of power values on-screen and it made this combination hardly usable.
nice, though an expensive toy I’d like to test, but would be more than happy to save 300 GBPs by simply having a glance at my watches!
I have to disagree with Amadeus – I use engo2 for running and biking and find it pretty useful! Mainly for running, tempo intervals or HR based workouts. It´s really different, if you see your pace and HR in front of you, or if you have to glance at the watch, or wait for garmin to tell you you´re running too fast or too slow…
$449 USD – yikes.
Comments above are right on – this would be great for cycling where I’m usually wearing glasses anyway, but it’s rare that my runs involve glasses – and in the summer those glasses became a blurry mess in no time due to sweat.
I think this is a problem for which there really is no answer – that is until they get to holographic tech that will push an image into your actual field of view in front of you. That’s probably not in our lifetimes right?
Has anyone ever heard of a tool that uses audio tones to indicate zones? I can see using headphones and having a distinct tone to indicate zone 1, or 2 etc. You could even have a sound that repeats “1” or “2” to indicate the zone you’re in. Would that be maddening to hear? Maybe. Or if in an actual workout, it tells you in zone (until you’re not). Seems to me audio is a better use case for this stuff.
I use my Engo 2 for running all of the time.
I can confirm there is a delay at times. After one of the Garmin updates I haven’t had the issues of Stryd connecting to Garmin as a power meter and that being forwarded to the glasses. I have less drift and better at hitting my power target when it is of my front of my eyes compared with looking at my watch.
I am also interested in the Garmin/Stryd workout details to the new glasses.
The5krunner was going down and down, but now yup, this site is just overtaken by bots. Bye! [gone from my RSS]
the spam filter checks for real person comments and filters out many thousands of bot comments.
I can’t guarantee what you see is 100% correct but it’s pretty good. The other info I see shows that real people are commenting.
I guess they didn’t improve HUD technology – in Engo2 I find it’s quite difficult to focus on the screen (that is projected quite close to you) – so you have constantly shift your focus from far away (default from running) to close (like reading a book).
I wish to see numbers somewhere on horizont.
I also noticed the delay when running with Engo2 and it is annoying that the HUD displays things so I have to look to the left with the right eye instead of having the numbers so I can just shift focus a little to see them. If the Engo3 work with Stryd workouts through Garmin I will absolutely still want to try them out. Especially if the lag is a bit lower than it is on the Engo2. It is really nice to see the numbers all the time without looking down on your wrist but if I can get countdown for my intervals and see my target watts and it is color coded it will be a huge upgrade for a Garmin user. Even more so if it is easier to do the whole setup
