New sports performance brand, Cramp Killa, has announced a game-changing partnership, pledging to donate £1 from every sale of its anti-cramp performance products to Brain Tumour Research.
Founded by 28-year-old entrepreneur and endurance athlete Jack Dilger, the partnership was inspired by his mother, Michelle Dilger’s diagnosis of a glioblastoma, the most aggressive form of brain cancer, in 2018. Despite being given a devastating prognosis of 12 months, now aged 60, she continues to show remarkable resilience more than seven years later.
Jack said: “Mum’s tumour experience transformed my outlook on life and inspired me to build a brand with a purpose beyond sport. Cramp Killa isn’t just about helping athletes perform at their best. It’s about creating something positive from an incredibly difficult experience. Every order placed means another contribution towards finding a cure for brain tumours.”
The partnership with Brain Tumour Research was also shaped by Jack’s friendship with Archie Goodburn, who has become the brand’s first athlete ambassador after being diagnosed with three oligodendrogliomas brain tumours while pursuing an elite swimming career. The brand has also been endorsed by swimmer Max Litchfield, a three times Olympian and British record holder.
During a recent visit to the Brain Tumour Research Centre of Excellence at the Sutton campus of The Institute of Cancer Research Jack witnessed scientist’s work in the laboratory to get treatments for paediatric brain tumours into trials within the next five years. It’s research such as this which Jack hopes the partnership will help drive: “The more successful the brand becomes, the more we can raise for research. That’s what drives me every single day.”

Our CEO Dan Knowles said: “Our scientists are working day in, day out to unravel the underlying biology of these dreadful tumours and hopefully uncover new ways to attack them. This invaluable partnership with Cramp Killa will help to fuel new discoveries and pave the way to smarter, kinder treatments for everyone. Partnerships like this are incredibly important because they not only raise vital funds for research but also help shine a light on the devastating impact brain tumours have on families across the UK. Jack’s story is a powerful reminder of why greater investment in research is urgently needed. We are hugely grateful to Cramp Killa for supporting our mission to find a cure.”
