Energetic Vale of Clwyd athletes have cycled a mammoth 1,000 miles in 24 hours to raise funds for a worthy cause.

Organised by the Denbigh Dogs rugby team, a group of cyclists - both young and young at heart - pedalled around Llyn Brenig for the lengthy challenge in aid of Welsh Hearts.

The intention of the fundraisers, led by Jonathan Casemore, is to help with the purchase of defibrillators in rural areas.

Defibrillators cost in the region of £2,000.

"It's really important to have these defibrillators in rural spots," said Jonathan.

"I came up with the idea for the Brenig challenge with local fireman Trystan Rowlands.

"There were four of us who are coaches with the mini section.

"A couple of lads with the mini section did some laps.

"It was a good day.

"It was hard work and it went really well, and the guys at the Brenig were amazing."

Llyn Brenig kindly supplied the use of a cabin, toilets and bikes for the challenge.

Following the event, Jonathan added: "The legs were fine.

"The adrenaline kept us going.

"The team cycled for 24 hours.

"There were six of us who were doing the 24 hours in laps, with breaks in between.

"We also had six super-subs who did laps for us.

"Out of the main riders, we did 100 miles each and the rest was made up by the super-subs.

"I had the idea and I set up the Denbigh veterans O-35s about eight years ago.

"We were trying to bring some of the old guys back and we have done a lot of charity work.

"Last year we did one on Anglesey to pay for a defibrillator at Denbigh Rugby Club."

The group has been raising funds to pay for two defibrillators in Hendrerwydd and Llangynhafal.

"I did a ride with the Goldie in Llangynhafal of 200 miles in three days.

"We raised between £2,000 and £3,000 with that.

"From Saturday, we raised about £400, but we have got £300-£400 elsewhere.

"We are at Denbigh Rugby Club in a few weeks' time when RGC play there and we are having a bucket collection.

"I would like to thank Llyn Brenig for their help and the hiring of bikes.

"It was just a tremendous effort by everybody and it's nice to see the older part of the club coming together with the younger part of the club.

"Some people hadn't ridden in 15 years and they all did a lap.

"I think we are going to continue raising money for Welsh Hearts.
