Part 1

Fifty-nine thousand charity runners take to the streets of the capital for the 46th London Marathon, which aims to set a new world record for the most participants in a marathon. They follow the fastest elite men, women and wheelchair racers in the world, running on the same roads and cheered on by the same enthusiastic crowds.

Gabby Logan leads the coverage throughout the day, and she is joined by a team of reporters spread across the 26.2 mile course, including JJ Chalmers, Blue Peter’s Abby Cook, Tim Warwood, and Harry Aikines-Aryeetey. They are on hand to tell the inspirational stories of ordinary people doing extraordinary things and raising millions of pounds for some great causes.
