A study of 227,860 nights of wearable data found that bedtime consistency is linked to overnight blood sugar stability — even in healthy adults. The data is more specific than most coverage suggests. the5krunner.com/2026/03/13/u... #Ultrahuman #SleepTracking #MetabolicHealth

Peloton workouts now sync natively into Garmin Connect — Training Load, Recovery Time and Training Readiness all update. There's one catch worth knowing before you enable it. the5krunner.com/2026/03/13/g... #garmin #peloton #indoorcycling #garminconnect

Garmin Body Battery scores 5–100 using continuous HRV analysis. Sleep is the only way to substantially recover it — a full quality night adds 40–60 points. Alcohol suppresses overnight HRV, so the algorithm reads it as stress the5krunner.com/garmin-featu... #garmin #bodybattery #garminrunning

Garmin PacePro sets a different target pace for each km of a race based on the gradient — slower on climbs, faster on flats On flat courses, it adds nothing. On hilly ones, it's the difference between blowing up and finishing to plan. the5krunner.com/garmin-featu... #garmin #garminrunning #running

Suunto has just opened SuuntoPlus to any developer — previously a closed, curated store. The gap with Garmin Connect IQ just got narrower. the5krunner.com/2026/03/11/s... #Running #Suunto #WearableTech

Your Garmin shows a number mid-run that most athletes ignore — or misread. Performance Condition explained in full: what it measures, what distorts it, and when to act on it. the5krunner.com/garmin-featu... #Running #Garmin #TrainingData

Most smartwatch brands claim accuracy. A 2026 meta-analysis of 39 studies puts numbers on it — and the results for Fitbit and Samsung are uncomfortable reading. the5krunner.com/2026/03/10/g... #Garmin #AppleWatch #smartwatch #running

Garmin says your marathon time. Your legs say otherwise. Here is why the prediction is structurally optimistic at longer distances — and what it is actually good for. the5krunner.com/garmin-featu... #Running #Garmin #MarathonTraining #RunningTech

Maurten's bicarb system costs £15 a serving. Is the hydrogel delivery mechanism worth it — or is baking soda just as effective? Race-tested verdict: the5krunner.com/2026/03/09/m... #Duathlon #Maurten #RaceNutrition #SportsScience

Suunto sued Garmin over five patents. Garmin responded with 218 pages and five counterclaims. One of those counterclaims involves a flashlight. The stakes are a US sales ban on Garmin's core watch range. the5krunner.com/2026/03/09/s... #Garmin #Suunto #SportsWatches #GPSWatch

Garmin's Daily Suggested Workouts picks your session each day — easy run, tempo, or intervals — based on Training Load and Recovery Time, not a fixed schedule. Wrist HR errors corrupt the whole system. the5krunner.com/garmin-featu... #garmin #garminrunning #running

Tri-band GPS is already on wrists. Quad-band is coming. Here is what it means for your Strava tracks, your pace data, and when Garmin gets there. the5krunner.com/2026/03/06/t... #GPS #Garmin #GNSS #Running

Eight Sleep just hit a $1.5bn valuation — but the more interesting story is who invested and why. The bed may only be the starting point. the5krunner.com/2026/03/05/e... #EightSleep #SleepTech #HealthTech #Pod5

Garmin Recovery Time is EPOC-based — it measures cardiovascular stress, not muscle damage. A hard interval session can generate the same figure as a long run. Heat and dehydration inflate it. the5krunner.com/garmin-featu... #garmin #garminrunning #trainingload

Oura's fourth acquisition in 12 months. Doublepoint brings gesture-driven AI to the ring — and the deal says as much about IPO positioning as it does about product. What it means for the $11B wearable play: the5krunner.com/2026/03/05/o... #OuraRing #WearableTech #HealthTech #Running

Garmin Training Effect scores aerobic and anaerobic stimulus separately on a 0–5 scale after each session. The aerobic score is driven by peak EPOC — a brief hard effort scores lower than sustained intensity at the same peak. the5krunner.com/garmin-featu... #garmin #garminrunning #trainingload

