A charity run organised by the East London Mosque Trust has excluded women and girls aged 13 and over from taking part.
The Muslim Charity Run, which was held in Victoria Park in Tower Hamlets on Sunday, said on its website: “Our inclusive atmosphere ensures that every individual, from the youngest to the oldest, can take part and make a difference.”
It added: “This is open to men, boys of all ages and girls under 12, but everyone is welcome at the park to cheer on the runners.”
The organisers have been contacted by BBC London for comment.
