Zone 2 running<\/a> is supposed to be easy. These relaxed, conversational efforts should make up the bulk of a solid training plan<\/a>, building the aerobic base<\/a> that supports every mile to come. So why can keeping your effort level there feel so frustratingly hard?<\/p>\n

For plenty of runners, heart rate climbs out of zone 2 even when their pace feels totally manageable.<\/p>\n

Sometimes the problem is the numbers: The formula or method you\u2019re using to set your zones may not reflect your body. Other times, it\u2019s less scientific\u2014your brain, and maybe your ego, is nudging you to run just a little faster than you should.<\/p>\n

To help you troubleshoot your zone 2 runs, we spoke with a sports cardiologist and an endurance coach who uses heart rate training<\/a> with his athletes. They explain what might be throwing off your effort, how to calculate your zones more accurately, and the best strategies to optimize the easy running that delivers big benefits.<\/p>\n

Measure Your Max Heart Rate<\/p>\n

To figure out your heart rate zones, you have to first know your max heart rate<\/a>.<\/p>\n

The old, often-quoted formula to find it is to simply subtract your age from 220. But that equation is mostly outdated, especially for runners, says Trevor Connor, exercise physiologist, coach, and CEO of Fast Talk Labs<\/a> in Boulder, Colorado. \u201cThe 220 equation every once in a while gets someone\u2019s heart rate max right, but it\u2019s a gross estimate,\u201d he says. \u201cYou can take two people the same age and their heart rate max could vary by 40 beats, particularly in an athletic population.\u201d<\/p>\n

Other formulas exist and are slightly more nuanced, such as 208 minus 0.7 multiplied by your age. This method can be more accurate, but often not very precise for runners.<\/p>\n

One reason, Connor says, is because max heart rate tends to decline less with age in longtime endurance athletes. \u201cThey can maintain their max heart rate for a long time,\u201d he explains. Plus, formulas don\u2019t take into account factors such as overall fitness level, genetics, and sex.<\/p>\n

For a much more accurate number, look at your heart rate during an especially tough workout or race. \u201cOften when people run a 3K or 5K race, toward the end, they should be hitting their heart rate max,\u201d says Tamanna Singh, MD,<\/a> clinical cardiologist and codirector of the Sports Cardiology Center at Cleveland Clinic in Ohio. (As long as you\u2019re going at max effort, rather than just running for fun!)<\/p>\n

The best way to measure your heart rate on your own is with a chest strap or an arm strap<\/a> during a workout or race, says Singh. However, she notes that smartwatches have gotten much better at recording heart rate than they were even just a few years ago (and research<\/a> backs that up).<\/p>\n

To measure heart rate during a workout, Connor suggests doing seven to eight minutes at a zone 2 or 3 effort to warm up. Then do a time trial by running one mile (or just five minutes) starting at threshold pace<\/a> and increasing that effort until you reach your absolute maximum intensity, like you cannot go any longer. (He also suggests doing this with a partner so you can push each other and really hit an all-out sprint!)<\/p>\n

Consider Going to a Lab<\/p>\n

If you want to get precise, the most accurate way to gauge your max heart rate is to have it professionally measured in a lab. Testing will involve exercises with \u201ca slow, graded increase either in pace or in incline on the treadmill,\u201d while you wear EKG sensors on your chest, notes Singh.<\/p>\n

Along with your max heart rate, the lab should be able to give you other stats like your lactate threshold 1 (LT1, a.k.a., your aerobic threshold, when lactate begins to rise) and lactate threshold 2 (LT2, your anaerobic threshold, when you can no longer maintain a steady state), says Connor.<\/p>\n

Just make sure to look for a lab that specializes in athletes because those that primarily cater to a sedentary population won\u2019t necessarily provide you with the information you want, Connor explains. \u201cTheir tests are often designed more to detect arrhythmia, signs of incompetence, or focus on health outcomes,\u201d says Connor. He suggests you ask athletes and coaches in your area if they can recommend a lab that works with runners.<\/p>\n

Zero In on Your Correct Zones<\/p>\n

Whatever way you break down your training zones, remember that zone 2 should be an easy effort\u2014usually around 3 to 5 on a scale of 1 to 10 rate of perceived exertion (RPE<\/a>), with 10 being maximum effort, says Connor.<\/p>\n

For heart rate, many people use the five-zone model that defines zone 2 as 60 to 70 percent of your max heart rate.<\/p>\n

Another way to determine zones based on heart rate, which both Connor and Singh actually prefer over the normal max heart rate calculation, is called the Karvonen method<\/a>. This calculation uses your heart rate reserve, which is your max heart rate minus your resting heart rate<\/a>.<\/p>\n

After determining your heart rate reserve, you multiply the number by the percentage of the zone you want to hit (60 to 70 percent for zone 2), then add your resting heart rate again. The result is your heart rate range for that zone.<\/p>\n

\"\"<\/p>\n

Karvonen Method Example Calculation<\/p>\n

Here\u2019s how it would look if your max heart rate is 180 and your resting heart rate is 50:<\/p>\n

180 (MHR) \u2013 50 (HRR) = 130130 x 0.60 = 78130 x 0.70 = 9178 + 50 = 12891 + 50 = 141<\/p>\n