Garmin Training Load is a rolling 7-day sum of physiological stress, calculated from EPOC generated by each recorded activity. A dropped load figure after a rest day is the window rolling, not fitness declining. the5krunner.com/garmin-featu... #garmin #trainingload #garminrunning

Garmin confirmed 3,000 inReach rescues in 2025. Hikers still dominate — but a new category just entered the top ten for the first time. The Fenix 8 Pro changes what happens after you press the button. the5krunner.com/2026/03/04/g... #Hiking #GarminFenix #SatelliteSOS

Whoop plans to hire 600 people in 2026 — framed explicitly around an IPO. But there's a contested headcount figure that changes the story significantly. the5krunner.com/2026/03/04/w... #Whoop #WearableTech #IPO #Running

Google's March Pixel Drop quietly signals where Pixel Watch is heading — and it's further from your phone than you might expect. the5krunner.com/2026/03/04/p... #PixelWatch #WearOS #Gemini #Android

Garmin Training Status has seven labels — Productive, Maintaining, Peaking, Recovery, Unproductive, Overreaching, Detraining. Unproductive means load is high+VO2 max hasn't responded yet, not that training is wrong. Full breakdown: the5krunner.com/garmin-featu... #garmin #garminrunning #trainingload

Garmin's Training Readiness pulls from 6 inputs — but most athletes only manage one of them. The others quietly drag the score down each morning. the5krunner.com/garmin-featu... #garmin #running #garminforerunner

Your Garmin's treadmill pace is wrong. Not slightly — structurally wrong. RunBridge fixes it at source, no calibration required. the5krunner.com/2026/03/03/r... #Running #RunBridge #IndoorRunning #Garmin

Garmin's unlimited battery life isn't a marketing claim — it's the output of six specific engineering decisions made over six years. None of them was dramatic in isolation. The full breakdown: the5krunner.com/2026/03/03/g... #Garmin #UltraRunning #GPSWatch #SolarCharging

Garmin's wrist-based respiration rate measures breaths per minute during sleep — normal for a fit adult is 12–20. A reading above 20 over several nights often signals fatigue or early illness before other symptoms appear. the5krunner.com/garmin-featu... #garmin #garminwatch #running

Garmin max heart rate (HRmax) is the highest bpm your body can sustain in an all-out effort, and it sets the top anchor for every HR zone on your watch. Many models can auto-detect HRmax during hard efforts rather than rely on 220-age. the5krunner.com/garmin-featu... #garmin #garminrunning #running

Garmin Fitness Age shows your cardiovascular fitness as an equivalent age based on VO2 max relative to population norms. A 50-year-old with top-percentile VO2 max can see a Fitness Age in the low 30s. the5krunner.com/garmin-featu... #garmin #fitnessage #vo2max #garminwatch

Sapphire crystal is rated Mohs 9 — yet your Garmin watch lens can still scratch. Every repair option ranked by risk, from DIY polish to Garmin's out-of-warranty service. the5krunner.com/2026/03/02/g... #Garmin #Running #GorillGlass #Smartwatch

WHOOP's new Passive MSK update changes how strength training counts toward your Strain score — automatically, no logging required. One methodological question remains open. the5krunner.com/2026/02/28/n... #StrengthTraining #WHOOP #WearableTech #MSK

WHOOP's February 2026 heart rate update is more than a patch — it's a rearchitected algorithm. One detail most reviews will miss: the data in your app may differ from what your bike computer recorded. the5krunner.com/2026/02/28/w... #WHOOP #HeartRate #Triathlon #Wearables

Photograph a page from Pfitzinger or Daniels. It appears on your Garmin as a structured workout. Pacier does the part runners have always done by hand. the5krunner.com/2026/02/28/p... #Running #Garmin #TrainingPlans #StructuredWorkouts

4iiii just relaunched the Viiiiva as a v2.0. 540-hour battery, stripped-back feature set. One competitor beats it on battery by a wide margin — and costs less. the5krunner.com/2026/02/26/4... #cycling #HeartRateMonitor #4iiii #ANTplus

Four weeks. 100km+. Tunnels, trails, tall buildings. The Huawei Watch GT Runner 2 has the second-best GPS score I've ever recorded — but there's a catch. the5krunner.com/2026/02/26/h... #Running #HuaweiWatch #GNSS #SportsWatch

