It\u2019s easy to catch the marathon bug. Influencers and everyday runners flood social media talking about their training, their accomplishments, and their speedy splits. And when your options range from exciting destination races<\/a> and multiday challenge events<\/a> to the coveted World Marathon Majors<\/a>, it\u2019s easy to get caught up in signing up for 26.2 after 26.2.<\/p>\n

But can you run too many marathons?<\/p>\n

What does a race calendar that brings out your best performances\u2014while still supporting your recovery<\/a> and life outside of running\u2014actually look like?<\/p>\n

We talked to an exercise physiologist and a sports psychology researcher to find out the physical and mental effects of marathoning and how to determine the number of races per year that keeps you motivated and feeling accomplished without overwhelm or burnout.<\/p>\n

How Many Marathons Should You Race in a Year?<\/p>\n

It\u2019s absolutely possible to go overboard on marathoning, Janet Hamilton<\/a>, CSCS, an exercise physiologist and the founder and head coach of Running Strong<\/a>, tells Runner\u2019s World. Many factors play into the number of races per year that best serves an individual, she explains.<\/p>\n

One of the most important to consider? Your overall goal.<\/p>\n

\u201cDo you have some sort of a time goal, like you want to qualify for Boston<\/a>? Or do you just want to be able to say you\u2019ve completed one every month? Those two goals are very different,\u201d she explains.<\/p>\n

Racing a marathon at an all-out effort places much more stress on the body than jogging one at your easy pace. Of course, both efforts still require recovery, adds Hamilton. \u201cBut if you have a specific performance goal, it behooves you to train with that purpose in mind,\u201d she says.<\/p>\n

This means setting aside a full cycle of training to properly base-build<\/a>, add in speed, gradually taper<\/a>, and finally, race. To achieve your best result, you can\u2019t rush any part of this process.<\/p>\n

Hamilton\u2019s guidance for most runners who want to race well is to aim for a maximum of two, maybe three, marathons per year. \u201cCan you get away with more than that? Sure. Some people complete streaks of marathoning<\/a> every weekend,\u201d she says. \u201cBut that can be really hard on your body, physiologically speaking.\u201d<\/p>\n

What Happens to Your Body When You Race Too Often? <\/p>\n

Significant physiological changes occur following a long-duration hard-effort exercise bout such as the marathon, explains Hamilton. This can include weakened immune function\u2014part of the reason many runners come down with a postrace cold<\/a>\u2014elevation of enzymes that indicate cardiac damage, increased levels of the stress hormone cortisol, and a decrease in testosterone levels.<\/p>\n

\u201cGenerally, your body will come back in balance with a proper recovery cycle<\/a>,\u201d Hamilton says. But if you never give yourself a break from racing, it becomes much more challenging for you to fully recuperate. \u201cOver time, this takes a toll on your body. And you might not always be able to necessarily feel it.\u201d<\/p>\n

Some signs, she explains, would only show up in specific blood tests or diagnostic scans, such as an elevated cardiac calcification score, which can increase the risk for heart<\/a> problems. \u201cWe can certainly do blood tests to look for markers of creatine kinase [an indicator of tissue trauma from microtears in the muscle], but how many of us get blood tested after every marathon?\u201d<\/p>\n

Fortunately, you don\u2019t need a lab test to notice every red flag. Some more obvious symptoms<\/a> that you\u2019re overdoing it include persistent fatigue, getting sick more often, trouble sleeping, low mood, decreased motivation, and nagging aches or pains that don\u2019t resolve with rest. You also might find that your usual pace on easy runs feels noticeably harder<\/a> to maintain.<\/p>\n

More and more exercise does not necessarily mean better and better physical fitness, Hamilton says. \u201cAt some point, that correlation between volume and health kind of starts to fall apart,\u201d she says. And that not only goes for physical health but for mental health<\/a>, as well.<\/p>\n

Mental Effects of Running Frequent Marathons<\/p>\n

According to a study<\/a> published in Acta Psychologica, multimarathoners\u2014defined as individuals who had completed at least 100 official marathons\u2014had higher depression and anxiety scores compared with the general population, though still below clinical thresholds. \u201cWe found that high levels of physical activity don\u2019t necessarily equate to good mental health,\u201d says the study\u2019s lead author, Leo Lundy<\/a>, PhD.<\/p>\n

