Siar Ozgul came to London four years ago from Istanbul to make his dream of becoming a world champion a reality.
Most people are still in bed, but Siar Ozgul starts eight kilometre run through the cold streets of London before the sun rises over the city.
"The reason I came to London is because I have a specific ambition," said the 23-year-old who left his home in Istanbul four years ago.
"I want to be a world champion."
TRT World's Matthew Moore spent time with Ozgul in London.
