I ran the New York City Marathon carrying seven health trackers to see how they examine, and I left with a number of favorites. I obtained lots of unusual seems, but when disgrace is the value to pay for locating the perfect health tracker for working a marathon, so be it.
While coaching for the race, I used 10 completely different trackers in complete — deep breath — the brand new Apple Watch Ultra 3 (which changed my Apple Watch Ultra 2, which changed my Apple Watch SE), the Garmin Forerunner 570, the Whoop MG, the Pixel Watch 4 (in addition to the older Pixel Watch 3), the Suunto Run, the Oura Ring 4, and the Fitbit Charge 6.
In the top, I ran the marathon utilizing the seven most up to date fashions of our high contenders. I used to be most impressed by the Whoop MG, Garmin Forerunner 570, and the Apple Watch Ultra 3. The extra inexpensive Suunto Run additionally has lots to supply runners.
I additionally needed to seek out probably the most dependable health trackers for marathon coaching, so throughout every week of my coaching, I centered particularly on one tracker or smartwatch. To guarantee the perfect knowledge assortment attainable, I additionally wore it in the course of the day and evening outdoors of my exercises to check its battery life and restoration knowledge assortment.
While I centered on a special tracker every week, I wore all seven fashions throughout all of my exercises throughout all the 18-week coaching season. In complete, I ran 508 miles, had 30 weightlifting periods, rode a motorcycle for 110 miles, and practiced yoga or Pilates about as soon as every week.

Reader: It was humiliating, and I did all of it for you.
I needed a wearable that had a snug design, easy-to-understand exercise metrics, helpful restoration metrics, a protracted battery life, and was definitely worth the value. I needed it to assist me practice, recuperate, and run the marathon. So, here is every little thing I discovered throughout my 508-mile quest to seek out the perfect health trackers for working a marathon.
Best well being tracker for marathon coaching
My choose: Whoop MG 4.0

I wore the Whoop MG for 18 weeks and 500 miles of coaching.

The new Whoop MG is an extremely comfy, minimalist tracker designed for well being and restoration slightly than in-the-moment efficiency, and I actually favored it.
Its delicate, light-weight band feels nearly invisible, and since there’s no display screen, you’re blissfully free from fixed notifications or distractions — one thing I didn’t understand I wanted till I had it.
That mentioned, the shortage of show, GPS, and coronary heart fee suggestions throughout exercises makes it primarily ineffective for dwell coaching metrics, akin to tempo or distance. So, like with many well being trackers, you may seemingly must additionally use a secondary health tracker to get real-time knowledge in your run, together with tempo, coronary heart fee, and elevation.
Still, the post-workout insights are spectacular: you’ll be able to actually see spikes in pressure or stress — even pinpointing moments like a fall or robust interval — making it really feel private and validating.
The restoration metrics are the place Whoop actually dominates. Its journal function is versatile, permitting you to log habits like alcohol use, weed, and even consuming beans, all of that are correlated with sleep, stress, and restoration. The sleep monitoring is top-tier, breaking down phases, disturbances, and restoration readiness into clear, actionable knowledge that helps you determine when to push or relaxation. The battery system is genius — a slide-on charger means you by no means must take it off, not even within the bathe.
While the subscription mannequin is financially irritating, Whoop’s depth of restoration knowledge makes it arguably the perfect device for understanding your physique.
Also examined: Oura Ring 4

The Oura Ring might be the best-looking wearable I attempted throughout coaching season. It’s smooth, comfy, and surprisingly unobtrusive, and it excels at restoration monitoring. Obviously, very like the Whoop MG, this should not be the one wearable you utilize for marathon coaching — there is no exercise knowledge, as a result of there is no display screen, and it has no capacity to offer dwell coaching suggestions like tempo or coronary heart fee. It gives nearly no helpful knowledge throughout or instantly after exercises, making it extra of a wellness tracker than a efficiency device.
It by no means pinched or grew to become uncomfortable — although I wouldn’t advocate carrying any rings in any respect whereas lifting weights. When it involves exercise metrics, the Oura Ring merely isn’t constructed for dwell coaching suggestions.
However, the place it actually shines is in restoration monitoring. It screens key well being indicators akin to coronary heart fee, coronary heart fee variability, physique temperature, sleep high quality, and common exercise, delivering persistently insightful knowledge that helps you perceive your readiness and restoration tendencies.
It’s additionally surprisingly helpful for cycle monitoring (in case you’re into that type of factor), providing correct temperature-based insights. The Oura Ring 4 battery life is great — it may possibly simply final a number of days, and I merely cost it whereas showering with out ever working into low energy points.
Though it’s expensive and requires a subscription, it’s HSA/FSA eligible, which helps. Overall, the Oura Ring is an distinctive sleep and restoration tracker, greatest paired with a devoted health machine for coaching.

