Karnazes ran 350 miles through northern California without stopping from October 12–15, 2005. He didn't stop to sleep, eat, or—the most astounding feat of all—slow down to enjoy a cool Sonoma Valley chardonnay. He ran for a total of 80 hours and 44 minutes without stopping. His average speed was about 10 miles an hour.
In fact, running such long distances without stopping is very difficult. It can lead to severe injuries or even death if someone doesn't do it often enough to become accustomed to these stresses. The human body was not designed to go for days without sleeping or eating properly.
But what if we allowed our bodies such freedom in times of danger? What if runners were able to fight fires or climb mountains without stopping every few hours? Well, that's exactly what fire departments and search-and-rescue teams are for. They provide protection for people who could not protect themselves.
So, yes, someone has run farther than you thought possible without stopping. In fact, there are people out there who have run hundreds of miles without stopping. But they're not running from something, they're running to something—they're helping others in need.
Daniel Komen of Kenya ran two miles in less than eight minutes in 1997, doubling Bannister's record. He ran it again in February 1998, coming only 0.3 seconds short of his prior time of 7:58.61. He is still the only person who has completed the feat.
When you double a record, it becomes a "official" record. The original record holder gets to choose how they are honored - usually with a banner at the location that the record was set on. In Komen's case, these banners have been placed by organizations around the world that he has helped raise money for, such as the American Cancer Society and the Susan G. Komen Breast Cancer Foundation.
He has also become a role model for those suffering from cancer. Since his record-setting performance, he has raised over $1 million for cancer charities.
In addition to his record-setting performances, Komen has also come forward about his battle with cancer. In 2004, he told the BBC that he had been diagnosed with prostate cancer three years earlier. In 2007, he told the New York Times that he had returned to running (after taking some time off due to injuries) because it provided him with a way to help others fight cancer.
Komen has also created a foundation in his name to help find a cure for cancer.
What is the furthest distance someone has ran in a 24-hour period? Yiannis Kouros, a Greek runner, holds the world record for distance running: 188 miles (303 kilometers). Kouros holds all men's competition world records for distances ranging from more than 100 miles (161 kilometers) to 1,600 miles (2,575 kilometers) performed in one to ten days. His longest race was an ultra-endurance foot race known as the Athens International Marathon, which he completed in Ephyai, Greece, on August 5, 2004.
Kouros began running when he was 12 years old and became one of Greece's best runners during his career as a pro athlete. He ran in about 30 races each year with the major event being the Athens International Marathon. This race consists of two parts: a full marathon over the course of 26 miles (42 kilometers) and a half marathon over the course of 13 miles (21 kilometers).
In addition to holding several European records, Kouros also holds the American record for the most amount of money spent on sports activities in one year. In 2003 he earned $150,000 by competing in various races throughout the world. His biggest win came in April when he took first place at the Athens International Marathon with a time of 1:46:44.
Since his retirement from professional racing, Kouros has continued to run but under his own banner team.
Shiso Kanakuri (Japan) finished a marathon in Stockholm, Sweden, that he had begun in 1912. His marathon time of 54 years, 246 days, 5 hours, 32 minutes, 20.3 seconds is the longest ever recorded. The oldest person to have run a marathon was Jeanne Louise Calment who died at age 122 in Arles, France.
Kanakuri's record was not recognized by some authorities because it was measured using the Swedish system of measuring times which was based on the American system at that time. However, Kanakuri did not change his behavior or training program in any way when switching measurement systems. He also ran another Stockholm Marathon two months later with the new American-based timing system and again set a new record: 55 years, 266 days.
The current world record holder is Eliud Kipchoge from Kenya who in February 2017 broke his own world record by nearly four minutes when he completed the Berlin Marathon in 2:17:00.
However, there are questions about whether or not this record will stand since many experts believe it was achieved using performance-enhancing drugs. In April 2018, the IAAF announced that Kipchoge's record had been disqualified due to "suspicious activities" during an out-of-competition drug test performed before the race. Kipchoge has yet to comment on these allegations.
So the ordinary person—or even an above-average person—will run between 15 and 22 miles before they are physically unable to continue or are "too exhausted to run." This is based on average people who do not exercise excessively nor underachieve. Scientists estimate that the maximum distance that the average person can run in a day is about 12 miles.
The human body was not designed for walking. Modern humans are capable of walking approximately 2 miles per hour for 30 minutes without significant interruption before becoming fatigued. A man weighing around 150 pounds would need to walk approximately 0.5 miles per hour for five hours continuously without rest. A woman weighing around 100 pounds would need to walk approximately 1 mile per hour for three hours continuously without rest.
The average person can run for several hours without sleep, but they will become more tired over time and will require more sleep as they age. Those who try to run while sleep deprived or not properly rested risk injury or death.
Maximum running speeds vary significantly among individuals; however, most experts agree that the maximum speed a healthy male human can run is about 4 miles per hour. The maximum speed a healthy female human can run is slightly less than 3 miles per hour.
The average life span is 79 years old for males and 85 years old for females.
