Organisers launch #oneinamillion campaign to celebrate every runner who has completed the 26.2-mile challenge since the first race back in 1981

History will be made on April 24 when a runner crosses the Virgin Money London Marathon finish line to become the millionth finisher of the event.

To celebrate this milestone, organisers have launched a ‘#oneinamillion’ campaign to celebrate every runner who has completed the 26.2-mile challenge since the first race in 1981.

Every runner who has ever finished the event is invited to share a selfie holding their medal or other memorabilia with @LondonMarathon on Twitter, using the hashtag #oneinamillion.

A database of finishers has been created which involved manually inputting 20 years of historical results data. All #oneinamillion runners will be able to search the database by the year (or years) they ran to find their #oneinamillion finisher number(s).

Every finisher in the 35 previous races will be able to order a special #oneinamillion t-shirt printed with their unique #oneinamillion finisher number. The online ordering system for the #oneinamillion t-shirts will go live at virginmoneylondonmarathon.com on February 5.

Dick Beardsley and Inge Simonsen (pictured), joint winners of the first London Marathon in 1981, will have the #oneinamillion number 1 and the men’s winner on April 24 will be #oneinamillion 964334.

Runners in the 2016 Virgin Money London Marathon will be able to order their #oneinamillion t-shirt after this year’s race. All profits from the t-shirts will go to the London Marathon Charitable Trust to fund sports facilities in London and other areas.

“We want to celebrate every member of the London Marathon family,” said event director Hugh Brasher, who is #oneinamillion 23967.

“This is about every single runner who has ever run the event, from club runners to our champions and world record holders, from the charity runners who have raised so many millions for good causes to first-timers.”
