First Annual Muscle Milk TWMX Race Series Holiday GP This Sunday

Despite what you may think, there is no better way to spend the holiday season than at the track. Just like those Hallmark commercials, a day at the track has friends, family, and roaring fires, but is even better because there is racing involved. To better get into the holiday spirit, the Muscle Milk TWMX Race Series will hold our first annual holiday GP this weekend at Glen Helen Raceway. The GP will take place on Sunday, with 35 classes being run over the course of seven motos. Combined with the final round of the Muscle Milk TWMX Race Series Fall Cup being run on Sunday, it creates a full weekend of racing.

There will be classes for riders of all ages, skill, and size at the Holiday GP, including minis, vintage bikes, women, 250/450, and the all-new “Clydesdale” division. What is the Clydesdale class, you ask?  It is for riders of a bigger size, 220lbs or more, and will run in the first moto of the day. Like we said, classes for all ages, skills, and sizes….

To close the day, we have the Team GP where two-rider teams will battle for final bragging rights over the course of a 60-minute run. Don’t have friends? Then run the 60-minutes solo for the Ironman title.
