My Reason to Run

Gabby Logan is at the Running Show to look ahead to the 46th London Marathon, which promises to set a new world record for the most participants in a marathon. She meets some of the inspirational charity runners, all with their own unique reasons to run this year, including those who are lacing up their trainers to raise millions of pounds for brilliant causes. And she is joined by former marathon world record holder Paula Radcliffe to look ahead to some of the most competitive elite races ever run.
