The Muscle Milk TWMX Race Series Spring Cup kicks of this weekend at Cahuilla Creek Motocross in Anza, California. The first round of the six race series is set to be epic, as the weather forecast calls for clear skies and cool temperatures. Cahuilla Creek’s previous round of the Muscle Milk TWMX Race Series was nothing short of successful, and this Sunday’s round is set to outdo the January event.

The Muscle Milk TWMX Race Series will pick up right where it left off in terms of experience, as the season opener will once again have a full roster of classes for racers of all skill levels to compete in. The track’s gates will open at 6AM and the day will begin with practice taking place at 8 AM. The first round of motos will start just after the final practice session has concluded. A dedicated vendors row will have all that a racer would need for a day at the track, thanks to BTO Sports and MTA. Bell Helmets will be on hand allow racers a chance to try on their latest high-end lid, the Moto-9, and One Industries will roll out their much awaited Spring 2012 gear line.

An open practice will take place on Saturday from 9AM to 3PM for those who would like to dial in the Riverside County circuit. Practice is $20, and overnight camping is available for $10.
