Last year, Haddenham GP Dr Kaiser Munir ran the London Marathon for charity.
For many people, once is more than enough – running 26 miles and 385 yards in one go can be a very painful experience!
But Dr Munir is made of sterner stuff, and so he is returning to the nation's capital on Sunday 23rd April for a second dose of self-induced suffering as he attempts to better his time in the London Marathon while simultaneously looking to raise funds for a charity that he holds dear: Action for Hearing Loss.
You can read more about why Dr Munir likes to support this charity here.
Most importantly, he is hoping that as many of his patients and friends as possible might feel inclined to help sponsor him for this year's London Marathon.
You can find his JustGiving page here.
We wish him the very best of luck, and hope that he gets round without injury, whatever time it takes!
