In this episode of Frogman Friday, Ryan “Birdman” Parrott sits down with Anthony “Staz” Stazicker, British SBS veteran, co-founder of ThruDark, and author of The Hard Road Will Take You Home.

Staz opens up about his 13-year career in the Royal Marines and SBS, the challenges of transition, and how he turned lessons from special operations into building one of the fastest-growing performance brands in the world. He also breaks down Mission Everest—the audacious expedition that saw him and his team summit and return from Mount Everest in under seven days—all while raising money for veteran and children’s charities.

From service to entrepreneurship, fatherhood to endurance, this is an inside look at what it means to “endeavor through adversity.”
