Hundreds of runners gave heart to cardiac patients as they raised money for research and treatment on Sunday.

Almost a thousand runners dressed in red were an impressive sight on Sunday morning as they took part in the annual British Heart Foundation sponsored 5k jog around Knebworth Park.

Event organiser Melanie Blackman said it was the best Knebworth Jog yet.

“We were just short of 1,000 runners but everyone was absolutely brilliant. I would like to send huge thanks to everyone that supported the event this year, from the kind permission of the Lytton Cobbold family and the team at Knebworth Park to our incredible team of BHF Volunteers. But especially to all the fundraising heroes who took part in the event and whose sponsorship will help to save so many lives.”

The charity will be in Stevenage for Health Action Day on May 15 for the Stevenage Splash and Dash - a 450m swim and 10k run, or 350m swim and 5k run for novices.

Money raised from the event will go towards Mending Broken Hearts, the Foundation’s 50th anniversary appeal.
