The chief executive of Cure Leukaemia is set to run 224 miles with the aim of raising £100,000.
James McLaughlin will complete runs in 16 locations, including Oxford on September 17, as part of Run The Nations 2024.
For his 12 miles in the city, he will be joined by patients, families, friends, and clinicians from the Haematology and Cancer Centre at Churchill Hospital, where Cure Leukaemia funds research nurses as part of the national Trials Acceleration Programme.
The run will take place throughout Blood Cancer Awareness Month, September, and will be 80 per cent longer than last year's run.
The £100,000 target is enough to fund the equivalent of two Cure Leukaemia research nurses.
Mr McLaughlin, a keen runner, hopes to highlight the importance of funding of specialist research nurses to enable blood cancer patients to access therapies.
He said: "I am honoured to take on this challenge and run for the countless individuals affected by blood cancer.
"Every step of this journey is dedicated to the patients, families, and medical professionals who inspire us daily.
"Through Run The Nations we hope to not only raise vital funds but also amplify the voices of those who need our support the most."
At the launch of Run The Nations at the Centre of Clinical Haematology in Birmingham, professor Charlie Craddock added: "The mere statement that James is running to centres across the UK underlines the importance of collegiality and the importance of working together to improve patient outcomes."
Starting from the University Hospital of Wales, in Cardiff, Mr McLaughlin will complete runs at 16 key locations, engaging with communities, patients, clinicians and supporters at each hospital.
He aims to run an average of 14 miles in each location to signify every 14 minutes, someone in the UK is diagnosed with a form of blood cancer.
He will also complete two isolation legs, one in London and the other from Leeds to Sheffield, to reflect patients who endure the mental and physical struggles of treatment in isolation.
Speaking on his time in isolation during his treatment, Geoff Thomas said: "Isolation days often stretch longer than a day for blood cancer patients.
"It’s tough, it’s a mental strain and you look forward to the nurses and doctors coming in because that’s your day and you’re ticking off every minute."
Run The Nations 2024 will finish with an event in Manchester, celebrating the collective effort to combat blood cancer with the aim of hitting the £100,000 fundraising target.
