David Knight claimed the Grand National Cross Country Series in the United States on Sunday.

The Manxman won the final event, the Ironman, and the overall series.

The only rider with a chance of topping Knight, Barry Hawk, dropped out of the race with a broken chain on the second lap.

Knight then battled with Yamaha's Charlie Mullins until getting into the lead past the halfway point and pulling away to victory.

This was Knight's seventh win of the season and the championship makes him the third rider ever to have notched an ISDE Overall Victory, a World Enduro Championship and the GNCC title. Shane Watts and Juha Salminen have also completed the task.

Knight has also won two out of two rounds at the AMA Endurocross - the final round is in Las Vegas on November the 17th.
