Daniel Jackson and his dad George Jackson AN Oldbury man is preparing to tackle a gruelling charity fitness challenge inspired by his dad who suffered a life-changing stroke. Daniel Jackson, of Swan Crescent, will be undertaking a punishing 16-mile trek up and down the Pen Y Fan mountain – the highest peak in south Wales – complete with 35lbs of food and water strapped to his back on Sunday June 27. Dubbed the SAS Fan Dance Challenge, the notorious test of endurance must be completed in under four-and-a-quarter hours. Former Leasowes High pupil Daniel, aged 41, will be joined by friends Craig Hodgetts and Alan Harris, from Halesowen.
