Ten year-old Oliver Starr has won a Transport for London competition.
Students from schools across the 33 London boroughs were invited to write a pledge to encourage more active ways of travelling to school.
Oliver, a pupil at Rosh Pinah, was one of two winners from the borough of Barnet. His pledge read: "I would like it if more people would play sport more fairly and don't cheat. I want people to try to walk to school more.
"I want to grow up in the world where everyone is encouraged to do everything, no matter what their ability."
The competition was run by the Big WoW (walk once a week), an annual event organised by Transport for London, London boroughs and the charity Living Streets. It is also responsible for launching International Walk to School Month, which this year took place in October.
This year the Big WoW was Olympics-themed with schools taking part in a walking relay.
The winning pledges were inserted into the relay baton, which will be on display at the 2012 Olympics.
Oliver tells People: "I enjoyed taking part in the relay pledge as I believe people of all abilities should just do the best they can."
