50 Marathons in 50 States in 50 Days

In 2006, Dean Karnazes took on an amazing challenge called "Endurance 50." He aimed to run 50 marathons in 50 different states on 50 days in a row.

He started with the Lewis and Clark Marathon in St. Louis on September 17, 2006. He finished with the New York City Marathon on November 5. Only eight of these 50 runs were actual marathon races. On the other days, Dean ran the official marathon course in each state. He had help from race organizers and staff to make sure it was an official run. For example, he ran the official course of the Boston Marathon, but not on the day of the big race.

Dean successfully completed this huge goal. He finished the final marathon, the NYC Marathon, in 3 hours and 30 seconds. A film called UltraMarathon Man: 50 Marathons, 50 States, 50 Days was made about this incredible journey.

Other Activities

In 1995, Dean Karnazes started a company called Energy Well Natural Foods in San Francisco. It is now called Good Health Natural Foods, and he is still its president. Dean also writes a regular column for Men's Health magazine.

On the TV show Stan Lee's Superhumans, it was suggested that Dean's body is very good at handling lactic acid. Lactic acid can make your muscles tired during exercise. Dean believes his endurance comes from his body's ability to clear lactate from his blood and turn it into energy. One of his training tips is to eat sardines for protein!
