An 80-year-old grandmother is taking on the fastest zipwire challenge in Europe to raise money for charity.

Former journalist and TV presenter Rhonda Davis from Bushey in Hertfordshire will be taking on the fastest zipwire challenge to fundraise for the hospitals that saved her life and have looked after her for the past six years on Sunday, May 19.

Three years ago she jumped out of an aeroplane at 13,500 feet in a tandem sky dive and last year she abseiled 100 metres down the Spinnaker Tower in Portsmouth.

These challenges raised funds for Royal Brompton and Harefield Hospitals Charity's Trust Research Programme.

Following a double heart by-pass plus a further eight stents, two years later, Ms Davis was jokingly told by her consultant, she "now had a heart as strong as a twenty-five-year-old" - which inspired her to put it to the test with this series of challenges.

This year she will take on the Velocity 2 Zip Wire at Penrhyn Quarry in North Wales, which travels up to 125 mph - the fastest in Europe.

Together with her daredevil cardiologist Dr. Will Wallis of Watford General Hospital, mother of three Sallinder Rai and charity fundraising manager at Royal Brompton and Harefield Hospitals Charity.

The funds raised by these adventurers will go toward the Charity’s pioneering Harefield Transplant Appeal, to raise funds for Organ Care Systems to allow more patients to receive life-saving transplants.
