Ana Nobre, 40, of Dukes Road, will take part in the gruelling 10k event, which includes a 10ft wall and scramble nets, at Benington in Hertfordshire on March 29. She is raising money for the Roy Castle Lung Cancer Foundation to support her mum, Elviva Bernardino, pictured, who has the disease. Anas mum, who is 68 and has never smoked, was diagnosed with terminal lung cancer in February last year. Ana told The Hunts Post: We just take one day at a time, but I want to do something to support my mum who has always worked so hard and supported her family without complaining about anything. My mum has always been there for me and I cant imagine life without her so raising money for the lung cancer charity is actually good therapy for me as I feel I am doing something positive. Ana is training for the One True Grit event at The Unit Fitness Studio in Godmanchester and has already raised £250 from a cake stall and a car wash. She also hosted a coffee morning at McNish Court in Eaton Socon, the sheltered housing complex where her mum lives, on Monday and Café Nero in St Neots is holding a fundraising day on March 28 and will be collecting money. INFORMATION: Ana is collecting raffle prizes and hopes people will sponsor her to take part in the One True Grit challenge. If you would like to help, go to www.justgiving.com\/Ana-Nobre. The Lung Cancer Fund was launched in 1990 and changed its name to the Roy Castle Lung Cancer Foundation in 1993 when entertainer Roy Castle revealed he had the disease and raised millions of pounds for the charity in the last year of his life.
