#Zone Running Explained

Running heart rate zones simplified👇🏼 ZONE 1 - RECOVERY (50-60% Max HR) Zone 1 is very low intensity, breathing should be controlled and a conversation is effortless. It helps promote circulation and recovery without adding additional stress. ZONE 2 - AEROBIC BASE (60-70% MAX HR) Zone 2 is the foundation of everything and helps develop the aerobic system. Effort should feel comfortable and sustainable. Most weekly mileage should be performed here to develop long term aerobic capacity. ZONE 3 - TEMPO (70-80% MAX HR) Zone 3 sits between easy and threshold work. It improves aerobic capacity but creates more fatigue than zone 2 without the specific adaptations of higher intensity training. Often called the “grey zone” as most runner unintentionally train here too often. ZONE 4 - THRESHOLD (80-90% MAX HR) Zone 4 is a sustained hard effort, breathing is heaving and talking is limited to short phrases. This zone improve lactate clearance, sustainable race pace, and threshold speed. ZONE 5 - VO2 MAX (90-100% MAX HR) Zone 5 is high intensity, near maximal effort, and talking should feel impossible. This zone helps improve maximal oxygen uptake, top end aerobic capacity, and running economy at high speeds. It is highly demanding on the nervous system and muscles and should be used sparingly within a structured plan. Control Intensity. Build the base. Layer speed on top.

Stop caring about your watch’s VO₂max ↓ Something that comes up a lot when I talk to runners - whether it’s clients or people sliding into my DMs - is how stressed they get when their watch’s VO₂max drops a point or two. When I tell them I barely even look at that stat, they’re confused. Your watch doesn’t measure ACTUAL VO₂max. It estimates it, using heart rate data and pace from your runs. The algorithm looks at the relationship between your effort (HR) and your speed, and makes a prediction. No gas mask, no lab, no direct oxygen measurement, just an educated guess based on limited data. So if you run in the heat, with a lot of elevation, or have a couple of bad nights of sleep, your watch can think you got worse. To show you how far off it can be, my watch estimated my VO₂max at 54, while my lab-tested value was 61. That’s a 7-point difference, which in practical terms is pretty significant. Does this mean the stat is completely useless? Not entirely. The trend over months can give you a rough signal of whether your aerobic fitness is moving in the right direction, as long as you’re comparing similar conditions. But as an absolute number? Take it with a grain of salt. And even if the number were accurate, VO2max is just one piece of the puzzle. Lactate threshold, running economy, and fatigue resistance are equally important for actual race performance, and none of them show up on your watch face. Two runners with the same VO2max can race very differently because of how well they utilize that ceiling. So it’s much more useful and practical to just look at actual training data (volume, pace, HR,… = REAL training trends) than just this estimation on your watch.

✅A lot of #runners are messing up ⚠️their Zone 2 training. Here’s why: 1. Wrist heart-rate sensors ⌚️ (like those on most smartwatches) are often inaccurate. If you want reliable data, use an external monitor, such as the @corosglobal armband, to get closer to your actual heart rate values. 2. You probably don’t know your true max heart rate. 💗Hitting your 100% max is very hard, and formulas like [220 minus age] are often wrong. That inaccuracy throws off all your zone ranges in apps like Strava. 3.✅When in doubt, keep it simple: Don’t run more than about 2.5 minutes per mile (90 seconds per km) slower than marathon pace, and make sure you can easily hold a conversation because your breathing is still under control. That’s your #Zone2. Follow @higherrunning for more tips🏃🏻🙌 #runningcommunity

Heart Rate Zones: Useful… Only If They’re Yours Ever feel like Garmin/Strava says you’re “training hard” on an easy run? It might not be you, it might be your zones. Heart rate is powerful because it shows internal load: what the effort is costing your body today (fatigue, heat, stress, hills). But if your zones are built from HRmax = 220 − age, they can be way off. One wrong HRmax estimate = every zone shifted… and your training gets mislabeled. How to keep it simple (and accurate): If you don’t know your LT1 / LT2 confidently yet, use Effort (RPE 1–5) to guide training: - 1/5 Very easy, recovery pace, nose breathing, full conversation. - 2/5 Easy, aerobic base, relaxed, can chat easily. - 3/5 Steady, “working but controlled”, short sentences ok. - 4/5 Hard, threshold vibe, only a few words, focused discomfort. - 5/5 Very hard, VO₂ / anaerobic, no talking, short intervals only. Rule of thumb: Do most running at RPE 1–2/5, and keep workouts honest at RPE 4–5/5. Heart rate becomes a check, not the boss until you’ve tested and set your personal zones. #ultras #trailrunning #carrerasdemontaña #ultrarunningtraining #ultramarathon

Why your heart rate can’t stay in zone 2👇🏼 1) YOUR AEROBIC SYSTEM ISN’T DEVELOPED When you first start running, your cardiovascular system simply isn’t efficient. Your body hasn’t yet adapted to delivering oxygen efficiently, so even a slow jog creates a relatively high demand. It’s not that you can’t run easy, it’s that your current “easy” is still physiologically demanding. 2) YOU STARTED TOO FAST Heart rate lags behind effort, if you go out at your “normal” pace, HR will climb 5-10 minutes later and push you into zone 3. Start slower than you think and settle into the run. 3) YOUR HEART RATE ZONES MIGHT BE WRONG Most watches use generic formulas like 220-age. This is population based, not individual. If your true max heart rate differs from the formula, your zones will be inaccurate. You might think you’re in zone 3 when physiologically you’re actually still aerobic. 4) STRESS OR POOR SLEEP Your body doesn’t separate training stress from life stress. Work, lack of sleep, dehydration, and under fuelling will all elevate heart rate response. If your resting HR is higher than normal, your training HR will follow. 5) HEAT AND HILLS INCREASE DEMAND External factors matter. Heat increases cardiovascular strain and hills increase muscular demand, which raises heart rate quickly. In both cases, pace must drop to keep effort consistent.

