The Glasgow man said: “Chris was such a great friend and such a good person.

“This is the least I can do to honour him.”

Nathan grew up with Chris, a lifelong Rangers fan, who had been diagnosed with hypertrophic cardiomyopathy at the age of three.

When he was just 22 years old, Chris collapsed and died at work.

In 2024, a mural of Chris’ portrait was unveiled in Glasgow, showing him wearing a Scotland t-shirt with the slogan “Scotland ‘til I died”.

The artwork was part of a British Heart Foundation national campaign designed to highlight the fact that in the UK, 12 young people a week die from sudden cardiac arrests.

This year, Chris’s friend Nathan joined a team of more than 760 BHF runners, took part in the London Marathon on April 27, to help fund the charity’s lifesaving research.

He said: “Taking part in the TCS London Marathon was such a huge challenge and an incredible experience.

“The atmosphere around the course was electric and it was amazing having so many people cheering me on, it made me even more determined to cross the finish line.

“The research funded by the BHF makes such a difference to the over 7.6 million people in the UK living with heart and circulatory diseases.

“I’m proud that I’m doing as much as I can to support their amazing work to help keep families across the UK together for longer.”

Jas Dhanda, events manager at the BHF, added: “It’s fantastic to see Nathan’s courage and determination in helping us fund lifesaving research.

“Without the dedication of our team of BHF runners and the commitment of people like Nathan, we wouldn’t be able to fund research that has already revolutionised treatments and transformed the lives of millions of people in the UK.

“The stories of why our amazing supporters take part never fails to amaze me and it was incredible to see Nathan and 760 others take on such a gruelling challenge to help save and improve lives.”
