Running long distances puts a lot of stress and strain on your body. You knees and ankles take a tremendous pounding from the hours of training and . . . . if you compare the body type of a marathoner to that of someone who does short burst intervals, you will notice that the marathoner has minimal muscularity versus the short distance runner.
Running intervals of short bursts interspersed with short rest in between will speedup your body’s ability to produce more human growth hormone (HGH), the ‘fitness hormone’, which will improve your strength . . . . and endurance.
Intervals will also allow you to cut down on your workout time since they can be done in a shorter time period while still burning significant calories.
The following article goes into more detail as to why it’s better to run sprints . . . .
Why You Should Run A Mile Instead Of A Marathon
Good news: You can stop feeling guilty about not starting to train for it yet.
As it turns out, you can get some of the same benefits of long-distance running and other types of endurance training without ever passing the five-mile mark.
That’s right. Running fast and hard for just five to 10 minutes a day can add years to your life, just as running for hours can. In fact, people who run for less than an hour a week — so long as they get in their few minutes of daily running — get similar benefits in terms of heart health compared with people who run more than three hours a week.
That finding squares with recent research showing that short bursts of intense exercise can provide some of the same health benefits as long, endurance-style workouts.
Marathoners, Meet Interval Training
One of the most popular forms of the quick workout — and the one that has been studied the most — is interval training. Basically, you work yourself as hard and fast as you can for a few minutes, rest, then do it again. The best part? It typically lasts only between five and 10 minutes total. (There’s even a New York Times workout app based on the idea, called the 7-Minute Workout. More on that here.)
Despite consuming far less time than a marathon training session, an interval workout may actually be healthier in the long run (pun intended), according to some research done in the past decade.
A 2012 study comparing a group of runners who did traditional, continuous runs with a group of runners who did interval training found that both groups achieved nearly the same results. There was one small difference, though. The interval trainers had better peak oxygen uptake, an important measure of endurance.
And a recent study in the journal Diabetologia found that doing walking interval training — an hour of alternating between three minutes of brisk walking and three minutes of stopping — helped people with diabetes control their blood-sugar levels far better than simply walking at the same pace continuously.
Still Not Convinced?
Consider this: Distance running could actually be bad for you.
There’s some evidence to suggest that prolonged, intense exercise — such as the type necessary in the weeks and months before a marathon and in the race itself — can have some unhealthy side effects, from reduced immune function to digestive issues.
Working the body to its maximum, some research shows, can reduce the body’s natural ability to fend off upper-respiratory infections including colds and the flu. Short bouts of activity, on the other hand, improve immune function. Quick workouts appear to not only reduce your chances of getting sick, but to reduce the severity of an illness when you do come down with something.
Up to 71% of long-distance runners also experience abdominal cramping and diarrhea (the latter being so frequent that runners have a term for it: “Runner’s Trots,” aka “runner’s diarrhea“). Many runners (even those without a history of it), experience acid reflux, a condition with effects like heartburn, indigestion, coughing, hoarseness, and asthma during and immediately after a long run.
Here’s what it all comes down to: Whether you stick to a long-distance routine or opt for a quicker, daily exercise plan, it’s important to keep in mind that more is not always better.

P.S. I have been running intervals for years now and have been able to keep my weight within a couple pounds variance during that time. You can also do high intensity training with resistance type exercises by slowing down the reps.
