Follow live coverage of the rescheduled 2020 London Marathon across BBC One, BBC Two, Red Button, BBC iPlayer, BBC Sport website and mobile app.
This year's 40th edition, taking place on Sunday, 4 October because of the coronavirus pandemic, is restricted to elite athletes, who will be in a bio-secure bubble during race week.
For 45,000 non-elite runners from around the world, a '24-hour virtual London Marathon' will also be held so participants can still take part in the day.
Gabby Logan hosts eight hours of live coverage, with commentary from Steve Cram and Andrew Cotter.
Coverage of the elite women's race gets under way on BBC Two at 07:00 BST, with defending champion and world record holder Brigid Kosgei of Kenya hoping to set a new world's best time.
Over on BBC One from 10:00 BST, world record holder Eliud Kipchoge aims for a fifth title, while Mo Farah will help with the pacemaking in the men's race.
In the wheelchair races, which start on BBC Two from 13:00 BST, British Paralympic great David Weir will be aiming for a record ninth win in the men's event, with course record holder Manuela Schar attempting to follow up her 2019 success in the women's race.
BBC Sport's live text commentary page will cover all of the day's events and we want you to get involved across social media.
