David Goggins?

David Goggins, born February 17, 1975, is an American ultramarathon runner, ultra-distance cyclist, triathlete, public speaker, and author. He is a retired United States Navy SEAL and former United States Air Force Tactical Air Control Party member who served in the Iraq War. His memoir, Can’t Hurt Me, was released in 2018.

After several of his friends died in Afghanistan in a helicopter crash in 2005 during Operation Red Wings, Goggins began long-distance running with the aim of raising money for the Special Operations Warrior Foundation. The Foundation gives college scholarships and grants to the children of fallen special operations soldiers.[11] Competing in endurance challenges, including the Badwater Ultramarathon three times, has enabled Goggins to raise more than US$2 million for the Special Operations Warrior Foundation.

David Goggins has inspired millions around the world with his acts of heroism and fitness. When we were looking for something out of the ordinary to do this summer, his extreme fitness challenges seemed to be just the ticket – and pairing it with a worthy cause seemed like a no brainer.

The David Goggins 4 x 4 x 48 Challenge consists of running 4 miles (6.43km), every 4 hours, for 48 hours. It is meant to be not only a challenge that taxes the body, but also the mind, as sleep is in short supply with limited breaks between each segment of the run.

It should be alot of fun!
