The London Marathon is the largest marathon in the world and since it first began back in 1981, it has become a major sporting and cultural event. It takes place each spring and transforms London into a spectacle!  Around 36,000 runners usually finish the race and the streets of London are packed with thousands of spectators.

BBC One brings you live coverage of this colourful event with commentary and race analysis and some of the personal stories that motivate the many amateur runners.

The London marathon is an iconic event that is full of colour and excitement. Many runners are in fancy dress, there are runners facing personal challenges or disability or similar and the event raises millions for charity each year as runners pound their way round the 26 mile course. There is a wheelchair section of the race so it is a chance to see some of the paralympians in action.  It is easy to forget that as well as the fun and the fancy dress, this is an elite race, which attracts the best athletes in the world and includes Olympic medal holders and world record beaters.
