Jon Devereux

Jon was 28 when he died – just two weeks before he was due to be best man at his brother’s wedding.

Prior to the wedding, six family members ran the 2025 Bristol Half Marathon. It was all part of the run up to the big day, although Jon didn’t need any incentives to get fit. He was a super fit high performing rugby player, ran everyday mixed with gym work, cycling and swimming. With a marathon and several physical events behind him, Jon didn’t need to train for a half marathon.

Leading the family field by some margin Jon reached mile 12 without any symptoms, signs of distress or difficulty. At the time of writing, Jon’s death has been attributed to Sudden Adult Death Syndrome. It appears his heart stopped suddenly and was not able to be restarted, despite the best efforts of medically trained first responders being on hand immediately and a critical care team being in attendance within minutes.

Jon was in the prime of life, playing rugby for a national league 2 side and loving his job with Red Bull Formula 1 Racing with which he toured the world. He was a keen mountaineer, full of energy and supported all those around him to make the most of everyday.

There was nothing to suspect Jon’s heart may have hidden a fatal flaw. His sudden loss has devastated not just his own family but also his wider family of friends as they come to terms with the enormous hole Jon has left behind.

This memorial fund has been set up by the family to help CRY (Cardiac Risk in the Young) raise awareness of young sudden cardiac death, support those affected, support CRY’s screening programme and fund research and pathology.

Claim Gift Aid

Add 25% more to your donation at no cost to you. A Gift Aid declaration allows Cardiac Risk in the Young to claim tax back on eligible donations. It means that for every £1 you donate to Cardiac Risk in the Young we can claim back 25p, at no extra cost to you.

Yes, I would like to claim Gift Aid

By ticking the "Yes" box, I agree I would like Cardiac Risk in the Young to reclaim the tax on all qualifying donations I have made, as well as any future donations, until I notify them otherwise. I understand that if I pay less Income Tax and/or Capital Gains Tax than the amount of Gift Aid claimed on all my donations in that tax year I may be asked to pay any difference. I understand that Cardiac Risk in the Young will reclaim 25p of tax on every £1 that I give.

What is Gift Aid?

Gift Aid does not cost you a penny more, but can add an additional 25p to every £1 you donate. When Cardiac Risk in the Young receives a donation from a UK taxpayer, we're entitled to claim an amount of tax (calculated at the basic rate of income tax in that year) paid on that donation. Once you have given your permission for us to do this on your behalf, there is no need for you to do anything else.

All that is required is that you must be a taxpayer and that would have paid or will pay sufficient Income and/or Capital Gains Tax to cover all the Gift Aid claimed on all your donations in that tax year. Please note that it is your responsibility to pay any difference.

The amount of tax we claim will be 25% of the total value of your donations in that tax year. Furthermore, if you are a higher taxpayer, you are also entitled to claim the difference between the basic rate which we will claim and the amount of tax you have actually paid. For further details on how you can do this, please contact your tax office. If your tax situation changes and your gifts will no longer be eligible for the Gift Aid scheme please contact us and we will amend your record accordingly.

No irrevocable gift, whether outright or life-income in character, will be accepted if under any reasonable set of circumstances the gift would jeopardize the donor’s financial security.

Certain other gifts, real property, personal property, in-kind gifts, non-liquid securities, and contributions whose sources are not transparent or whose use is restricted in some manner, must be reviewed prior to acceptance due to the special obligations raised or liabilities they may pose for Cardiac Risk in the Young.
