Prince Harry gave high fives over the River Tyne as he joined Steve Cram and Jonathan Edwards in training runners taking part in the London Marathon for mental health charity Heads Together.
The trio put on the coaching session on the Newcastle Gateshead Quayside for competitors from across the North East and Scotland running for the organisation.
Harry joked with Cram, who was dressed in shorts and a headband, about a bandage on his knee as the three of them stood on the Millennium Bridge and encouraged runners as they did shuttle runs back and forth.
Joking that one runner looked like Johnny Vegas, he shouted for them to catch the ones in front.
He also greeted some of the by-standers, including a little boy in a bobble hat, asking if they had been tempted to join in the training.
Spearheaded by Harry along with the Duke and Duchess of Cambridge, HeadsTogether aims to change the national conversation on mental well-being to a positive one.
Steve Cram told ITV Tyne Tees it was nice to have the Royal Family involved in the project.
