As night fell, Dr Alsharkas was concerned about swimming in total darkness, but was spurred on by the thought of family waiting for her on the other side.
She was greeted on French shores by sister Hela, who is currently studying in France, and her mother Huda, who successfully applied for a temporary visa so she could cheer her daughter at the finish line.
She said: “I was very happy to see them all waiting on the beach. My mum was wading in the water to hug me first thing but I ran away from her. If I touched her before I cleared the water I would have been disqualified!”
Dr Alsharkas, left Syria in 2012 to study for a Masters in economics at Essex. She went on to take a PhD and now lectures in the University’s Department of Economics.
Swimming has always been a passion for her and before coming to the UK she was a swimmer with the Syrian national team and was the national 50m and 100m butterfly champion.
As well as raising awareness of the plight of refugees from Syria, Dr Alsharkas took up the challenge to raise money for Sawa for Development & Aid to support children in refugee camps in Lebanon. Donations are still welcome, so please visit her JustGiving page.
