The proportion of pupils who cycle to school each year has reached record levels in Scotland, according to new figures.

Findings showed 3.7% said they got on their bike for the commute in 2017, up from 2.8% in 2010.

The Hands Up For Scotland survey also revealed the number who walk to school has continued to fall.

Sustrans Scotland's national director John Lauder said: "The survey is crucial in helping local authorities and partners to build a more accurate picture of how Scotland's children travel to and from school, and helps to pinpoint areas where more work can be done.

"It is particularly encouraging to see a continued rise in the number of pupils cycling to school each day.

"Research has shown that increased physical activity can help us lead healthier - and happier - lives.

"By encouraging young people to travel actively for their journey to school, we can ensure Scotland's children develop healthier travel habits that will be continued later in life."

Now in its 10th year, the Sustrans Scotland survey registered the highest-ever number of participants - 515,005 across nursery, primary, secondary, independent and special educational needs schools.

Active travel is still the most frequently reported mode of travelling to school.

Of the 48.8% of pupils who said they normally get to school in an active way, 3.7% said they used their bikes and 2.8% said they arrived on scooter or skated to school.

The cycling increase was highest in secondary schools, which saw a 0.4-point increase to 1.3% in cycling levels over the past year.

A total of 16.5% of pupils said they normally travelled by bus and 24.5% said they travelled by car or taxi while 9.7% said they went via Park and Stride.

There were 42.3% who said they walked, which was a decrease from 2016.

This drop has led to calls for local authorities to invest in infrastructure and projects to reverse the trend.

Stuart Hay, director of Living Streets Scotland, said: "This decline is the result of a lot of local factors, including school mergers creating larger catchment areas and parents being concerned about safety around the school gates.

"However, it's a decline which can - and should - be reversed.

"Schools in the 22 Scottish local authorities taking part in WOW - our year-round walk to school challenge - are seeing significant increases in the number of children walking to school.

"All local authorities need to be investing in projects which promote the benefits of walking, as well as better infrastructure around schools in terms of crossings, speed limits and well-maintained footways, so that more families can enjoy the benefits of walking to school."
