Are You Cheating Yourself by Choosing the Treadmill?

What's Better: the Treadmill or the Open Road?

When it comes to running (and walking), you have two types of people: those who adore the outdoors and those who would rather have their try at the treadmill. I've heard countless reasons from each type of runner on exactly why they choose to run indoors or out, but for the newbie runner, it can be confusing. Which is better? Is there really a big difference between the treadmill and the sidewalk? Which offers a higher calorie burn? What are the pros and cons of each option?

In order to clear up confusion and settle this debate once and for all, we're pitting treadmill running vs. outdoor running. In this head-to-head match, we'll rate indoor and outdoor running's pros and cons on different and important variables. Read on to find out which type of running reigns supreme for you!

Surface
On the treadmill, you run on one surface: the treadmill belt. This is good because it's flat and has some give for your knees, as long as the belt is properly waxed and cared for. On the other hand, the treadmill is flat and, even with an incline, doesn't give your muscles the same variability or challenge that you'd get outside.

Running outside gives you greater variability and challenge because of the changes in terrain and slope, but if you're running on the cement sidewalks or asphalt, running can be very jarring on your knees and joints. When it's wet or icy, it can also be quite risky. Running on a trail or track is best on your body for outdoor running, but depending on where you live, may not be available.

Tips: For those with bad knees, the treadmill or a cushioned running track is probably best. And for those who love the treadmill, don't forget to use that incline button every once in awhile to add some hills into your workout.
Climate
When you run on a treadmill, you pretty much know that the temperature is going to be in the upper 60s or lower 70s. You know what to wear to regulate your body temperature, and there's no wind, rain, snow to battle. But treadmill runners miss out on the sunshine (and the vitamin D it provides) and outdoor experience that so many people crave.

When the weather is a perfect 68 degrees and the sun is shining, it's hard to imagine wanting to run indoors. But when it's dark, cold, rainy or windy, the weather can really play a factor in your comfort level, performance and safety. In the winter, if you're not properly prepared, you can get frostbite, get dehydrated, slip and fall on ice, or even pull a muscle and be stranded miles away from home. Extreme heat also has its risks. And for people suffering from seasonal allergies, outdoor exercise isn't even an option sometimes.

  • Good article. I run both on TM's and outside. I love the outdoors. However, I push myself more on the TM. I have nothing to focus on but the numbers, and so I make myself really work hard. Outdoors I get too distracted by pretty scenery and my own thoughts. So I find a balance between the two works best for me. - 1/13/2013 7:35:22 PM
  • I've been using a treadmill for a Couch-25k program. I think it's a good way to start out because it's easy to track the length of intervals and to adjust the speed from walk to run. Once I'm able to actually run for 3 miles without stopping, I might try the outdoors. It's also my first attempt at running since a bad ankle sprain 2 years ago, and so the 'give' of the treadmill is also a plus, since it likely reduces the irritation on my ankle while I build up muscle. - 1/13/2013 7:30:27 PM
  • Great article, really lays out the pros and cons clearly. - 1/13/2013 4:17:30 PM
  • Treadmill or outdoors - the most important thing is to start off with whichever will keep you going. I definitely agree that a treadmill is 'easier' and it's what I've started off with due to convenience. I try to balance the heavy treadmill use by upping the speed and incline and going hiking/walking on the weekends. - 1/13/2013 1:45:53 PM

    I love the outdoors when it's warm enough to jog or walk. When I am on the treadmill I find that using the incline at the highest level works best for me. I get a great workout and burn a lot of calories. I would much rather do zumba, kick boxiing, step aerobics or something fun. When I first started to exercise it hurt my knees to even walk outside and on the treadmill but I kept pushing myself to just do it. My point is, it doesn't matter weather you walk, jog, run, on a treadmill or outside. Just do something to get you moving and have fun doing it. You're saving your life. Your heart will be stronger, you'll look and feel better about yourself.
    So get moving!!!!!!!!!!! Good Luck..... - 1/13/2013 1:38:25 PM
  • I think if you want to run outdoors, then do it OUT OF TRAFFIC. - 1/13/2013 1:35:00 PM

