Runners put a number of thought into their exercises, contemplating issues like how far they’re going to run, how briskly they’re going to run, whether or not they are going to do a gentle distance run or an interval exercise. But one factor leisure runners not often take note of is the floor they’re going to be operating on. From asphalt roads to filth trails, treadmills to operating tracks, what you land on with every stride could make a distinction in how operating impacts your physique.
So, what’s the finest floor for operating? We broke down the results of the commonest choices.
How totally different surfaces affect the results of operating
The floor you run on can both buffer or improve the influence of every stride in your physique, relying on its stiffness and levelness, says William Charschan, DC, an authorized sports activities doctor, the proprietor of Charschan Chiropractic and Sports activities Harm Associates, and the previous medical director for USA Observe and Subject in New Jersey.
However there are a variety of different variables that have an effect on influence, too, he provides. “The physique fashion, flexibility, core effectiveness, and even your trainers can have an effect on influence,” he notes. Your operating effectivity may also make an enormous distinction in how you are feeling and the way a lot work it requires so that you can run.
“For instance, a 9.5-minute mile tempo is less complicated on the physique than an 11-minute tempo and extra environment friendly too, because the slower tempo has increased ranges of floor influence,” he says. “If a runner is unable to run quicker and is caught at 10.5 or 11 minutes, the bottom influence can be increased.”

That stated, irrespective of your tempo, totally different operating surfaces can place totally different sorts of stress in your musculoskeletal system, and alter your danger of accidents.
Asphalt
Most roads and bike paths are shaped from asphalt, making it one of the crucial widespread surfaces we run on. However Dr. Charschan says that the skin temps and solar publicity can change how asphalt impacts our our bodies.
“Asphalt is a forgiving floor, particularly because it heats up—however too sizzling, it may be melty and have an effect on your shoe adhesion, because the darkish floor will warmth from the solar,” he says. “Ideally, operating on asphalt is [best] in cooler climate when the floor has extra give however not too comfortable. Within the winter, like all floor, it’s stiff and absorbs shock much less successfully.”
Concrete
Dr. Charschan says that concrete and cement—that are what sidewalks are usually manufactured from—are very stiff and unforgiving surfaces: “I don’t suggest operating on concrete commonly, however it isn’t affected by climate, humidity, or dampness.”
The danger of doing an excessive amount of mileage on concrete is that the hardness of the operating floor will increase influence stress, which may improve the chance of accidents like stress fractures and shin splints.
Should you dwell in a metropolis with plenty of concrete sidewalks, attempt to restrict the frequency and period of runs on them; search for trails or grass alongside the sidewalk, or hop into the highway if it is protected to take action—even asphalt has a bit extra give than concrete.
Grime trails
Path operating has elevated in recognition as a good way to get away from the hustle and bustle of visitors and join with nature. Operating on filth trails can also be gentler on the bones and joints because of the elevated give of the pure earth in comparison with the relative stiffness of asphalt and concrete. Nonetheless, the muscular demand of operating on trails is bigger than highway operating as a result of a path will not be as clean and even.
“As a result of uneven terrain, a robust decrease physique is required to keep away from sprains from stepping on rocks and such, [but] path footwear provide improved traction,” says Dr. Charschan. “The filth itself is affected by the climate. Dry climate is, in fact, going to make it stiffer and fewer more likely to mitigate shock, and moist climate will soften it. Additionally, these surfaces are tougher in colder climate, which can lead to extra influence points.”
Whereas traumatic accidents like sprains are extra widespread in path operating than on flat roads, some analysis has proven that persistent accidents are much less prevalent (doubtless because of the want for extra different physique actions to run over roots and rocks, and up and down steep hills).
Rocky trails
Dr. Charschan says that the qualities of rocky trails are much like these of filth trails; nonetheless, rocks might be slippery and might usually result in twisted ankles, particularly if these rocks are unfastened.