Best life-style smartwatches for marathon coaching
My choose: Apple Watch Ultra 3

The Ultra 3 simply beat different smartwatches, but it surely’s additionally expensive.
Credit: Joe Maldonado / Mashable
The Apple Watch Ultra 3 is without doubt one of the most superior smartwatches but — highly effective, sturdy, and thoughtfully designed, although not with out its quirks.
Its huge display screen and hefty construct make it really feel substantial on the wrist, however regardless of its dimension, it stays surprisingly comfy, even for sleeping. It’s not the lightest watch on the market, but it surely’s well-balanced sufficient for all-day put on.
During exercises, the metrics are easy however dependable, supplying you with correct readings of coronary heart fee, tempo, and time, with the choice to plan structured exercises instantly on the watch. You can pause your run by clicking any two buttons without delay, and begin a brand new phase by clicking the orange button. I recognize how simply I can change between media, segments, and exercises.

Post-run knowledge is primary in comparison with devoted working watches, however nonetheless lots for informal runners. The restoration and well being monitoring options are strong — it tracks sleep, cycle phases, blood oxygen, respiration, and cardio health, and you’ll manually add knowledge on vitamin, remedy, or signs for a extra holistic image.
Battery life is the perfect of any Apple Watch, lasting by a full marathon with out dying and recharging rapidly. For occasion, I wore all of it day and all evening, throughout exercises and journey, however simply charged it whereas I showered, and had no drawback with the battery life.
At $799, it’s by far the priciest watch I examined, however its huge display screen proved unexpectedly helpful throughout my marathon — I may simply learn notes and spot buddies on the course, and even reply to texts mid-race with out lacking a step. For runners who aren’t coaching for a marathon, the brand new Apple Watch Series 11 additionally impressed our Apple professional.
Also examined: Google Pixel Watch 4

If you are on the lookout for an Android smartwatch for working, Mashable has been very impressed with the Pixel Watch 4.

I actually loved utilizing the Pixel Watch 4 for my coaching, but it surely had one big flaw that moved it beneath the Apple Watch Ultra 3 for marathon coaching: it died in the course of the marathon. I by no means had a problem throughout marathon coaching, together with a future that was 22 miles lengthy. So, it is nonetheless among the finest smartwatches for working typically. But in the course of the race itself — which incorporates leaving my house about 5 hours earlier than truly beginning the race, sitting in a comparatively chilly begin village, and working the race — my Pixel Watch 4’s battery died. My Apple Watch SE additionally died in the course of the 2023 New York City Marathon, so I’m not unfamiliar with the ache, but it surely’s not what you need.
However, throughout coaching, I used to be happy with the watch. It’s a stable, well-rounded smartwatch that balances consolation, efficiency, and good integration. It’s light-weight and simple to put on across the clock — comfy sufficient to sleep in, with no irritation or bulk. During runs, it delivers all of the important exercise metrics like tempo, coronary heart fee, and time, displayed on a shiny, easy-to-read display screen that holds up even in direct daylight.
The buttons really feel a bit mushy, however their presence remains to be appreciated for sweaty exercises when touchscreens fall quick. Post-run, the Fitbit app gives deeper insights akin to stride size, step cadence, floor contact time, vertical ratio, and oscillation.
While Fitbit isn’t my favourite monitoring platform, its integration right here is clean and responsive, particularly with the choice to create customized exercises, from interval periods to threshold runs, and even obtain AI-powered day by day run suggestions.
Recovery monitoring is stable, too, with correct sleep scoring that aligns carefully with well being trackers just like the Oura Ring and Whoop.
The battery life (say it with me: boooooo) is meant to final round 48 hours for normal use, which isn’t stellar for hardcore health customers however is ok for a way of life watch, and charging is quicker and extra dependable than earlier Pixel Watches.
At $350, it’s a good worth — significantly in case you already personal a Pixel cellphone.

Best health tracker for working and marathon coaching
My choose: Garmin Forerunner 570

