Charlton Athletic striker Jonjo Shelvey has broken the club record for the distance covered by a player in a game since the ProZone system was installed at The Valley.

Shelvey, the club's youngest-ever player, ran 13.6km (8.4 miles) in the home match against Birmingham City on April 11, breaking Matt Holland's record of 13.4km.

Charlton Head of Sports Science Nick Davies said: "It's an extraordinary figure. He covered more ground in that game than any other player in my own personal experience, and certainly since the club had the ProZone system installed.

"Not only that, but the number of high intensity runs he made was also higher than anyone else."

ProZone is the computerised data system used by clubs to analyse team performance and fitness by plotting the movement and actions of each player throughout a game.

Shelvey has been a shining light in a difficult campaign for Charlton, who were relegated to Coca-Cola League 1 on Saturday.

The club's youngest debutant, who appeared in his first senior game aged 16 years and 59 days, became Charlton's youngest-ever goalscorer on January 3 with a strike against Norwich City in the FA Cup, 55 days before his 17th birthday.

Shelvey, who plays in behind the main striker, followed that up with his first League goals this month, against Southampton and Blackpool.

Charlton manager Phil Parkinson said: "Not only is he a player with great ability and great athleticism, which you need in the modern game, but he has a great desire to work for the team.

"His statistics are exceptional for a player of his age, and underline the future he has in the game."
