Prince Harry takes a coaching session for young people at Twickenham Stadium, LondonView Album (9 images)
Rugby fan Prince Harry joked he was already "past it" as he helped coach a session for young people at Twickenham Stadium today.
The 29-year-old took part in training with school children alongside former England star Jason Robinson, who threw down the gauntlet to The Prince.
"I'll be looking to see what you've got," the World Cup winner said.
But Prince Harry replied: "I think I'm a bit past it already."
The Prince is patron of the Rugby Football Union (RFU) All Schools Programme, a project to help boost participation in state schools.
Prince Harry, who is often seen cheering England on from the sidelines, put some of his passing, kicking and tackling skills to the test on Twickenham's famous turf.
Robinson, 39, said: "It's just fantastic to see him out here with the kids. "He's dripping with sweat. He's put everything into this, because he is passionate about the game."
Robinson joked with Prince Harry that he could make it into the England squad for the forthcoming World Cup in 2015.
"We're looking for a winger or a full-back," he said to The Prince.
The famous winger, from Leeds, also gave Prince Harry a pair of his boots.
He told him: "I can't guarantee they'll get you into the England team, but you'll be quick."
After the coaching session, Robinson joked: "We're always looking, if any of the England players go down, we've got a replacement.
"I'm not sure what he's like in contact though, although saying that, it was supposed to be a bit of tagging and he was getting bit rough with me."

Prince Harry wore a white T-shirt and blue England tracksuit bottoms as he ran around the pitch for about an hour.
Red-faced and out of breath, The Prince laughed with former England captain Robinson as they tried to out-fox each other.
Prince Harry, who took official RFU coaching qualifications on his gap year, helped coach state secondary school boys and girls from Kelvin Hall School in Hull, Oakbank School in Keighley, West Yorkshire, Oxclose Community Academy in Tyne and Wear, Rokeby School in Newham, east London, and Stonehill High School in Leicester.
The All Schools Programme was launched last year with the aim of showing rugby union is a game that everybody can play and that it is not just for elite schools, like Eton College where Prince Harry went.
Some 104 secondary schools joined the project in 2012/13, and 100 more have signed up for 2013/14.
Overall, the RFU hopes 750 schools will benefit from the scheme.
After helping with the coaching sessions Prince Harry went inside the stadium to meet more school children taking part in a kit design workshop.
The pupils from schools in the South East, who have just joined the All Schools Programme, were brainstorming some patterns for shirts that will be made by Canterbury, the kit supplier for England's rugby team.
Prince Harry asked pupils from The Warwick School in Redhill, Surrey, if the sport was cool at their school. "There are so many good things about rugby," he said. "You've got to make rugby cool. I bet you can if you get your proper kit and put that up at school, you'll get more kids wanting to play."
The Prince then backed England to win the next World Cup on home soil.
"2015 is the year for us," he said. "Get ready for it."View Album (9 images)
