Cole Crosby hugs Matt Dibb at the end of Crosby’s successful FKT attempt on the Bay Circuit Trail. Dibb was the previous record-holder and paced Crosby for the final 25 miles. “That was like a storybook ending,” Crosby said. “To share the last marathon with him was really special; it was really the cherry on the top. It was just the perfect way to conclude this whole experiment.” Photo by Chris Wristen/MassUltra
