Anza, California's Cahuilla Creek hosted the opening round of the 2013 Muscle Milk TWMX Race Series, a six-race championship, and the natural layout of the Riverside county course served as the perfect kickoff to a new season. Carved across a series of hills, the traditional motocross track is known for its sandy dirt, elevation changes, and challenging obstacles. It is a favorite stop of many Southern California riders and serves as a testing facility for many professional teams preparing for the summer Nationals.

The Muscle Milk TWMX Race Series has been well received by participants, evident in the number of entries at each stop, but this has led to long, sometimes brutal days at the track. These issues sent us to the drawing board for the 2013 season and for the Spring Cup and beyond, an integral format change was made. With every facility the series visits having two tracks on site, classes are separated by skill level and run their motos on either the "Amateur" or "Expert" layouts. Both tracks started from the same starting gate, but split either left or right, depending on the class. This allowed two classes to race simultaneously and shorted the race day drastically.

The split start, pictured here, was the major aid in getting through the day a little more quicker. Basically, racers on the main track would turn right here and racers on the intermediate track would turn left. Two races going simultaneously was a simple idea and even more effective for a shorter day.

The on-track action was intense, as always, and the level of talent was high in each class. Dylan Anderson battled Patrick Hannah for 250 B class supremacy and diced throughout the first moto, with the win going to Hannah. The second moto would effect the overall standings dramatically, as Hannah could only muster a sixth while Anderson held on to second and claimed the overall. Hannah then took on the 450 B ranks, but his 3-1 scores were bested by Cody Baker's 1-2 finishes. Andrew Silverstein and Lawson Bopping ran the day's Pro divisions. Silverstein won both 250 A motos while Bopping swept all four 450 A and Pro Open motos.

Lawson Bopping put on a clinic with his speed in the pro classes. He finished 1-1 in both 450A and Pro Open.

Round two of the Muscle Milk TWMX Race Series Spring Cup will take place at the oldest motocross track in California, the historic Perris Raceway, on April 7th.
