Fifteeen campaigners taking turns on an indoor rowing machine in Dronfield came within a whisker of creating a new record.
The challenge was to row more than 347,000 metres non-stop over 24 hours, at the Woodlands fitness centre.
Organiser Richard Campos, from Norton, Sheffield organised the endurance feat where each person rowed for two minutes and then handed over to a team-mate.
The aim was to row an average 500 metres every two minutes. They then had 18 minutes rest between their rowing slots.
Campos said: “We missed the record by 5km. Each and everyone of the team gave of their best and although disappointed they were delighted to have so very nearly overturned a record set by a rowing club in the USA.”
The Sheffield Children’s Hospital and the ARC antenatal charity benefited from their efforts. In August Campos, 62, competed a rowing stint covering the equivalent of one million metres (621 miles.)
