Hundreds of strictly Orthodox Jews have taken up cycling at a track in Manchester, leaving the club overwhelmed and worried for rider safety.
There were queues, a shortage of bikes and toddlers running amok at Boggart Hole Clough club after more than 400 Charedim joined a special cycling session on Wednesday.
Volunteer Sue Blaylock, who runs the Simple Cycling charity, said the influx had been "overwhelming". Usually 60 people attend the event.
She said: "I've got to think of the health and safety of everyone. I don't want it to lead to issues like people becoming racist or nasty to each other."