Of the 576 runners in the study, about 30 percent had few or no symptoms of anxiety<\/a> and depression, he explains. However, about 25 percent experienced higher levels than average. \u201cWhat was particularly worrying was that 8 percent\u2014which is a significant percentage\u2014showed signs of severe depression<\/a> or high anxiety, way above what you\u2019d expect in the general public,\u201d says Lundy.<\/p>\n

This doesn\u2019t mean that multimarathoning causes these symptoms; it does, however, show an association. And to understand the full picture, we need to examine the type of individual who is drawn to multimarathoning in the first place, Lundy explains.<\/p>\n

\u201cWhen you look at the type of person that’s attracted to long-distance running<\/a>, two areas of the personality were significant in the research,\u201d he says. \u201cOne was conscientiousness: These individuals love to follow the rules. The other was emotional stability,\u201d which assessed how calm or even-keeled they generally tended to be.<\/p>\n

In psychometric tests, marathoners tended to score very high in conscientiousness but lower in emotional stability, which could correlate to higher levels of depression and anxiety, explains Lundy.<\/p>\n

Enter: the marathon. This race provides exactly the environment that this personality type needs to thrive. \u201cThe marathon<\/a> is very structured: You follow the rules, you turn up on time, and you know what\u2019s going to happen. It\u2019s all very predictable in that regard,\u201d he says.<\/p>\n

Add in the meaningful social connection<\/a> that comes from gathering with fellow runners and the sense of achievement from completing a full 26.2 miles, and the picture becomes clearer: These benefits all help marathoners manage those lower levels of emotional stability. And by providing a reliable framework for them to succeed and belong, the race itself becomes a valuable coping mechanism for underlying anxiety and depression.<\/p>\n

However, racing marathon after marathon can also mean sustained physical fatigue, competition pressure, increased injury<\/a> risk, and sacrificing other aspects of life. So, Lundy explains, if a runner relies too heavily on marathoning and continues despite mounting physical, emotional, or lifestyle costs, it becomes a source of stress<\/a>. As a result, it may contribute to the very symptoms a runner was trying to relieve.<\/p>\n

What If I\u2019m Running Easy\u2014Not \u201cRacing\u201d the Marathon?<\/p>\n

Both mentally and physically<\/a>, the amount of effort you put into 26.2 matters when taking on multiple marathons each year. But for some runners, especially those scoring high in conscientiousness, it can be difficult to toe the line and not give their best effort.<\/p>\n

\u201cAs a coach, I consider the individual runner\u2019s personality: How well will they be able to adhere to just doing it at a training effort when that gun goes off?\u201d says Hamilton. Many runners will want to push the pace beyond an easy jog<\/a>.<\/p>\n

So if someone really wants to do a series of mostly easy marathons, she still advises the majority of athletes to complete no more than four marathons per year.<\/p>\n

But many runners do more.<\/p>\n

Take Lundy himself, for example, who, at age 62, has completed more than four hundred marathons, including seven just this year. Lundy says he still enjoys running marathons regularly, but emphasizes this crucial element: Fast performances<\/a> are not the goal.<\/p>\n

\u201cThe most successful multi-marathoners that I\u2019ve come across are people that run at a sub-maximal level. They really are quite slow, quite determined, some running into the seven-hour ranges,\u201d he says. \u201cThey\u2019re running for lots of other reasons<\/a> besides performance.\u201d<\/p>\n

Some of those reasons? Just to finish, to enjoy the social environment, to travel<\/a>, to stay active and healthy. \u201cI\u2019ve run marathons in close to 25 countries; most of my friends are in running communities, so I see them regularly, and achieving new milestones continues to make me happy. That\u2019s really what drives me,\u201d Lundy says.<\/p>\n

While the marathon gives you a specific goal<\/a>, you don\u2019t have to keep chasing finish lines to reap many of the same benefits Lundy mentions. Running in general supports cardiovascular and cognitive health<\/a> while also providing a sense of fulfillment, connection, and belonging, he says.<\/p>\n

So, you might decide to race 26.2 once, many times, or maybe not at all\u2014the right number of marathons for you is the number that keeps you feeling strong, healthy, and happy enough to keep on running.<\/p>\n
