Thirty Whittlesey walkers and climbers will attempt to conquer Mount Snowdon to raise £5,000 for the Defibrillators for All charity.

Deborah Slator, of the group, said there are plans to increase the number of defibrillators in the town, which already has 45 outside and 25 others that are commercially owned.

She said: “Jason Osborne who is a keen adventurer suggested we should attempt to climb Mount Snowdon.

“We have spent the summer preparing, some of us losing weight and taking part in running and walking activities to increase our fitness level.

“This is yet another example of how our little town pulls together to achieve great things.

“All walkers have agreed to collect £50 in sponsorship which will help to pay for the heart screening for undiagnosed heart conditions of 100 young people in November.

“For some of the volunteers this is their biggest challenge to date - our youngest walker is eight-years-old.”

Medals will be given out after the climb and the group has a banner to use for photographs at the top of the mountain.

The group will be taking the LLanberis path which is nine miles long.

The walk takes place on August 4.