Your zone 2 range would be 128 to 141.<\/p>\n

While formulas are certainly useful in a pinch, once again, the most reliable way to pinpoint your heart rate zones is using data from a lab test. \u201cYou can use percentages, but it\u2019s different for everyone,\u201d says Connor. \u201cFor example, a sedentary person, their LT1 or top end of zone 2, is going to be somewhere around 65 percent of their max. But for an elite runner, their LT1 can be upward of 80 percent of their max.\u201d<\/p>\n

Connor prefers to determine zones based on someone\u2019s LT numbers rather than simply max heart rate, as it\u2019s much more accurate and based on your physiology rather than a generic formula. He then uses a three-zone model based on an athlete\u2019s LT1 and LT2\u2014where zone 1 is heart rates up to LT1, zone 2 is between LT1 and LT2, and zone 3 is above LT2.<\/p>\n

Take Watch Data With a Grain of Salt<\/p>\n

Although smartwatches<\/a> or chest or arm straps tend to be pretty reliable in terms of tracking your heart rate, keep in mind that the time they say you spent in each of your zones during a workout isn\u2019t gospel.<\/p>\n

For instance, if your watch sets your default zone 2 based on 60 to 70 percent of your max heart rate, but you\u2019ve determined that your max heart rate or zone 2 is higher, the numbers might not reflect the effort of your run.<\/p>\n

If the numbers your watch sets for zone 2 don\u2019t track with what you\u2019ve found your heart rate to typically be during truly easy-effort runs, you can either ignore them or go into your device\u2019s settings and manually enter what numbers are the high and low range for each of your zones.<\/p>\n

Look at Your Heart Rate Trends<\/p>\n

Keep in mind that your heart rate zones fluctuate from day to day, so there\u2019s no reason to freak out if you find you can\u2019t stay in zone 2 for a day or two.<\/p>\n

\u201cHeart rate trends are more important than the isolated data points from one specific run,\u201d says Singh. \u201cIf you\u2019re usually in the 140-to-150 range on easy runs<\/a> but one week you notice you\u2019re getting up around 160 to 170, you might think about why\u2014whether you\u2019re tired<\/a> or getting sick, or you\u2019ve had a couple of late nights or have been drinking alcohol<\/a> more often,\u201d she says. Those extra factors can be the tipping point that makes your heart rate tick up more than usual.<\/p>\n

Writing in a journal about how your runs go and information about things like your stress, anxiety, hydration, any allergies or illness, etc., can provide insight about what\u2019s affecting your heart rate from run to run.<\/p>\n

Caveat: Only get this detailed if you want to and find it helpful, says Singh. \u201cYou have to ask yourself what kind of a person you are,\u201d she says. \u201cAre you someone who\u2019s going to get caught up in the wheels of all that data? If that\u2019s going to cause you more anxiety or stress or grief, then don\u2019t do it.\u201d<\/p>\n

Be Honest With Yourself <\/p>\n

You don\u2019t have to blindly follow the heart rate numbers on your watch. But before you accept that your heart rate is just naturally higher than the zones dictate, make sure you\u2019re not running harder than you think.<\/p>\n

If every easy run goes above zone 2, try going for a run with a heart rate monitor<\/a>, but without checking your pace. Focus on tapping into a truly easy effort in which you can hold a full conversation<\/a>. (No worrying about how slow you\u2019re going!) Then go back and look at the data to see your pace at zone 2. You might be surprised by how much you should slow down<\/a>.<\/p>\n

Then, remind yourself it\u2019s okay if your heart rate goes above zone 2 on occasion.<\/p>\n

\u201cThere are so many things that can change your heart rate during a run\u2014your thoughts, your excitement, sometimes even the cadence of a song you\u2019re listening to,\u201d says Singh.<\/p>\n

Other factors like caffeine, lack of sleep, or mental burnout can also make your heart rate higher. \u201cIf you felt a run was easy and you\u2019re being honest with yourself, and the effort was where you want it for that day, then trust that data over the heart rate.\u201d<\/p>\n

Connor says older or more experienced runners may find their heart rate readily creeping above zone 2 more often because they don\u2019t want to slow down as much as they should. \u201cMasters athletes can really struggle with finding their correct zones and accepting them,\u201d he says. \u201cPeople need to make sure they\u2019re using realistic numbers. It\u2019s better to err on the side of being a little too easy rather than a little too hard.\u201d<\/p>\n

FOLLOW THESE TIPS FOR SLOWING DOWN ON EASY DAYS <\/a><\/p>\n

Stop Comparing Yourself to Others<\/p>\n

\u201cThe runner next to you is not you,\u201d says Singh. \u201cWe get so influenced by what other people are doing, and it\u2019s easy to think, their zone 2 is 130, so my zone 2 should be 130. But you\u2019re your own person, you\u2019re your own runner. Embrace that and be open to learning more about your running style, your body, how it responds to different stressors and rises up to certain challenges. Once you do that, you can start to see your potential.\u201d<\/p>\n

At the end of the day, cut yourself some slack and try not to overthink your zone on every single run, says Singh. \u201cIf you really try to be a stickler about the percentage range of your zones, it will get frustrating and suddenly you\u2019re just running to hit a zone rather than an effort,\u201d she continues. \u201cThe downside to that is you might be limiting your potential or you might be working harder than you should.\u201d<\/p>\n
