THE OC star got down on one knee during a romantic trip to Italy last month (OCT05) and told his girlfriend of 18 months that he wanted to sprint down the aisle.
Donovan reveals he knew he had made the right decision to wed entrepreneur Kingsbury when he spotted her cheering him on as he ran in the New York Marathon at the beginning of the month (06NOV05).
He says, "As I approached mile 24, I was in severe agony. My fiancee saw what was happening and literally picked me up and ran with me in her flats (shoes) and silk blouse the final two miles."
Donovan completed the big race and became the 2,646th person to cross the finish line - out of 37,000 runners.
