3,063 miles. 52 days. 57 years old…

People drive across the United States all the time, touring the 3,000-plus miles for vacation, relocation, or rite of passage. Every now and then, someone makes the trip on foot, taking a year or more to walk across the great expanse of our country.

Marshall Ulrich ran from San Francisco to New York City in 52.5 days. He was 57 years old and making an attempt to break a world record set by a man half his age.

Completing the mind-bending and body-breaking equivalent of 117 back-to-back marathons, he ran an average of more than 400 miles a week, gained 84,430 feet in elevation, dealt with temperatures ranging from below freezing to the upper 90s, and crossed 12 states.

Ulrich is a versatile, world-class extreme endurance athlete, not only a legendary ultra-runner but also Seven Summits mountaineer and adventure racer. So although his new book, “Running on Empty,” is a memoir mostly about the transcontinental run, it also includes tales and lessons learned from all his athletic pursuits, some painful, some funny, some completely life-changing.
