Night after night, while most runners escape the summer indoors, Mahmoud Al Khatib heads in the opposite direction.
For more than two months, the 55-year-old has been running 10km every evening along Abu Dhabi Corniche, becoming such a familiar sight that regular walkers now recognise him before he passes. Even the dogs that used to bark at him have stopped, he laughs, as if they have finally realised he belongs there
"I was also born in 1971 and all my children were born in the UAE, so I have always had a special connection with the union which I really wanted to mark through a significant effort."
Now on Day 75 of his consecutive daily 10km runs, Al Khatib is aiming to reach Day 84 in honour of his 84-year-old father, Fathi Al Khatib, who is living with Alzheimer's.
