So Frenchman Pierre Daniel has done something many considered virtually undoable.

The Qatari resident has completed his mission of running 475km across the lengths and breadths of the country in seven days, and is looking for confirmation of a world record attempt (awaiting ratification), reported The Peninsula.

The solo event concluded at the Katara Cultural Village yesterday, with friends, family and sponsors meeting himd cheering him on.

“I’m thrilled to be done and see my family and friends but also can’t wait to tell more and more of the story over coming weeks to inspire others to their own potential and encourage them to go and see what I’ve seen,” he was quoted as saying by Qatar Tribune.

Pierre, in an exclusive interview with Qatar Living, had said he was eagerly looking forward to the run.   

Over the last seven days, Pierre has had less than 4.5 hours a sleep at time, with as little as two hours most nights. During long stage he was moving for 35 hours without making camp. He ended up burning an estimated 48,000 calories.

“The last seven days pushed me to my physical limits and I’ve endured mild hypothermia, 35-hour efforts, heat, headwinds and more. But throughout, I’ve experienced the most amazing sights and scenery of Qatar, been supported by thousands of messages on WhatsApp, Facebook and Instragram,” he said.
