Help fund cutting edge research into new therapies and treatments for cystic fibrosis by taking part in Great Strides™!

Since 2012, the charity has raised over £700,000 tackling the great outdoors with the Great Strides™ walking series.

How your money helps

Money raised through events like Great Strides is  essential to unite people to stop cystic fibrosis. The community will improve care, speak out, support each other and fund vital research towards effective treatment for all. The Cystic Fibrosis Trust won't stop until everyone can live without the limits of cystic fibrosis.

  • £110 could contribute to life-changing research into CF, by providing a day's funding for a PHD student in a research project.
  • £250 could pay for one of our transplant grants, helping ease the huge financial and emotional burden that families on a transplant journey can face.
  • £350 could fund one of our health and wellbeing grants, helping those in financial need to buy essential items and services that will help them life well with CF.


Fundraising page

When you sign up for Great Strides™, you will automatically receive your JustGiving fundraising page so you can start fundraising straight away!

Fundraising is all part of the challenge and there are lots of ideas to help you reach your target. Every pound you raise will help the Cystic Fibrosis Trust unite for a life unlimited for everyone with CF.

14-17 year olds must be accompanied by a parent or guardian throughout the challenge.

We enjoy the challenge of this kind of event and love the CF community coming together - both walkers and supporters. When the walk gets tough, I remind myself that those with cystic fibrosis face daily challenges and that I can get through this one day! Denise, Walley’s Walkers

Do it! You will have a fabulous time, you’ll get fitter and you will really get to know your team mates better! And best of all, you’ll raise lots of money towards the work of the CF Trust. Mandy

I loved the freedom of walking. I loved all the fresh air and really didn’t mind what the weather was like. It’s such an amazing sense of achievement when you finish. Gayle
