Cherie Gruenfeld, 81, an Ironman Hall of Famer, completed her first marathon at the age of 42 and retired from competitive racing at 78 with 14 world titles. Yet, she continues to participate in half-Ironmans and long-distance races. Similarly, Rose Marie Savage, 72, began running at 53 and has since completed over 100 races, including six full marathons. Meanwhile, Mildred Baker, 79, recently finished her first half-marathon, marking her 24th race with the New York Road Runners (NYRR). These stories challenge the pervasive belief that running inevitably leads to knee damage.
Running has long been associated with knee injuries, but experts argue that this reputation is undeserved. “I wish I knew why everyone seems to think that running is bad for your knees – it’s a dated notion,” says Dr. Abigail Campbell, an orthopedic sports surgeon at NYU Langone. Research supports her view, indicating that weight-bearing exercises like running can actually improve joint health.
Understanding the Origins of the Myth
The belief that running harms the knees may stem from older studies. A 1995 review suggested that one-third of serious runners sustain injuries annually, with the knee being a common site. Furthermore, a 1996 study in Arthritis & Rheumatology found higher rates of osteoarthritis in retired female athletes compared to non-athletes. Such findings have contributed to the myth that running is detrimental to knee health.
However, Dr. Campbell notes that outdated medical advice has also played a role. Many older patients report being advised against running to protect their knees. This advice persists despite evidence to the contrary, perpetuating the myth that running causes wear and tear leading to arthritis.
The Science Behind Running and Knee Health
Contrary to popular belief, the human body requires weight-bearing exercise. “Bone and cartilage are living tissues that respond to weight-bearing compression,” Dr. Campbell explains. Without such exercise, bone density decreases, and cartilage weakens over time, making impact exercises like running essential for maintaining joint health.
Recent studies further debunk the myth that running leads to arthritis. A 2024 study in Sports Health involving 3,804 marathon runners found no link between running history and arthritis risk. Instead, factors like age, BMI, and previous injuries were significant risk factors. A 2023 review in the Orthopaedic Journal of Sports Medicine also found that running might protect against generalized knee pain.
Practical Advice for Runners of All Ages
Start Slow and Steady
For those new to running, starting gradually is crucial. “I sometimes see people rush and have a lofty goal, like wanting to run a marathon, but it’s important to have small milestones,” advises Lisa Mitro, a physical therapist and run coach. Both Baker and Savage began their journeys with walking before transitioning to running, emphasizing the importance of pacing oneself.
Consider a DEXA Scan
A DEXA scan can assess bone density and help identify risks for fractures, particularly for older runners. Dr. Campbell suggests that those diagnosed with osteopenia or osteoporosis should approach running cautiously, possibly starting with lower-impact activities.
Follow a Training Plan
Setting realistic goals and following a structured training plan can prevent injuries and improve performance. Gruenfeld emphasizes the value of a coach to tailor a plan that considers individual experiences and goals.
Maintain Good Form
Proper running form is essential to avoid knee discomfort. Mitro advises focusing on a relaxed arm swing and ensuring the foot strikes beneath the knee. Visualizing a professional runner can help maintain good form during runs.
Cross-Train for Balance
Incorporating various exercises like swimming, cycling, and strength training can enhance overall fitness and knee mobility. Dr. Campbell and Mitro both advocate for strength training to build stability and protect the knees during impact activities.
Modify Runs as Needed
Adapting running routines to accommodate personal limitations is crucial. Savage, for example, adjusted her training after a knee injury, focusing on shorter races. Recognizing the difference between pain and discomfort can also guide necessary modifications.
The Path Forward: Embracing Running at Any Age
Despite the myths, running can be a lifelong pursuit with numerous health benefits. Dr. Campbell emphasizes that staying active is vital for managing arthritis and preventing immobility-related issues. As the stories of Gruenfeld, Savage, and Baker illustrate, age should not be a barrier to enjoying the rewards of running.
Ultimately, consulting with healthcare professionals and tailoring a running plan to individual needs can enable people of all ages to run safely and enjoyably. With the right approach, running can be a sustainable and enriching activity well into the later years of life.