Ride with GPS has launched a free Community Photo Layer — 300,000 geolocated rider photos in the route planner. How does it compare to Komoot Trail View and Strava? We looked at all three. the5krunner.com/2026/02/26/r... #cycling #RideWithGPS #routeplanning #gravelcycling

Lactate monitoring without a finger prick. PointFit's PF-Sweat Patch reads lactate continuously from sweat in real time — the first consumer wearable to attempt this. Currently in beta. Full breakdown: the5krunner.com/2026/02/26/n... #Endurance #PointFit #LactateThreshold #SportsScience

Oura just built its own health model — trained on clinical science, tuned specifically for women, and grounded in your body's data. This is different. the5krunner.com/2026/02/24/o... #OuraRing #WomensHealth #Fitness

Garmin's Q1 2026 update is live — gear tracking, Course Planner, Varia voice alerts and more. Not every watch gets everything. Check the compatibility tables before assuming yours does. the5krunner.com/2026/02/24/g... #Garmin #Running #Cycling #GarminConnect

Garmin's most expensive trail watches have had broken trail navigation since December. Every update since has left it unfixed. the5krunner.com/2026/02/23/g... #TrailRunning #Garmin #fenix8 #Enduro3

Garmin cut the fenix 8 MicroLED by $300 — quietly, five months after launch, with no announcement. The earnings call context makes the timing hard to ignore. the5krunner.com/2026/02/23/g... #Garmin #fenix8 #Ultrarunning #Triathlon

Garmin now shows live battery status in the device list. Apple has done this natively since 2020. The gap — and what it reveals about Garmin's app priorities — is worth reading. the5krunner.com/2026/02/23/g... #Garmin #GarminConnect #RunningTech #Triathlon

Strava just added 5 new sports. Padel, cricket, dance — fine. But the timing, weeks after a confidential IPO filing, tells a more interesting story. the5krunner.com/2026/02/22/s... #Strava #Running #Padel #IPO

Garmin's 21.25 update for the Fenix 8 and Tactix 8 is more substantial than the changelog suggests. One addition finally answers where your battery actually goes. the5krunner.com/2026/02/21/g... #Garmin #Fenix8 #Multisport #FirmwareUpdate

Ferrari. The Lions. The Ryder Cup. Al Nassr. Whoop's elite sport push is accelerating — and Garmin is now readying its response. the5krunner.com/2026/02/21/w... #F1 #Whoop #Garmin #WearableTech

Physical therapists are seeing multiple Runna injury cases weekly. But is the app to blame, or is AI coaching simply not ready yet? A coach who tested it firsthand gives a verdict. the5krunner.com/2026/02/21/r... #Running #Runna #MarathonTraining #AICoaching

Garmin didn't buy MyLaps just for race timing. Cliff Pemble's Q4 earnings call revealed an ambition that runs from race discovery to results in Garmin Connect. The strategic logic is worth understanding. the5krunner.com/2026/02/20/g... #Garmin #MyLaps #Running #Triathlon

Garmin's CEO was asked directly about non-watch form factors on the Q4 earnings call. His answer was not a denial. One new product is almost certain. One is widely rumoured but probably impossible. One is something else entirely. the5krunner.com/2026/02/20/g... #Garmin #CIRQA #Wearables #Running

A Garmin watch identified a depression subtype that clinical interviews missed entirely. The findings are real but the limitations matter as much as the headline. the5krunner.com/2026/02/20/g... #Garmin #HRV #MentalHealth #Wearables

Garmin grew fitness revenue 33% in 2025. The overall market grew at mid-single digits. Garmin's CEO explained exactly where those extra customers are coming from — and it's a two-front story. the5krunner.com/2026/02/19/g... #Garmin #Running #WearableTech

Garmin scrapped its Fenix outdoor segment target after a Q3 miss sent the share price down 8% vs the NASDAQ. Three months later, the reporting mechanism is gone. the5krunner.com/2026/02/19/g... #Garmin #Fenix8Pro #WearableTech
