Really sorry to hear this.
Story:
Pennsylvania -- Many area martial artists were numb yesterday as they learned of the death of Robert Massaroni, a champion Tang Soo Do instructor who collapsed and died moments after he finished a 10-mile street run on Sunday.
Massaroni, 29, of Holland, Bucks County, was chief instructor at the Bensalem branch of Nate Gordon's Black Belt Academy, where he was idolized by his "little dragons," the younger students who trailed after him.
He collapsed just after completing a point-to-point run that Runner's World magazine has named one of the fastest 10-mile courses in the nation. The race started at Central High School at 8:30 a.m. and finished at the end of Broad Street in South Philadelphia.
