A Donegal woman’s quest for new adventures since she gave up smoking will see her going on the world’s fastest zipwire this weekend – and she could reach speeds of 100 mph hundreds of feet above the ground.

Margaret Coyle is heading to north Wales for an adrenaline rush like no other.

This video (of someone else on the run) will give you an idea of what's in store for Margaret.

She will be attached to a zipwire for what the Zip World promoters say is an experience that offers riders “the closest experience a human being can get to skydiving without actually leaping out of a plane.”

In truly breath-taking fashion she will whizz above the Penrhyn Quarry - which until the 1950s was the planet’s largest man-made hole – in what will be her biggest adventure to date.

And she’s also doing it for charity – with sponsorship raised going to Childline.

Margaret, who lives in Letterkenny, really has got a whole new lease of life since going off the fags.

And she is now really living life to the full – and doing things she could not have imagined just a couple of years ago.

“I quit smoking after 25 years and am now smoke-free for 18 months,” she told the Letterkenny Post.

She has climbed Errigal Mountain, Muckish and Cross Mountain (Mt. Krievac) in Medjugorje.

Certainly heights are no problem for Margaret and she has also completed an abseil from the roof of the Hogan Stand in Croke Park as well as skydiving.

Last year she joined Couch to 5k at Letterkenny Community Centre and completed her first 5k in October. Since then, she has joined Run for Fun Letterkenny and runs three times a week. Shehas taken part in several 5k events and also did the Cara Bundoran 10k.

Zip World won international acclaim when it opened Zip World Velocity at Bethesda in March 2013.

The dramatic descent enables those going down the zipwire to reach speeds of over 100 mph – yet you come to gently stop at the end as the last quarter of a mile on Europe’s longest zipwire sees you actually gaining height again to slow you down.

Zip World is expected to attract in the region of 300,000 visitors this year and has been a major boost to tourism in the area. The side also includes a range of other adventure-related attractions including smaller zipwires, a forest roller coaster, bouncing nets and tree-top hoppers and nets as well as underground “bounce below” caverns.

One wonders what’s next for dare devil Margaret after this weekend!

This story appears in this week's edition of the Letterkenny.

Here are some more images of the zipwire and what she can expect.

Good luck Margaret.
