Muscle Milk Returns to Support the 2011 Lucas Oil AMA Pro Motocross Championship

MORGANTOWN, W.Va.
(May 18, 2011) - MX Sports Pro Racing, and Alli, the Alliance of Action
Sports, announce the return of Muscle Milk, a lactose-free,
protein-enhanced beverage, in its role as a top-tier sponsor and the
"Official Protein Provider" of the 2011 Lucas Oil AMA Pro Motocross
Championship. As part of its support of American Motocross, Muscle Milk
will once again implement the popular Recovery Rider of the Day Award
at all 12 rounds of this season's championship.

Muscle
Milk broke into the sport of motocross at the start of the 2008 season
as a presenting sponsor of the MDK KTM race team. In 2010, the brand
signed on as title sponsor of the Joe Gibbs Racing MX team. Since then,
its presence within the industry and popularity amongst motocross fans
has grown exponentially. This season, the Muscle Milk/Toyota/JGR squad
features Justin Brayton, who has been a Muscle Milk athlete since 2008,
and newcomer Davi Millsaps - each of whom will compete for a chance at
the 450 Class title.

During
Muscle Milk's introductory season in 2008, the brand also became an
integral part of the Lucas Oil AMA Pro Motocross Championship. In an
effort to further establish itself in the world of motocross and become
a name synonymous with the sport and its athletes, Muscle Milk
introduced the Recovery Rider of the Day Award. This summer, Muscle
Milk will recognize the 450 Class rider who boasts the best increase in
finishing position from Moto 1 to Moto 2, excluding any riders who
record a DNF, at each round of the championship by awarding him $500
for his tenacity.

"The
Recovery Rider of the Day is all about acknowledging riders who were
able to recover from Moto 1 to Moto 2," said Muscle Milk's Shane
McCassy "Motocross is an intense sport with many variables, so bad
motos are part of it. With Muscle Milk's key functionality being
exercise recovery, this award ties perfectly into our product."

The
added incentive for the riders who experience adversity out on the
track is just one of the many ways in which Muscle Milk supports the
sport of motocross. Additionally, the brand's mobile training center
not only provides a place for riders to grab a Muscle Milk after a
tough day on the track, but also gives them a place to warm up, cool
down, or workout with some of the latest equipment from Orbea Bicycles
and Concept 2.

The
2011 Lucas Oil AMA Pro Motocross Championship kicks off this Saturday,
May 21, with the Rockstar Energy Hangtown National in Rancho Cordova,
Calif.
