Two marathons, three triathlons, a six-day cycle ride and three mountains... those are just some of the 16 challenges Quddous Ahmed is taking on in just over eight months as he attempts to raise £5,000 for charity.
The 26-year-old fitness fanatic, of Blackberry Farm Close, Heston, has set himself the exhausting mission to celebrate the 100th anniversary of the Ahmadiyya Muslim Community in the UK.
Just attempting to read out the list of events he is tackling, which include the Three Peaks Challenge in June, the Berlin Marathon in September and a Glasgow-London bike ride in June, is enough to leave most people short of breath.
But Mr Ahmed, who runs the bicycle courier company Zoom Zoom Couriers, has already completed his fifth London Marathon plus a half marathon and a 10km race since mid-February and said he is looking forward to the challenges ahead.
"I remember completing my first marathon and hearing all the people around me saying 'never again', while I was thinking 'what's next?'" he said.
"I love to push my body to the limit and this is a great way to do that while raising money for some great charities."
The money raised will be split equally between six charities: Humanity First, the Royal British Legion, Cancer Research UK, Leukaemia and Lymphoma Research, British Red Cross and Sightsavers.
When I spoke to Mr Ahmed on what he described as a rest day, having 'only' completed a 5km swim and a 10km run, he said he was driven by a desire to celebrate and give thanks for having the freedom to practise his religion in this country, something so many people across the world do not enjoy.
"In Pakistan and Indonesia members of our community are persecuted and I've spoken to people there for whom even going to pray makes them fear for their lives," he said.
"Here I can practise my religion without fear of persecution, which is why I'm celebrating 100 years of the community in the UK."
