A young man has completed a challenge in which he ran 15 marathons throughout 2015.

Adam Sultan, 26, from Hogarth Court, in Bushey, took on the challenge after his father died of lung cancer in October 2014.

Although his father was treated with chemotherapy he died quickly and during his illness Mr Sultan’s family was supported by a Macmillan nurse.

After his father’s death Mr Sultan decided to fundraise for Macmillan and took on the challenge to complete 15 marathons in 2015.

He said: “My dad had cancer in 2014 and he passed away towards the end of the year.

“I wanted to do something significant for Macmillan to try and raise as much money as possible.

“Currently I have raised £4,000 but there is more donations to come.

“I ran 15 marathons because of the year and it had a nice ring to it, 15 and 15, and I was really lucky I didn’t get an injury. I had a really intense part where I ran four marathons in four weeks in June.”

Mr Sultan signed up for challenges all over the world and competed in the Midnight Sun Marathon in the Artic Circle in Norway and the Athens marathon.

 “It was amazing to run the Athens Marathon as my last one where you start in a small town called Marathon and run to the city centre,” he said.

The concept of a marathon comes from the legend of Pheidippides, a Greek soldier, who ran from Marathon to Athens to announce the Persian army had been defeated.

Mr Sultan said: “I ran the London one as well. It was always something that I have wanted to do.

“The marathon in Uganda was a unique experience as we were running in rural Africa. My top three were Uganda, London and Athens.”

Whilst running the London Marathon, Mr Sultan finished the race with a man who set the world record for fastest marathon run dressed as a mascot.

Mr Sultan also cycled the length of Britain unsupported. He also created the 'London FUN-RUN Series' which are themed fundraising events aimed at making running fun and accessible.

Kathryn Cheshire, challenge events manager at Macmillan Cancer Support, said: “We’d like to say a massive thank you to Adam for his fantastic fundraising efforts throughout 2015.

"To take on one marathon is a huge challenge and requires great commitment in terms of time and fundraising, so we’re delighted that Adam decided to do this fifteen times in one year.

"Adam is an inspirational fundraiser who is helping Macmillan to ensure that nobody faces cancer alone.”

Mr Sultan recorded his challenge using the nickname Adventure Adam. Donations are still welcome on justgiving.com/adventureadamuk.
