After taking over Lake Elsinore Motorsports Park, the Muscle Milk TWMX Race Series moves to Glen Helen Raceway for round four of the Summer Cup. With the racing on the track is an intense as the summer heat and with hundreds of racers from across Southern California competing at each round, there is no best test of skill than lining up beside a gate full of riders.

With its dramatic climbs, jumps, and speeds, Glen Helen is the benchmark for motocross racing. World famous due to hosting both the AMA and FIM professional championships, there is a certain amount of prestige that comes when one pulls into the front gates. Our previous events at GH have drawn record numbers along with legendary racers to the track, and we expect to do the same this weekend. With only two rounds left in the championship, many titles hinge on the outcome of this weekend.

Online entry for round four of the Muscle Milk TWMX Race Series at Glen Helen is now open at Online entrants are automatically entered to win a prize package courtesy of Muscle Milk. This, in addition to payment via PayPal and increased odds at a better first moto gate selection make signing up on the web a viable option.  Early entry closes FRIDAY, AUGUST 10TH, AT MIDNIGHT.

Over night camping (free) gates open until 9pm Saturday night.
Gates open at 6:30am Sunday, practice at 8:00am
