What's going on?

37,300 racers will set off from one of three allocated start points in Greenwich before running the 26.2 miles (around 42km) to the finish line on The Mall.

The race will be started off by British astronaut Tim Peake, who will count down from 10 to the start of the race.

Major Peake will also be running the marathon – on a treadmill on the International Space Station, following a virtual reality video of the course complete with digital versions of follow racers.

How can I track my friends’ progress?

A live tracking page will be available on the Virgin Money London Marathon website throughout the day, where you can type in a runner’s details and track their progress.

If you have an iOS device, you can also track runner’s progress via an app which will display an interactive map allowing you to track the progress of specific runners.

The app provides information about medical stops and drink stations along the way, crucially, a list nearby pubs.

Who won?

Kenya's Jemima Sumgong overcame a heavy fall to win her first London Marathon ahead of defending women's champion Tigist Tufa.

Sumgong took a tumble at around 23 miles, apparently tangling feet with Aselefech Mergia in an incident that also saw one of the favourites Mary Keitany fall.

Sumgong, who has been a runner-up in the Boston, Chicago and New York marathons, cracked her head against the floor but ignored her clear discomfort to rejoin the leading pack and eventually pass them.

She finished in an unofficial time of two hours 22 minutes and 58 seconds as Tufa failed to haul her in on the final stretch.

David Weir was again denied a record seventh Virgin Money London Marathon title, as Marcel Hug won a sprint finish in the men's wheelchair race.

Weir finished second in 2014 and 2015 and was edged into third this time, with Switzerland's Hug powering towards the finish line ahead of American Kurt Fearnley.

Hug, who won the race two years ago but suffered a puncture last time around, was clocked at one hour 35 minutes and 19 seconds.

How can I watch it?

BBC1 began coverage of the marathon at 8:30am and will continue until 13:30, when BBC2 coverage will begin.

Reporters along the way will include three-time marathon winner Paula Radcliffe and six-time wheelchair race winner Baroness Tanni Grey-Thompson.
