Marshall Ulrich is an ultrarunner, mountaineer, and
adventure racer who shares his extreme athletic experience and
expertise with others through public speaking engagements,
magazine articles, books, training camps, and expeditions. He’s been
featured in major media, including top news programs, adventure TV
shows, and full-length film documentaries.
Endurance AthleteConsidered an “Endurance King” by Outside magazine, Ulrich’s specialty is competing in extreme
conditions. He has climbed Mount Everest, crossed Death Valley (on foot, in July) a record 22 times,
completed the Seven Summits all on first attempts, finished more than 100 ultramarathons averaging
over 100 miles each, and is one of only three people in the world to have competed in all nine Eco-
Challenge adventure races. He has raced and climbed in Antarctica, Argentina, Australia, Borneo, British
Virgin Islands, Canada, China, Egypt, Eritrea, Fiji, France, Ireland, Italy, Mexico, Morocco, Nepal, New
Zealand, Russia, South Africa, Switzerland, Tanzania, Tibet, Tunisia, and Vietnam.
• At the age of 57, Ulrich broke two transcontinental speed records when he ran 3,063.2 miles in
52.5 days from San Francisco to New York.
• He holds the record for completing the Badwater 146 (a longer precursor to the now 135-mile
race) through Death Valley and to the top of Mt. Whitney.
• He’s run the Death Valley course more times than anyone else, including a fully unaided solo
crossing and a 586-mile “quad” run.
• He completed the Leadville Trail 100 and Pikes Peak marathon on the same weekend, a feat no
one else has ever achieved.
AuthorIn addition to numerous articles for trade magazines and contributions to other people’s books,
Marshall Ulrich has written a memoir, Running on Empty (Penguin, 2011). It captures the raw and
fascinating intensity of the extraordinary physical and mental effort required to complete his
transcontinental crossing as he attempted, at age 57, to break a record set two decades before by a 28
year old. Equal parts adventure story, personal story, and travelogue, ultimately, the book is about
relationships, good and bad, with friends and family; about America and some of its people, places, and
history, including the history of ultrarunning; and about defying the age barrier.
