If you’ve ever woken up with burning quads the day after a hilly race, you can probably blame all the downhill pounding. Although running uphill may feel more difficult from a cardio perspective, going downhill well is challenging—and a lot harder on your body.

Here’s why: Muscles contract in two ways—concentrically (muscle shortens: think picking something up) and eccentrically (muscle lengthens while contracting: think putting that something back down). “Eccentric contractions are much more costly from an energy and wear and tear perspective,” says Dr. Ivo Waerlop, D.C. “Running downhill requires lots of eccentric contraction, especially in the quadriceps and lower leg muscles.” Mastering the downhill with proper form will put less stress on your legs and can help you make up time in your next race.

Form tips for going fast downhill

Lean forward from the hips, not the shoulders. Gravity naturally pulls you downhill. Avoid the urge to lean back and focus on keeping your body perpendicular to the ground. “As you increase speed, move your center of gravity forward with you; not enough and your feet are sliding out from under you, too much and you’re on your face,” Waerlop says.

Use your arms for balance. When running downhill, we don’t need the forward-back arm movement for power like we do on flats and uphills. Although it may look ridiculous in race photos, Xterra world champion Lesley Paterson recommends flailing your arms out to the side for balance. “It can help give your body the control it might need if speed takes over or a sudden change in direction is needed,” she says.

Engage your core. Think of your abs, glutes and back as your stable base that your limbs work around.

“Circle” your stride. Because you don’t need as much power from the knee drive (thanks, gravity!), keep the feet under the body and don’t overstride. “I often do an almost circular motion—especially if on steep terrain—rather than driving the knee straight through in front of the body,” Paterson says. “It allows more extension out the back and a chance to relax some of the muscles in the follow-through.”

Look down the hill, not at your feet. Waerlop says when you look at your shoes, it induces neck forward flexion and actually facilitates your flexor muscles, which “turns off” the hip extensor muscles (glutes, hamstrings, back muscles)—the ones which help keep you upright and neutral— increasing your risk of falling forward.

Imagine hot coals under your feet. Keep contact time as minimal as possible. “I like to feel as though I am ‘dancing’ over the ground, just lightly touching it with my mid-/forefoot and springing right off again,” Paterson says. This is even more important for off-road running, when you need to be more versatile with where you plant your foot and for how long.

Perfect Foot Position

Think of your foot as a tripod, with the three points being the heads of the big and little toes (at the ball line) and the heel. This tripod needs to be level for the foot to function optimally. If you are too much on your heel, your shins need to slow the descent of the foot, which can lead to shin splints. If you land too much on your forefoot, your calves have to work harder to lower your heel and will exaggerate any forefoot abnormality you have in your gait; this will place additional stress on your knees. —The Gait Guys, Drs. Ivo Waerlop and Shawn Allen

Quick Tip

New (or suck) at running downhill? Descend with your feet turned sideways. As you gain skill, point your feet more progressively downhill.
