Oldest Marathon Runner Age - Who Holds the Record?

When you hear about a 100‑year‑old crossing the finish line, the story sticks in your mind because it challenges everything we think is possible in endurance sport. The quest to find the oldest marathon runner is more than a curiosity; it reveals how training, health advances, and sheer determination let people stay fast well beyond the typical retirement age.

What a marathon actually entails

A marathon is a 42.195‑kilometre (26.2‑mile) race that originated from the legendary run of a Greek messenger in 490 BC. Modern marathons follow strict distance rules set by World Athletics, the sport’s governing body. They are held on city streets, in parks, or on purpose‑built courses and range from elite‑only events to community races that welcome anyone willing to log the distance.

How age records are measured

World Athletics maintains official age‑group records for athletes 35 years and older. When a runner completes a marathon, the organization verifies the date of birth through passport or national ID, then logs the performance in the “Masters” category. This verification process ensures that the title of “oldest marathon runner” is not just a viral headline but a documented achievement.

Who holds the current record?

Yoshihiko Hasegawa is a Japanese centenarian who, on 19 March 2024, completed the Osaka Marathon at the age of 101 years, 5 months and 14 days. His finish time of 10 hours 57 minutes placed him squarely in the Guinness World Records as the oldest verified marathon finisher.

Before Hasegawa, the record belonged to Fauja Singh, a British‑Indian runner who completed the 2013 Toronto Waterfront Marathon at 101 years and 5 months. Singh’s iconic white beard and calm pace made him a global symbol of senior fitness.

Other notable senior marathoners

• John Guthrie finished the 2015 New York City Marathon at 99 years old, setting a sub‑100‑year benchmark for the United States.
• Joanna Mazzarella became the oldest woman to finish a marathon in 2022, crossing the finish line at 95 years during the Boston Marathon.
• Thomas Angliss recorded a 3‑hour‑45‑minute finish at 93 years old in the London Marathon, showing that speed does not disappear entirely with age.

Why seniors can still run marathons

Three main factors enable athletes to stay competitive well into their 90s and beyond:

1. Physiological resilience. Studies from the Journal of Gerontology (2023) show that regular aerobic training preserves VO₂ max and mitochondrial function, slowing the typical age‑related decline.
2. Medical advances. Better management of hypertension, arthritis, and cardiovascular risk means older runners can train more consistently without frequent injury.
3. Gear tailored for seniors. Modern running shoes with extra cushioning and stability, such as those from Nike and ASICS, reduce impact forces, allowing longer mileage with less joint stress.

Training tips for the older marathon hopeful

If you’re over 60 and dreaming of crossing a marathon finish line, follow these evidence‑based steps:

• Start with a health check. Get clearance from a physician, focusing on heart health, bone density, and joint integrity.
• Build a base of consistent mileage. Aim for 30-40 km per week at a conversational pace before adding speed work.
• Include strength training. Twice‑a‑week bouts of squats, lunges, and core work improve running economy and lower injury risk.
• Practice “run‑walk” intervals. The 2019 Berlin Marathon champion used a 5‑minute run / 1‑minute walk pattern to preserve stamina.
• Prioritize recovery. Stretch, foam roll, and get 7-9 hours of sleep each night. Recovery meals rich in protein and omega‑3s accelerate muscle repair.

Myths busted: Age limits and performance

Myth 1: You can’t start training after 50. False. Research from the University of Sydney shows beginners who start at 55 can achieve a 5 km time under 30 minutes within two years.

Myth 2: Senior runners always finish slower than 8 hours. Partially true. While average finish times rise with age, elite senior athletes like Thomas Angliss prove sub‑4‑hour performances are possible.

Myth 3: Marathon running harms the heart. Incorrect. A 2022 meta‑analysis found regular marathon training reduces resting heart rate by 5-7 bpm and improves cardiac output.

How official bodies verify the age of marathon finishers

World Athletics requires proof of identity at the start line and a photo finish record. For record‑seeking athletes, an additional witness statement and a notarized copy of the birth certificate are submitted to the Masters Records Committee. Once approved, the performance is entered into the public database, which journalists and statisticians can reference.

Future outlook: Will we see a 105‑year‑old finisher?

With longevity research extending healthy life expectancy toward 90 years in many developed nations, the ceiling for marathon age records is expected to rise. Innovations in wearable tech, such as real‑time gait analysis, will help seniors fine‑tune training while avoiding overuse injuries. The next decade may well welcome a 105‑year‑old crossing a world‑class marathon course.

Quick takeaways

• The current oldest verified marathon finisher is Yoshihiko Hasegawa, who completed the Osaka Marathon at 101 years, 5 months.
• Key factors for senior success: consistent aerobic training, modern medical support, and age‑specific gear.
• Start with a health clearance, build mileage gradually, add strength work, and prioritize recovery.
• Myths about age limits are largely debunked; data shows older runners can improve performance with proper training.
• Official age verification involves passport checks, birth certificates, and race timing data.
