Boston Marathon finale for inspirational Team Hoyt duo

As the Boston Marathon approaches, the BBC's Lee James meets Rick Hoyt and his father Dick as the duo - known as Team Hoyt - prepare to tackle the race for the final time together.

Dick, 74, has pushed his son, who has cerebral palsy, around the 26.2-mile course more than 30 times and Rick, 52, says Monday's Massachusetts race is "the one event that I look forward to all year long".

Last year the Boston Marathon was abandoned after two bombs exploded near the finish line, killing three people and injuring 264.