    I like to walk outside especially at this time of year in Florida. But I resort to a treadmill during some of the worst "dog days" of a hot, humid, Florida summer. I don't run on the treadmill. Both places that I go advise against running on the treadmill...in our senior community clubhouse and a hospital health fitness center (where there also a lot of seniors).
    Personally, being outside is uplifting and just nice when flowers are in bloom. Treadmill is basically boring. - 1/13/2013 10:30:19 AM
  • I do both if its below zero I use the treadmill, otherwise I walk outside. But, I also live out in the country and I can only go a couple of ways before I reach my four miles. SO if its raining or looks like its going to storm I go for the tread mill. One thing I do know is the tread mill keeps you at a steady pace where when you are walking outside you may think your walking at the same pace but your not when you start getting tried your body automatically starts to slow done unless your pushing yourself for a specific time. - 1/13/2013 8:58:54 AM
  • Starting running on treadmill first. Don't hate the treadmill but prefer outside running now but like the treadmill for walking. Inc and dec speed and incline for variation. Outside I run on walkway between buildings where I live and run the parking lot because the surface is uneven. When walking downtown where I live, I walk up and down the 45 steps to the train platform for variation. Intend to change my route and will also start to walk/run in the park that is a couple of blocks away. - 11/14/2012 12:00:13 PM
  • Good article. It points out good things about both. I enjoy both based on my mood and the weather personally. My outdoor runs are definitely more challenging however the treadmill allows me to get to lifting weights quicker which is good time wise. - 10/13/2012 10:54:39 AM
  • Great article ....i love both ....i like the controlled aspect of a treadmill and the goal setting (easy to see when you hit a new pr) but who.doesn't lile the wind tje rain the trees and the aliveness of outside - 9/29/2012 9:18:14 AM
  • I love running outdoors, but have to stick with the treadmill at the moment because it's less impact on my [healed but still bothers me when I run outside] ankle. Outside, I run on a bike path but it's still more jarring to my ankle than the treadmill. That being said, I don't hate the treadmill like a lot of other people do... I don't watch TV or anything while doing it, I just vary my speed & incline and focus on how my body's responding.

    Still, I miss running outdoors. But I get out on my bike almost every day to get my fill of fresh air and scenery! - 7/6/2012 8:53:36 AM
  • so far I find that running both in and outdoors is best, it keeps me from getting bored. When I run in a gym I am also strength training, outdoors my kids are riding their bikes to keep up and we have a blast together. - 4/17/2012 3:23:00 PM
  • Interesting article, and in an ideal world, outdoor running/walking would be preferable to using a treadmill indoors. However, I have severe allergies, so that limits my outdoor time in certain seasons and when it's windy. Ironically, I live in an area with mild winters so cold weather is not a detriment to outdoor workouts.

    Another consideration is pollution - from cars, factories, construction activity. It can be healthier to exercise indoors for some of us.

    Also, I live in a semi-rural area where there are no sidewalks, making running a dangerous activity. The roads have no shoulders and there are many have blind curves. I'd be crazy to run in this environment, because I'm not always visible to the oncoming traffic. Not to mention wild animals like coyotes, skunks, and bears - oh my!

    So, I'll stick to the treamill at the gym - and not feel guilty about it. At least at the gym I have several different types of equipment to choose from to vary my workout - treadmill, elliptical machines, weight machines, bikes, rowers, and free weights - and an indoor pool. So, I get a great workout. - 2/19/2012 10:51:27 AM
  • I understand the pros and cons but for me there's one factor that wasn't mentioned. I never could run very far without getting tired and having to slow down to a walk. Outdoors I can break into a run and if I get tired I can just slow down to whatever pace feels OK. On a treadmill I have to set a pace to start running and if I get tired I can't slow down until I set a lower pace. That means I can challenge myself to run outdoors, but I don't feel safe challenging myself to a run on a treadmill. - 2/3/2012 2:13:33 PM
