The sporty doc, a GP at the Bentley Practice, took on the endurance dash in memory of his grandparents and patients who died of the illness and also works closely with the Macmillan Survivorship Partnership (MSP).
David said: “The reaction to my entry in the London Marathon has been overwhelming. I’ve had so many kind donations and I’m very happy to have completed the run for such a fantastic cause.
“By the 16th mile I felt my hip starting to hurt, and then by the 18th I felt one of my knees aching under the strain, but the occasion and atmosphere kept me going and I’m just glad that I’ve been able to do my bit to raise money and awareness of such a great charity.”
David starting preparation for the annual run on 1 December and booked himself in for a ‘warm-up’ rowing marathon in Rome just five weeks before the big event in London.
