Previous studies have demonstrated evidence of temporary heart injury in marathon runners. Fortunately, all of the cardiac abnormalities disappeared within a week after completing a race. Furthermore, these studies followed young marathon runners (between ages 18 and 40). Read on to find out if marathon running is safe for older adults.
Is marathon running safe for older adults?
In a recent study, researchers from the University of Manitoba used blood tests, echocardiography (ultrasound of the heart), CT, and MRI scans to test healthy runners over the age of 50 who participated in the 2010 and 2011 Manitoba Full Marathons.
This study, which was published in the Journal of Cardiovascular MRI, was the first study to use cardiac computed tomography (CT) in marathoners over the age of 50 to detect the presence of heart damage and blockage.
The researchers found similar temporary heart damage as those found in runners between 18 and 40 years of age: transient increase in blood markers and temporary swelling and weakness of the right side of the heart immediately following the 26.2 mile run. However, just like the studies on younger marathon runners, all of the changes in the heart returned to normal one week after the marathon.
The final conclusion? Marathon running is safe for older adults and the repeated stress on the heart from running 26.2 miles does not seem to result in any permanent injury to the heart in people over 50.

Dr Jeff went from a 270 pound FATMAN, to a 205 pound 8 time IRONMAN FINISHER.
Like many other people, Dr. Jeff was a high school and college athlete and never had to think about being over weight, but somehow life caught up to him, and over the years Dr. Jeff began to gradually gain weight. Well, that gradual weight gain ended up creating a six foot two, thirty two year old weighing close to 270 POUNDS!
Not only was he very overweight, he also had high blood pressure, high cholesterol, was depressed about the way he looked, and was on a crash course to developing countless diseases related to obesity. After years of struggling with fad diets, gimmick supplements, and ineffective exercise programs, Dr. Jeff had enough.
He began studying exercise physiology, nutrition, and various training methods and began competing in mini triathlons. One thing lead to another before he knew it, Dr. Jeff lost over 70 pounds and finished the Ironman Triathlon, which is a 2.4 mile swim, followed by a 112 mile bike, then followed by a 26.2 mile run all in one day. Dr Jeff was a true Fatman To Ironman!
Dr. Jeff not only found a new body, he found a new life. This weight loss and his personal experience training and competing in endurance sports lead Dr. Jeff to focus his practice on the prevention and treatment of sports related injuries, sports performance and weight loss.
Dr. Jeff now wears two hats, one as a healer helping people with pain and injuries, and one as a weight loss and endurance coach.
