Sporty children were handed certificates at a ceremony this week after competing in the Herts Youth Games.
The youngsters were handed the certificates at Hertsmere Borough Offices in Elstree Way, on Monday.
More than 100 children in Hertsmere competed in hockey, netball and badminton tournaments, against people from other boroughs across Hertfordshire in July.
Mayor of Hertsmere, Councillor Pat Strack, who led the ceremony, thanked the children for taking part.
She said: “Regional competitions like the Herts Youth Games are important, not only because they give young people a chance to explore their sporting potential, but also values that have been at the centre of this year’s London Games.
“I want to thank everyone who took part, and everyone who helped to organise the event, especially the team managers and parents.
“Without whose support the games could not have happened.”
Hertsmere was crowned third overall in the competition, which took place at the University of Hertfordshire de Havilland campus in Hatfield.
Councillor Brenda Batten, portfolio holder for leisure, culture and health, added: “All those young people who took part in the games took something away with them they will remember for the rest of their lives.”
