On the day of the race, Codner wrote Andrew's name on the top of his running shoes to keep him motivated. Friends and family were stationed outside the hospital to cheer him on, in a course that took 5 hours and 35 laps to complete. His son was even able to run with him across the finish line and award him a medal.

"To see him running and doing that last lap with me was just incredible," Codner said.
