Organisers of Sudbury Fun Run will have to wait to find out how much funding they will receive from the town council.
Sudbury Joggers have requested a grant of £2,500 from the authority for the race, but council members want to find out what the money will be spent on.
“This is an organisation and event we would very much like to support, but we want to ascertain exactly what the money is being used for,” said councillor Oliver Forder.
Last year, with the event in jeopardy due to mounting safety costs, the council trained its staff to act as stewards to slash the bill.
Councillors are due to discuss the grant with race organisers soon.
