Article continuesChaotic scenes surrounded Sheffield's Half Marathon after organisers cancelled the event due to a lack of water for runners.
There was confusion at the starting line as many of the 4,100 runners decided to carry on running anyway.
South Yorkshire Police said it had initially tried to set up road blocks but later decided it was safer to let them complete the run.
Organisers said they had been "let down" by their water supplier.
Bizarre...totally bizarre.
