The Science of Longevity in Running: How Some Runners Stay Fast for Decades

Running is often thought of as a young person’s sport, but time and time again, we see athletes defying age, continuing to run and even race well into their 60s, 70s, and beyond. Some runners, like My Best Runs founder Bob Anderson, who started running in February 1962 and is still going strong today, prove that longevity in the sport isn’t just possible—it’s achievable with the right approach.

What allows some runners to maintain speed and endurance over the decades while others slow down? The answer lies in science, training adaptations, mindset, and lifestyle choices. This article explores how runners can stay competitive for life—and perhaps even improve with age.

The Science of Aging and Running Performance

Physiologically, runners experience certain changes as they age:

• VO2 max naturally declines at a rate of about 10% per decade after 40. However, regular training can slow this decline significantly.

• Muscle fibers shrink, and fast-twitch fibers deteriorate faster than slow-twitch fibers, impacting speed and power. Strength training and sprint workouts can help counteract this.

• Tendons lose elasticity, and cartilage wear increases, making injury prevention crucial.

• The body takes longer to recover from hard workouts, making rest, nutrition, and cross-training essential for long-term success.

The good news is that lifelong runners often have stronger hearts, denser bones, and slower biological aging than non-runners. Regular endurance training can reduce the risk of cardiovascular disease, osteoporosis, and cognitive decline.

Training Smart: Adapting Workouts for Longevity

Many runners burn out or get injured because they don’t adjust their training as they age. Here’s how to train smart for decades.

Maintain Speed with Strides and Intervals

Fast-twitch muscle fibers decline faster than slow-twitch fibers, but incorporating short sprints, strides, and intervals helps retain speed. Even just six to eight 100-meter strides at the end of easy runs can keep the neuromuscular system sharp.

Prioritize Strength Training

Strength training two to three times per week can help counteract muscle loss, improve bone density, and prevent injuries. Key exercises include squats, lunges, core work, and hip mobility drills.

Adjust Recovery

Younger runners recover quickly, but for those over 50, rest and active recovery days become more important. Running every day might not be sustainable, but alternating hard workouts with cross-training, such as cycling, swimming, or hiking, can help maintain fitness without overuse injuries.

Keep Mileage Consistent

Aging runners who maintain a consistent but moderate mileage base tend to perform better long-term than those who dramatically reduce or increase mileage. The key is staying active year-round and avoiding long breaks that lead to muscle loss and decreased aerobic capacity.

Nutrition and Recovery: Fueling for the Long Run

Proper nutrition plays a major role in running longevity.

Focus on Anti-Inflammatory Foods

Chronic inflammation contributes to aging and joint pain. Long-term runners benefit from foods rich in omega-3s (salmon, walnuts), antioxidants (berries, leafy greens), and lean proteins (chicken, beans).

Stay Hydrated and Maintain Electrolyte Balance

As we age, our sense of thirst declines, so staying hydrated becomes more critical. Older runners are also more prone to electrolyte imbalances, making magnesium, sodium, and potassium intake vital.

Increase Protein Intake

After 50, the body needs more protein to maintain muscle mass. Aim for 1.2–1.6 grams of protein per kilogram of body weight daily, focusing on high-quality sources like eggs, lean meats, Greek yogurt, and plant-based proteins.

Mental Toughness and Staying Motivated

Longevity in running isn’t just about the body—it’s also about the mind. Many lifelong runners stay motivated by setting new goals, training with a group, and embracing the aging process rather than resisting it.

Bob Anderson, founder of My Best Runs, started running in February 1962 and continues to train and race today. His ability to sustain a high level of performance comes down to consistent training, smart adaptations, and a passion for the sport. His 6:59 per mile pace for 350 miles of racing (50 races totally 350.8 miles over one year) at age 64 is proof that age is just a number when you train right.  More recently he ran 49:48 for 10k at age 76. 

The Role of Cross-Training and Injury Prevention

Even the most dedicated runners face injuries. The key to longevity is knowing when to rest and when to cross-train.

Some of the best cross-training options for runners over 50 include cycling, swimming, pickleball, hiking, and yoga. Incorporating at least one non-running workout per week reduces injury risk and keeps running sustainable for the long haul.

Gene Dykes and Rosa Mota: Icons of Running Longevity

Bob Anderson is not alone in proving that age is just a number. Gene Dykes, one of the most remarkable masters runners in history, has shattered records in his 70s. At age 70, he famously ran a 2:54:23 marathon. 

His secret? A high-mileage approach combined with interval training and a love for the sport that keeps him motivated year after year.

On the women's side, Rosa Mota, the legendary Portuguese marathoner and 1988 Olympic gold medalist, continues to inspire runners worldwide. Even in her 60s, she remains an active ambassador for the sport, showing that passion, consistency, and smart training allow runners to stay competitive for life.

In December 2024, at age 66, Rosa Mota set a new W65 10K world record by completing the San Silvestre Vallecana race in 38:23.

Both Dykes and Mota exemplify the idea that the body can continue to perform at a high level if treated right. Their stories, along with those of runners like Bob Anderson, prove that longevity in running is not just about genetics-it's about persistence, training adaptations, and maintaining the joy of ring.

Final Thoughts: Running for Life

Longevity in running isn’t about fighting age—it’s about embracing the journey, adapting intelligently, and staying passionate. The best runners understand that while paces may slow, the love of the sport grows deeper with time.

Whether you’ve been running since February 1962 like Bob Anderson or are just starting in your 50s or 60s, consistency, smart training, and joy in the process are the real secrets to running for life.
