London Marathon 2026 Guinness World Record holder opens state-of-the-art Exercise Medicine facility at GenesisCare UK’s specialist cancer centre in Oxford
A new state-of-the-art Exercise Medicine facility at GenesisCare UK’s specialist outpatient cancer care centre in Oxford, has been opened by London Marathon 2026 Guinness World Record holder Jenny Ferris, with centre staff, Clinicians and members of GenesisCare’s Executive team joining the event.
September 2026
Jenny, a breast cancer patient who was treated at GenesisCare’s centre in Bristol, holds the record for the fastest marathon by a woman who has undergone a double mastectomy, completing it in 3 hours and 24 minutes, and breaking the previous record by more than an hour.
Hollie Glendenning, Interim Head of Exercise Medicine at GenesisCare says: “Evidence shows that a tailored Exercise Medicine programme greatly supports patients during cancer treatment and improves multiple different cancer health outcomes including fatigue, health-related quality of life, anxiety, depression, bone health, physical function, and sleep. This new Exercise Medicine facility will play a vital role in helping to improve outcomes for patients with cancer, in the Oxford and surrounding areas.
Roberta Fuller, Centre Leader at GenesisCare in Oxford, continued: “We’re delighted to offer our patients the proven health benefits of Exercise Medicine. Every GenesisCare programme is tailored to each patient’s individual needs, helping them build exercise into their routine. Our aim is to make exercise accessible and inclusive for everyone, regardless of their previous activity levels, and to support lasting lifestyle changes.”
GenesisCare is the UK’s leading cancer care provider, specialising in the treatment of complex cancers and transforming cancer care with advanced diagnostics and treatments. Patients who have received Exercise Medicine at GenesisCare report significant improvements in their physical function and emotional wellbeing as well as reductions in cancer-related fatigue levels.
Jenny Ferris says: “I had run marathons before my breast cancer diagnosis, but during treatment I wondered if I would ever run again. The Exercise Medicine team at GenesisCare in Bristol supported me with one-to-one strength training, helping me maintain my fitness. Since completing treatment, I’ve achieved a world record and personal bests at every distance. I’m delighted that patients in Oxford can now benefit from the same life-changing support.”
