David Goggins

David Goggins was married to Aleeza Goggins, a Japanese nurse, and they separated in 2007 after around two years together. He later became engaged to Jennifer Kish, a New York-based executive director.

In Can't Hurt Me, Goggins revealed that he had a child with a previous girlfriend named Pam. He grew up with his mother, Jackie Goggins, his father, Trunnis Goggins, and his brother, Trunnis Jr.

Goggins joined United States Air Force Pararescue training at 19, but he was temporarily removed after being diagnosed with sickle cell trait. He completed his Air Force service as a Tactical Air Control Party member from 1994 to 1999.

After leaving the Air Force, Goggins worked as a pest control fumigator and gained weight, reaching 297 pounds. At 24, a television program about Navy SEAL training motivated him to lose 106 pounds in less than three months so he could meet the entry requirement. He completed Navy SEAL BUD/S training with class 235 in 2001, served with SEAL Team 5, graduated from Army Ranger School in 2004, and deployed to Iraq during his military career.

Goggins began long-distance running in 2005 to raise money for the Special Operations Warrior Foundation after military friends died during a helicopter crash connected with Operation Red Wings. His first ultra challenge was the San Diego One Day, where he ran 101 miles in 18 hours and 56 minutes. His endurance career also included the Badwater Ultramarathon, HURT 100, Ultra-Trail du Mont-Blanc, the IRONMAN World Championship, and the Moab 240.

He finished fifth at the 2006 Badwater-135, third in 2007, and 18th in 2013. In 2016, he won the Infinitus 88K, Music City Ultra 50K, and Strolling Jim 40 Miler. He placed second at the 241-mile Moab 240 in 2020 and completed the Bigfoot 200 in 2025.

Goggins set the Guinness World Record for the most pull-ups completed in 24 hours in 2013, performing 4,030 repetitions in 17 hours. Earlier attempts ended after 2,588 repetitions because of a partially torn forearm muscle and after 3,207 repetitions because of severe burns on his hands.

He popularized the 4x4x48 challenge, which asks participants to run four miles every four hours for 48 hours. His experience at the HURT 100 helped inspire his 40% Rule, the belief that people retain significant physical capacity after their minds begin telling them to stop.

Goggins published Can't Hurt Me: Master Your Mind and Defy the Odds in December 2018. The New York Times best-selling memoir recounts his childhood trauma, weight loss, military service, and endurance competitions while presenting his ideas about mental resilience.

His second book, Never Finished: Unshackle Your Mind and Win the War Within, was published in December 2022. It develops his concept of the "Mental Lab" and presents his approach to continuing through adversity and difficult goals.
