There's a lot to love about running. It's cheap to get started, great for torching calories, and works well with nearly any cross-training regimen you may have. But in the ongoing bar bet of which sport is best, we believe cycling is still the overall winner. (And, we think we can prove it.) Here's why.

 
Get Fit & Build Endurance

It's true that running burns more calories per km, but most people can’t run as many kilometres as they can ride, especially if you’re a little out of shape or have some weight to lose. Blame gravity. When you run you need to lift your body weight up off the earth to propel yourself forward. Then you have to come back down, striking the ground and absorbing those impact forces. 

Both of those things make it considerably harder to run 10km than to ride twice or even three or four times as long. Running is also less forgiving of extra weight with every excess kilogram slowing you down. Excess weight makes hills harder on a bike, but on the flats? Because gravity isn’t really a factor, you can motor along with the skinniest of ‘em.

Pain Points

Running beats you up more than cycling, even if you’re hammering super hard. One study that compared trained, competitive cyclists and runners exercising 2 ½ hours a day for three days found that the long distance runners had substantially more muscle damage (between 133% and 404% more), inflammation levels (up to 256% higher) and muscle soreness (87% more) in the following 38 hour recovery period than the cyclists.

“We knew running places more stress on the body, but how much more damage and inflammation there was was surprising and greater than anticipated,” says study author David Nieman, professor of public health at Appalachian State University. “There’s just a lot more muscle trauma involved with running. It’s harder for the immune system to handle the damage.”
