About 100 visually impaired youngsters aged between four and 16 will compete in the Actionnaires Athletics Day in Sheffield on Saturday.
The event is run by Action for Blind People, and the budding athletes come from all over the north and midlands.
The children will take part in a variety of track and field activities, including long jump, javelin and sprint events, at the day which is being held at the English Institute of Sport in Attercliffe.
Lesley Inganni, operations manager at Action for Blind People, said: “The children are so excited about the event, as many don’t get to participate in sport at all outside of their local Actionnaires clubs.
“It also presents an opportunity for them to sample a range of sports for the first time.”
