If you're looking to test yourself and raise funds for a cause close to your heart - then this challenge is for you! Whether along stunning coastlines or paths through scenic countryside - there's an Ultra Challenge for everyone.

Sponsorship for your Ultra Challenge

To do your challenge for APF you will need to pay a registration fee and commit to raising a minimum amount.

During the booking process, please select 'Full Sponsorship For Charity' and you will find 'Action for Pulmonary Fibrosis' under the 'Health & Medical' section.

Once you have booked your challenge, we will be notified and we'll send you a Fundraising Pack to help get your fundraising started.

Pay for the Ultra Challenge yourself

If you would prefer to pay for your own Ultra Challenge, there is no minimum fundraising target.

Please select 'Own Place Charity Fundraising' and you will find 'Action for Pulmonary Fibrosis' under the 'Health & Medical' section during the registration process.

Once you have booked your challenge, we will be notified and we'll be in touch to support you all the way.