You trust your running watch to guide your workouts. You look at your wrist and see 180 beats per minute. You feel fine. Your device is incorrect. Optical wrist sensors track blood flow volume. Sweat and cold weather disrupt these sensors. A 2017 Journal of Personalized Medicine study shows optical monitors produce errors during 15 percent of vigorous workouts. The sensor often reads your arm swing rate instead of your pulse. This error is cadence lock. Relying on this flawed number ruins your pacing strategy. You must analyze physical feedback to gauge your exertion. * Perform the talk test during your run. Speaking in complete sentences indicates a low aerobic effort. * Assign a number to your perceived exertion from one to ten. Keep easy runs at a four. * Tighten your watch strap before you start. Secure the device two fingers above your wrist bone to improve sensor contact. * Wear a chest strap monitor. Chest straps measure electrical signals directly from your heart for precise data.

🧠 If you don’t understand heart rate zones, you’re guessing, not training. Most runners either run too hard on easy days or too easy on hard days. Heart rate zones remove the guesswork and tell you exactly how your body is working. ❤️ Heart Rate Zones Explained 🔵 Zone 1 – Recovery 50–60% max HR | RPE 1–2 🟢 Zone 2 – Aerobic Base 60–70% max HR | RPE 2–3 🟡 Zone 3 – Tempo 70–80% max HR | RPE 4–5 🟠 Zone 4 – Threshold 80–90% max HR | RPE 6–7 🔴 Zone 5 – VO2 Max 90–100% max HR | RPE 8–10 📊 How to calculate your max heart rate Simple estimate: 220 minus your age Example: If you’re 30 years old 220 − 30 = 190 max HR 📈 Example heart rate zones (max HR = 190) 🔵 Zone 1: 95–114 bpm 🟢 Zone 2: 114–133 bpm 🟡 Zone 3: 133–152 bpm 🟠 Zone 4: 152–171 bpm 🔴 Zone 5: 171–190 bpm 🏃‍♂️ Why this matters Most runners spend too much time in no man’s land.

Garmin Pro+ chest heart rate monitor v Coros Optical arm heart rate monitor - I both put to the test alongside each other in a sub maximal step test under lab conditions to see if there was any variation in results between the two🫀 The step test included 8x 4 minute stages starting at 10km/hr building upto 17km/hr where the average heart rate from each device was logged during the stage. Probably fair to say the Garmin pro+ or any ECG chest strap is the gold standard in the heart rate monitor game but the Coros arm monitor is probably the most popular device of choice nowadays for comfort reasons but I’ve always been sceptical about the accuracy of the data as it uses the same technology as the wrist sensors which are below par for data accuracy due to poor blood flow at the wrist. You’re gonna heave to watch to the end of the results 😁 Big shoutout to @nuffieldhealth_mihp for allowing me to do this test within a test 👍 #marathonrunner #marathontraining #heartratemonitor

❤️‍🔥 Heart Rate Zones Explained Every run has a purpose but only if you understand what zone you’re training in. Zone 1 = recovery Zone 2 = endurance Zone 3 = tempo Zone 4 = threshold Zone 5 = speed & VO₂ max Each zone trains your body differently. And when you mix them correctly, that’s when progress happens. You’ll often hear that 70–80% of running should be in Zone 2… but if you only run 2 days a week, that might look more like 50% easy and 50% quality work. There’s no one-size-fits-all rule. Your training should match your schedule, goals, and recovery. When planning a program, there’s a place and purpose for every zone. If you want help building a smarter running plan using heart rate zones… comment “HEART RATE” and I’ll reach out.

let me be clear — i run with a watch every day. wearables aren’t the problem. data overload is. your watch can track 40+ metrics, but most of us are drowning in numbers that don’t actually help us run better. pace jumps around with GPS signals. cadence varies by terrain. vo2 max estimates change slowly and don’t inform today’s run. here’s which metrics actually matter: 1️⃣ HRV (heart rate variability) this measures the variation in time between your heartbeats. when it’s high, your parasympathetic nervous system is active and you’re recovered. when it’s low, you’re still stressed from previous training. research shows HRV is one of the most reliable indicators of training readiness. it tells you whether to push hard today or back off — before you even lace up. 2️⃣ resting heart rate trends your RHR baseline matters more than the daily number. a 5-10 beat spike that stays elevated for multiple days often signals overtraining, dehydration, or oncoming illness before you feel symptoms. i’ve avoided getting sick by backing off training when my RHR jumps and stays high. 3️⃣ properly calibrated heart rate zones most runners use the default 220-minus-age formula, which research shows can be off by significant margins for trained athletes. your watch needs 1-4 weeks of consistent wear to establish accurate baselines. without this, every “easy” run becomes too hard and every hard workout becomes too easy. these three metrics are available on almost every watch, from $200 to $600. they’re not flashy. they’re not complex. but they actually inform your training decisions. the insight isn’t in having more data. it’s in knowing which data to trust. #runwithlks #keepshowingup #runner #wearables #garmin

It went slightly up after @thedubaimarathon due to recovery but still pretty happy. Low resting heart rate isn’t about being “fit” in a flashy way. It’s just years of consistent endurance training doing its thing. #enduranceathlete #marathontraining #runningscience #restingheartrate #runnersofinstagram
