Prince William and Kate Middleton paid a joint visit to South Wales.
They took a spin class at the Aberavon Leisure & Fitness Centre during their visit.
The royals competed in a spin race that lasted 45 seconds.
Even though she was wearing heels, Kate Middleton won the race.
William appeared pleased with her wife's victory over him.
William was heard saying "Oh God" during the tough contest.
Kate Middleton was named the winner of the "Tour de Aberavon" and was presented with a tiny golden cup.
She gleefully accepted the cup and lifted it in the air as her husband clapped his hands.
After the competition, the mother-of-three was all smiles.
