London Marathon organisers have revealed more details about plans to stage a two-day event next year which they say would be an “incredible celebration” that would raise more than £130m for charity and bring in £400m in social and economic benefits.
As the Guardian revealed last month, advanced talks are under way for the one-off event which would allow around 100,000 people to take part, nearly double the number running on Sunday.
