Visitors to central Paris were treated on Sunday to the sight of hundreds of aproned waiters surging through the mediaeval streets, in a one-of-a-kind race designed to show off the profession months ahead of the Olympic Games.

Men's winner Samy Lamrous and top waitress Pauline Van Wymeersch walked the two-kilometre route in 13 minutes 30 seconds and 14 minutes 12 seconds respectively – each carrying a tray with a croissant, espresso and glass of water.

"We do this for 12 hours every day, including weekends and holidays," said Van Wymeersch, who works at cafe Le Petit Pont a few hundred metres from city hall.

Her race-winning secret was "20 years on the job and good legs", she said.

As well as their medals, both winners would receive a night's stay in a swanky hotel, said city water authority Eau de Paris, which sponsored the event.

"Congratulations to everyone who took part," the body wrote on X (formerly Twitter), alongside a video of Lamrous panting for breath as he broke through the tape.

A jury was waiting at the finish line to judge both contestants' times and how much of their beverages might have slopped over an unbalanced rim.

Hundreds of spectators lined the route or applauded from roadside cafe tables as the servers, jaws clenched, piloted their trays through the streets, seeking to keep the precious cargo intact.

Joshing as they went, some pulled off acrobatic movements with their trays as they slipped through a gap to overtake.

"My thighs are a bit strained but it's mostly a question of concentration," said Lamrous.

"You have to keep it balanced with all these people cheering you on. In the end, I managed to come back from behind, Paris style," he added of his first-place victory. (AFP)
