Children across the east are taking part in the county's largest school competition involving cycling, scooting and walking.
It comes amid rising concern about child obesity with research showing that many young people have done far less exercise during lockdown.
‘The Big Pedal’ is run by the charity Sustrans, with the aim of getting people to ditch their car and opt for an alternative way in. They hope to improve mental and physical health as well as reduce stress and anxiety.
One of the schools taking part is Grange Primary Academy in Kettering.

Meanwhile young people at Pot Kiln Primary School in Suffolk say they may keep up cycling after enjoying the journey in.
The event, which is in its 11th year, is especially important this year after almost one third of children reported not leaving the home during a typical day of lockdown.
Young people are encouraged to get at least one hour of exercise a day, and organisers of the competition hope this will encourage people to get outside.
