Runners put numerous thought into their exercises, contemplating issues like how far they will run, how briskly they will run, whether or not they are going to do a gradual distance run or an interval exercise. But one factor leisure runners hardly ever bear in mind is the floor they will be operating on. From asphalt roads to dust 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 greatest floor for operating? We broke down the consequences of the most typical choices.
How completely different surfaces affect the consequences of operating
The floor you run on can both buffer or enhance the influence of every stride in your physique, relying on its stiffness and levelness, says William Charschan, DC, a licensed sports activities doctor, the proprietor of Charschan Chiropractic and Sports activities Damage Associates, and the previous medical director for USA Track and Field in New Jersey.
However there are a selection 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 larger ranges of floor influence,” he says. “If a runner is unable to run sooner and is caught at 10.5 or 11 minutes, the bottom influence might be larger.”

That stated, irrespective of your tempo, completely different operating surfaces can place completely different sorts of stress on your musculoskeletal system, and alter your threat of accidents.
Asphalt
Most roads and bike paths are fashioned from asphalt, making it one of the vital frequent surfaces we run on. However Dr. Charschan says that the surface temps and solar publicity can change how asphalt impacts our our bodies.
“Asphalt is a forgiving floor, particularly because it heats up—however too scorching, 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 tender. 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 frequently, however it’s not 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 enhance the chance of accidents like stress fractures and shin splints.
When you dwell in a metropolis with a number of concrete sidewalks, attempt to restrict the frequency and length of runs on them; search for trails or grass alongside the sidewalk, or hop into the street if it is protected to take action—even asphalt has a bit extra give than concrete.
Grime trails
Trail running has elevated in reputation as a good way to get away from the hustle and bustle of site visitors and join with nature. Working on dust trails can also be gentler on the bones and joints as a result of 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 street operating as a result of a path will not be as easy and even.
“Because of the uneven terrain, a powerful decrease physique is required to keep away from sprains from stepping on rocks and such, [but] trail shoes provide improved traction,” says Dr. Charschan. “The dust 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 more durable in colder climate, which can end in extra influence points.”
Whereas traumatic accidents like sprains are extra frequent in path operating than on flat roads, some analysis has proven that chronic injuries are less prevalent (doubtless as a result of want for extra diverse 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 dust trails; nonetheless, rocks may be slippery and may 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 might be larger when operating on rocky trails versus dust trails. You’ll want to 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 home treadmills and most commercial treadmills. This helps to soak up influence shock and scale back joint stress relative to operating on the street.
Working 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 approach to mitigate that threat is to range the incline and the pace so that you simply change up your operating type and the muscular tissues labored.
In case you are planning to switch your treadmill coaching to street operating for an upcoming race, research suggests that it is best to set the incline on the treadmill to about one p.c to be able to greatest mimic the metabolic and physiological calls for of operating outdoors. It is because there’s restricted air resistance when operating indoors, and the treadmill belt is pulling you alongside quite than you needing to generate the entire propulsive power with your personal muscular tissues.
Working tracks
Most trendy running tracks are created from a vulcanized rubber that’s glorious for absorbing shock whereas nonetheless selling sufficient power return to be responsive for quick operating.
“Most operating tracks are manufactured from a cloth designed to mitigate shock,” says Dr. Charschan. Nonetheless, when you’re operating on the monitor frequently, it would be best to reverse the course on alternate days, he suggests. Working the identical course the entire time, particularly for lengthy runs and exercises, could cause stress in your hips and ankles, notably if the monitor 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 pace coaching could do exercises on this forgiving floor.
“This can be 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 tender as grass and sprains like turf toe can occur.
Grass
Working on grass is typically beneficial as a gentler different to street operating. “Grass has extra give to it, however concentrate on divots and different pits within the floor that may trigger an harm, equivalent to a sprained ankle,” says Dr. Charschan. “It additionally may be a lot softer when moist.” (Learn: muddy.) He provides that whereas many sports activities use manicured grass lawns, your typical grass discipline is just too uneven to be supreme for operating.
Sand
When you’ve ever run on the beach, you’re doubtless effectively conscious that operating on dry sand could be very tough as a result of the sand strikes beneath your toes as you push off. This reduces operating effectivity, since power is misplaced to the transferring sand. Which makes it a difficult cardio exercise, and a chance to strengthen completely 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 contemplate 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 is able to provide extra stability to push towards.
Boardwalks
If there’s a boardwalk alongside the seaside, Dr. Charschan says this could be 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 toes,” notes Dr. Charschan.
It’s also possible to discover boardwalks in some group parks or newbie strolling trails.
The perfect floor? A number of surfaces
As with most coaching ideas integral to the game of operating, various your operating surfaces is the easiest way to supply your muscular tissues, joints, bones, and connective tissues completely different stresses whereas mitigating the dangers of operating an excessive amount of on one sort of floor. Selection not solely helps forestall overuse accidents, however it would naturally power you to strive completely different operating routes, which will even assist forestall boredom—and plateaus in your progress.
