Deputy Prime Minister Nick Clegg has called for a "full explanation" into the "farcical" events of the Sheffield half-marathon.
The event was cancelled at the least minute due to water supply issues, but some runners continued anyway, and members of the public supplied water for them.
Mr Clegg said:
"Everyone involved deserves a full explanation of how this farcical situation was allowed to happen. Sheffield is an outstanding city of sport. The extraordinary scenes today shouldn't tarnish that reputation.
"The fact that runners who had carried on regardless were still well supplied with water thanks to spectators, tells you everything you need to know about Sheffield people."
“It is with huge disappointment and regret that we were forced to cancel the 2014 SIG Insulation Sheffield Half Marathon because of a problem with the delivery of water by our suppliers. For health and safety reasons, we were unable to go ahead with race without the required number of water stations throughout the race route. As soon as we learnt of the problem, we did everything in our power to come up with a solution so that the race could go ahead as planned. But, we didn’t want to keep runners and spectators waiting any longer, so we took the decision to call the race off.
– Margaret Lilley chairperson Sheffield Half Marathon
“We would like to express our sincerest apologies to everyone involved in the race who has been affected. But we have made the decision based on the best interest of runners and spectators....At this stage we are unable to provide any further information about whether the race will be re-run in the future. With the majority of the race infrastructure in place, many runners decided to run the route as planned. Those who crossed the finish line with their race number will be timed and we will be providing a list of all finishers and their times.”
