Three sisters are preparing to take on the “UK’s maddest zip wire” in south east Cornwall for Parkinson’s UK next Sunday, April 9.

Gilly Argyle, 65, from Frome, was diagnosed with Parkinson’s 16 years ago. This will be her second challenge for the charity as last year she abseiled the Cranmore Tower in Somerset.

Her efforts have inspired her two sisters, Daphne Lockwood, 66, from Truro, and Rosemary Masters, 69, who lives in Paris, to join her for her latest adventure.

Daphne and Rosemary explained: “We were really impressed as we watched Gilly taking on her abseil so this year we decided to be slightly more supportive, go for it and join her to raise funds for Parkinson’s UK. There may have been a bit of a guilt trip from Gilly too.

“In the UK, one person in every 500 has Parkinson's and everyone’s experience is different but we, like many families have seen how the condition impacts on a person’s life, though clearly, it doesn’t necessarily stop them being amazing people doing amazing things. We hope our small contribution will support the charity in raising awareness, improving care, treatments and to ultimately find a cure.”

The sisters will travel 490m along the zip wire at Adrenalin Quarry near Liskeard, will be 50m in the air and reach speeds of 40mph.

They are hoping to raise £1,000 in sponsorship. To support them go to justgiving.com/fundraising/DaphneLockwood.

The charity still has limited spaces available for the zipwire. Entry fee is just £10 and Parkinson’s UK asks fundraisers to raise at least £50 in sponsorship. Everyone who signs up will receive a free fundraising pack, sponsorship forms, a Parkinson's UK T-shirt and advice and support with fundraising.

Melissa Rimmell, regional fundraiser for Parkinson’s UK in the South West, said: “I’d like to thank Gilly, Daphne and Rosemary for signing up to the zipwire challenge and I hope they really enjoy the experience.

“Gilly is a great example that life doesn’t have to stop with a Parkinson’s diagnosis, and the team’s fundraising will help us to continue our work to support everyone affected by the condition, and to find better treatments and ultimately a cure. I hope people feel inspired by their story to join us for a fun day out.”
