The events were sponsored by Queensgate Shopping Centre, where the trail starts.
“It’s a fantastic opportunity to support the community and help create magical moments for families right in the heart of the city,” said the centre’s marketing manager Verity Swinscoe-Wigmore.
Alongside the trail, there will be other events including The Vegetable Orchestra and Farmathlon Live!
Mr Stainton added: “With Shaun the Sheep leading the way, we are seeing incredible collaboration across Peterborough.
“It is another brilliant example of what can happen when the whole city pulls in the same direction.”
