WESTPORT, Conn.  The triathlete who was hospitalized Sunday at the Sherwood Island Sprint Triathlon died Monday at Norwalk Hospital.

Robert Hartline, 62, of Wallingford, was competing in the event as a member of the Wilton-based Team in Training. According to an obituary provided by Yalesville Funeral Home, Hartline, who died Monday, was a U.S Navy Veteran of the Vietnam War and was an accomplished runner, having competed in the Boston Marathon in the 1980s. He is survived by his wife Patricia, his mother, Dorothy and two sons. The cause of death was not included in the obituary.
