About Capstone

BUILT BY RUNNERS.
FOR RUNNERS.

Capstone was founded by Rob Sembiante, a former Navy Diver who discovered ultrarunning in 2019 as a way to keep chasing the kind of growth he found in military selection programs.

After leaving the service, Rob spent years living out of a van, traveling the country, running trails, and crewing some of the most grueling endurance efforts in the sport, including coast-to-coast FKT attempts across America.

Somewhere on those miles, it became clear: endurance doesn't just test you, it changes you. Rob wanted to build a platform that could deliver that experience to as many people as possible.
