A fitness fanatic taking on 17 charity challenges in the space of a year, including two marathons, has reached the halfway stage of his gruelling mission.

Quddous Ahmed, of Blackberry Farm Close, Heston, completed the Blackpool Summer 10K on Sunday (July 20), which was the eight leg of his ambitious series.

This weekend the 26-year-old will take part in the Thorpe Triathlon in Surrey, which is the first of four events in the space of just five weeks.

Mr Ahmed has already completed his fifth London Marathon and a Glasgow to London bike ride, among other events - all since February this year.

Among the events still on the to-do list are next weekend's London Triathlon and the Berlin Marathon in late September, with the Bupa Great South Run on October 26 the last leg of his mission.

Quddous Ahmed emerges from the water during the Lidl Bananaman Triathlon at Dorney Lake, Windsor, on July 5, which he completed in 1h16m51s
 

He undertook the endeavour to celebrate the 100th anniversary of the Ahmadiyya Muslim Community in the UK, and hopes to raise £5,000 to split between six charities.

"I'm feeling stronger and fitter than I've felt in my whole life, and I've really enjoyed the events I've done so far," he said.

"I finished third in the triathlon at Dorney Lake, in Eton, which was the first time I'd been on a podium in my life and was a beautiful moment."

It has not all been plain sailing for Mr Ahmed, who runs the bicycle courier company Zoom Zoom Couriers.

He was planning to cycle 600 miles to the annual Ahmadiyya convention in Karlsruhe, Germany, in June, but had to cancel that leg of his journey because he couldn't get his passport sorted in time.

Not one to take it easy, he added two extra triathlons in its place, taking his list of challenges to 17, rather than the 16 he had originally planned.

He also had to pull out of the Three Peaks Challenge to scale the UK's tallest mountains in May, after spraining his ankle during the descent of Ben Nevis.

Although he is halfway through his quest, he remains a long way short of his fundraising target, with £450 so far, including £50 from Feltham & Heston MP Seema Malhotra, who he met at the end of the Glasgow-London bike ride.
