Amy Townsend, from Stratford-upon-Avon, did get to run, and she raised over £1,000 with friends Emma Davies, Charlotte Ponder, and Katie May.

Taking part in her first ever half-marathon she said: “Me and the girls ran the whole race together, they helped me to complete it.”

“It was a big achievement,” she added. “I didn’t experience any problems but there were big queues for parking.”

As well as queues beforehand, not helped by roadworks near the castle, after the run, it took some people over two hours to get out of the “quagmire” of a car park.

Clare Pearce, Regional Head of Events at the British Heart Foundation said:“To the runners who came to the event but were unable to take part, we apologise.”

“Heavy traffic at the entrance to Warwick Castle meant that some people had to be turned away, as the deadline for closing the roads used in the race, as agreed with the Police and Highways Authority, had passed.

“This is the first year we’ve run this event, and we’ve been given plenty of food for thought for next year’s race.

“We wholeheartedly appreciate the amazing lengths you have all gone to: training, fundraising and running for heart patients and heart disease research across the UK.”

She confirmed that plans are already underway for next year’s race.