Credit: Joe Maldonado / Mashable
I’m not saying something revolutionary or surprising once I say Garmin is a runner’s watch.
The Garmin Forerunner 570 is without doubt one of the most superior health watches in the marketplace, and it is apparent from the second you put on it for a run. The exercise metrics are nothing wanting unimaginable. During exercises, it covers all of the necessities — tempo, coronary heart fee, time — and presents them clearly on a shiny, easy-to-read show. I do not love the buttons (they are a bit mushy for my style), however they’re responsive sufficient.
Post-run knowledge is the place Garmin actually shines: run/stroll detection, coaching impact, energy output, and working dynamics like vertical oscillation and stride size supply a degree of perception few gadgets can match. It even gives adaptive coaching plans primarily based in your knowledge.
On the restoration aspect, Garmin’s coaching readiness and physique battery options mix sleep, stress, and HRV for actionable insights that rival Oura and Whoop.
Of course, it isn’t with out its drawbacks — beginning with consolation. I struggled with the way it felt on my wrist; throughout a wet run in the course of my coaching block, the band dug into my pores and skin and rubbed it uncooked, leaving it sore sufficient that I couldn’t put on it for the remainder of the day. Other individuals have complained that they’ve gotten rashes from the Garmin, too. You can get new straps which may clear up the difficulty, however boy was it disagreeable.
The battery life is great, lasting as much as 11 days, and whereas the $550 price ticket is steep, it’s straightforward to see why athletes swear by it.
More inexpensive working watch: Suunto Run

Credit: Joe Maldonado / Mashable
The Suunto Run additionally has so, so, a lot knowledge. What makes it barely decrease on the record than the Garmin Forerunner 570 is that it has fewer smartwatch perks than the Garmin does — it would not have the third-party app assist, music, and contactless funds out there on the Garmin and, typically, it feels type of low-cost — particularly the charger.
But I did actually just like the Suunto Run. It delivers an impressively balanced expertise for runners who need dependable knowledge, consolation, and battery life with out overcomplication. Its Velcro strap is light-weight, breathable, and safe — it doesn’t rub, slip, or shift throughout exercises, and it’s comfy sufficient to sleep in, which makes carrying it across the clock surprisingly straightforward.
During runs, the watch focuses on the necessities: tempo, coronary heart fee, and cadence, all displayed clearly on a shiny, easy-to-read display screen. The bodily buttons really feel responsive and satisfying to press, a giant plus once you’re sweaty mid-run.
After exercises, the Suunto app unlocks a deeper layer of coaching metrics, together with coaching load, stress rating, and normalized graded tempo. While not each stat will matter to an informal marathoner, the breadth of knowledge is spectacular and well-organized.
On the restoration aspect, Suunto nails readability: it combines coronary heart fee variability, sleep high quality, and coaching stability right into a single, easy-to-read restoration rating that aligns carefully with outcomes from Oura and Whoop, although HRV readings can differ barely.
The battery life is great, lasting as much as 12 days in smartwatch mode or 20 hours in efficiency mode, so that you’ll hardly ever take into consideration charging. At $249, the Suunto Run is a great, well-priced selection for devoted runners who don’t desire all of the fuss of a sensible watch however do need all the information of a working watch.
Also examined: Fitbit Charge 6

Good for counting steps, however not far more.
Credit: Joe Maldonado / Mashable
The Fitbit Charge 6 is the least costly choice I wore, and it exhibits. It’s light-weight, however do not let that idiot you — it is a comparatively uncomfortable tracker compared to the opposite trackers I examined. In reality, after two nights of sleeping with it on, my wrist was bruised.
During exercises, it struggles to maintain tempo with extra superior health watches. The GPS accuracy is inconsistent, overestimating distance on one run and underestimating on the subsequent, which throws off tempo knowledge — a dealbreaker for critical runners. It additionally would not monitor elevation acquire, which is a crucial a part of coaching for a very hilly race just like the New York City Marathon.
Mid-run readability isn’t splendid, and the reference to my cellphone dropped greater than as soon as, however coronary heart fee monitoring shines — responsive, correct, and enhanced by useful haptic alerts once you shift zones.
Recovery monitoring is surprisingly sturdy, providing clear sleep scores and resting coronary heart fee knowledge that really feel well-calibrated for common wellness, even when not probably the most detailed. The actual standout, although, is battery life, which simply lasted a full week with heavy use — actually spectacular for a tool at this dimension and value level.
At $159, the Charge 6 delivers stable worth for on a regular basis athletes who need the very least. If you are on the lookout for the perfect health tracker for working for inexperienced persons, it is a finances choose value contemplating. For marathon coaching, it may possibly’t sustain. It’s successfully a elaborate pedometer, and also you could be higher off shopping for a type of.

After 500 miles, what would I like to recommend to a pal?
So, after 18 weeks of coaching, 500 miles, and so, so many humorous seems (that is what occurs once you put on seven health trackers on the identical time), what did I determine?
Here’s what I’d advocate to a pal coaching for a marathon: I’d put on the Whoop MG for well being monitoring, significantly throughout coaching and restoration. I’d put on the Suunto Run throughout coaching, except I had some huge cash to play with, after which I’d get a Garmin Forerunner 570. If I used to be particularly working the NYC Marathon and was nervous about discovering individuals, I’d preserve the Apple Watch Ultra 3 on my wrist for the marathon.
For now, I believe I would go with none machine for a number of weeks. Free me from the information.
