We are excited to bring a new event to the Colorado Front Range. The Thunder Valley Short Track Series starts this coming June. We will be hosting 3 short track races at the Thunder Valley moto track on C470/I70 area. Races will be on Tuesday nights June 10, June 24 and July 8. As you can expect, you will be treated to an amazing race scene, exciting atmosphere, professional timing, super fun terrain, a volunteer group that is second to none, and of course, support from our sponsors. This is seriously a good time for the whole family and a great way to spend a summer evening.
If you are a student or a parent/guardian of a youth rider and thinking about racing one of our events, WE WANT YOU THERE! We don’t want you worrying about the cost of registration, so we developed our scholarship program to give athletes of all ages and abilities an opportunity to race. Please consider applying for one of our scholarships. Click logo above to get started.

Course: The course and length will vary each week, but plan on distance to be around 0.6M – 1.0.
Equipment: All bikes are legal for the race, with the exception of E-bikes. We can’t overstate the importance of your bike running in top condition on the day of the race. Like you, it will be challenged. And, it’s your friend. Help a friend out.
Spectating: There are many ways to view this event. Please consider routes that don’t interfere with riders as you make your way to a spectating spot. A map will be provided as we get closer to race day.
Number Plates: All Racers will be issued a chipped number plate. Treat it well.
Timing/Awards: We work to get results and awards as quickly as possible.
CANCELLATION POLICY: Rattler Racing does not offer refunds. If we are forced to cancel PRIOR to race day, a transfer to another TVST race will be offered. If we are forced to cancel DURING race day due to inclement weather, we will be unable to offer a refund. If you would like to transfer your entry to another rider prior to race day, no problem. Just drop us a line and we will issue a voucher for the new participant. No charge for transfers. If you need to defer, we will happily issue a voucher credit for a Rattler event in the next 12 months. This will incur a $10 fee. Deferral requests will not be accepted 2 days prior to race day or anytime there-after. Thank you for understanding this policy!
