Heading into the final round of the 2013 AMSOIL Grand National Cross Country Series, only two points separated Factory FMF/KTM teammates Kailub Russell and Charlie Mullins in the National Championship standings. The 19th running of the AMSOIL Ironman GNCC set the stage for an epic finale as it was a winner-take-all affair at the AMSOIL Ironman GNCC finale and it was Russell who prevailed, clinching his first career XC1 Overall National Championship after three-hours of close racing competition.