Rocks are also poor shock absorbers so the influence stress on the muscular tissues, joints, and connective tissues can be increased when operating on rocky trails versus filth trails. Be sure you select path footwear with distinguished lugs for traction, and ample cushion to assist take up influence.
Treadmills
Most treadmills have pretty cushioned operating decks, notably premium dwelling treadmills and most business treadmills. This helps to soak up influence shock and cut back joint stress relative to operating on the highway.
Operating on a treadmill can also be very constant—you will not journey on a department. However that repetitive foot strike can result in overuse accidents. One technique to mitigate that danger is to fluctuate the incline and the velocity so that you simply change up your operating type and the muscular tissues labored.
If you’re planning to switch your treadmill coaching to highway operating for an upcoming race, analysis suggests that you must set the incline on the treadmill to about one p.c so as to finest mimic the metabolic and physiological calls for of operating outdoors. It’s because there’s restricted air resistance when operating indoors, and the treadmill belt is pulling you alongside somewhat than you needing to generate the entire propulsive power with your individual muscular tissues.
Operating tracks
Most trendy operating tracks are made out of a vulcanized rubber that’s wonderful for absorbing shock whereas nonetheless selling sufficient vitality return to be responsive for quick operating.
“Most operating tracks are manufactured from a fabric designed to mitigate shock,” says Dr. Charschan. Nonetheless, should you’re operating on the observe commonly, you’ll want to reverse the route on alternate days, he suggests. Operating the identical route the entire time, particularly for lengthy runs and exercises, could cause stress in your hips and ankles, notably if the observe is banked or the curves are tight.
Astroturf
Astroturf is discovered on the infields of many operating tracks the place soccer, soccer, or different sports activities could also be performed. Though distance runners don’t are inclined to run a lot on astroturf, sprinters or runners doing interval coaching and velocity coaching could do exercises on this forgiving floor.
“It is a cushioned floor many sports activities are performed on. The advantage of it’s that it may be utilized in any climate and these fields don’t want resting,” says Dr. Charschan. However he provides that turf is not fairly as comfortable as grass and sprains like turf toe can occur.
Grass
Operating on grass is typically advisable as a gentler different to highway operating. “Grass has extra give to it, however concentrate on divots and different pits within the floor that may trigger an damage, reminiscent of a sprained ankle,” says Dr. Charschan. “It additionally might be a lot softer when moist.” (Learn: muddy.) He provides that whereas many sports activities use manicured grass lawns, your typical grass subject is just too uneven to be preferrred for operating.
Sand
Should you’ve ever run on the seashore, you’re doubtless nicely conscious that operating on dry sand may be very troublesome as a result of the sand strikes underneath your ft as you push off. This reduces operating effectivity, since vitality is misplaced to the shifting sand. Which makes it a difficult cardio exercise, and a chance to strengthen totally different muscular tissues.
“[Running on sand] pushes the runner right into a midfoot stride and can make the calves sore. Construct as much as this or think about a minimalist shoe that has a low heel (1-4mm within the again) to coach in first earlier than doing this,” suggests Dr. Charschan. One other technique is to start out by operating nearer to the shore line the place the sand is damp from the ocean, which can provide extra stability to push towards.
Boardwalks
If there’s a boardwalk alongside the seashore, Dr. Charschan says this generally is a nice different operating floor that also means that you can take pleasure in operating subsequent to the ocean however in a means that’s gentler on the physique.
“This floor will reply to your influence and bounce again, which makes you are feeling lighter in your ft,” notes Dr. Charschan.
You can even discover boardwalks in some neighborhood parks or newbie strolling trails.
The most effective floor? A number of surfaces
As with most coaching ideas integral to the game of operating, various your operating surfaces is one of the best ways to supply your muscular tissues, joints, bones, and connective tissues totally different stresses whereas mitigating the dangers of operating an excessive amount of on one form of floor. Selection not solely helps forestall overuse accidents, however it would naturally power you to strive totally different operating routes, which can even assist forestall boredom—and plateaus in your progress.
