Born and raised in the mountains of rural northwest Georgia, Chadd grew up obsessed with becoming a SEAL, but when the Navy discovered a rare but asymptomatic cyst on his heart, he was disqualified from entering BUD/s. Chadd refused to give up, ultimately tracking down a surgeon willing to perform a procedure deemed too risky by every cardiologist he previously petitioned. Cyst successfully removed, Chadd went on to realize his SEAL dream, serving over the next decade as a Team Leader on multiple deployments to conflict zones across the world. He became a SEAL instructor. A Master Training Specialist. Chadd even served a stint as President Obama's bodyguard. Along the way, he battled PTSD and traumatic brain injury. Now retired from the military, Chadd has found new life as an elite ultramarathoner — a spiritual quest for self-knowledge and mind-body mastery that has compelled him to tackle some of the world's most insane endurance slogs like The Revenant — a 118-mile footrace across south New Zealand with over 52,000 feet of elevation gain that not one person has ever successfully completed.
