With our Golden Bond places and volunteer runners we'll have 103 people pulling on our bright orange running tops and taking on the 26.2 mile course through the capital.
If you're going down to watch give them a clap as they pass to encourage them on their way or join fellow Meningitis Now supporters at our cheering point at mile 23, just outside the Walrus and Carpenter pub in Monument Street.
Our runners will be among some 37,000 from across the world taking part in the event.
Sarah Langton, event organiser at Meningitis Now, said: "We really appreciate everything all our runners are doing for us and wish them the best of luck. We'll be looking after them once they've finished with a well-deserved sports massage at our post-race reception."
“Their efforts will make such a huge difference to rebuilding futures torn apart by meningitis."
And, who knows, maybe one of our runners will be the one millionth person to cross the finish line of the world’s greatest marathon.
Since the first London Marathon in 1981 when 6,255 runners crossed the finish line, the event has gone from strength to strength.
Organisers will announce the name of the one millionth finisher on Monday 9 May once they’ve had a chance to verify the race results.
