Each year in Supercross, the most anticipated race of the year is often the first: Anaheim 1. The old adage says you can't win a Supercross title at A1, but you can certainly lose it -- so setting the tone for a championship campaign is key from the jump.

Go behind the scenes with supercross title contenders Chase Sexton, Jett Lawrence and Hunter Lawrence as they work through pre-season testing, train for their season debut at A1 and race under the lights in Anaheim.

Will the Jett Lawrence build off a dominant year and entrench his spot atop the sport? Can Hunter Lawrence prove himself as his brother's biggest competitor and usher in a new era of dominance for Honda?

Or will Chase Sexton and his team at Red Bull KTM crack the code to consistent SX results and make a statement to start the season? Go behind the scenes of Race One, directed by Troy Adamitis, from preseason to the gate drop at A1, and find out.
