Families are being urged to take part in a survey which will help assess the value of Sheffield’s outdoor economy.
Sheffield Hallam University’s sport industry research centre is undertaking the project for Sheffield Council to look at how the country’s greenest city benefits from its great outdoors.
More than 500 people have already completed the survey online.
Everyone who takes part will also be entered into a prize draw to win £100.
Organisers say it is open to everyone living in Sheffield, whether they take part in outdoor activities or not.
The results will calculate the importance of outdoor recreation to local people and visitors. Visit http://www.sircsurveys.com/f/612316/5db3/ before May 30.
