• You must obey all USAC rules and Colorado State Laws. That includes riding in the shoulder of the road unless the rider must avoid debris or other object blocking the shoulder or to pass another rider. Failure to obey this rule will be considered crossing the centerline,
• You must know the course. On our website you will find a course map and GPS files that you can use to navigate the course.
• You must not warm up on the course once the race has started. If a marshal or USAC official sees you, you will be disqualified.
• You must be aware of other park users, this is an open course. Be courteous, we are guests of Chatfield State Park and must respect all other park users.
• You are responsible for your own safety. Our marshals and traffic control personnel will do their best to warn you of any vehicle, pedestrian, or bicycle traffic but you are responsible to look both ways when crossing an intersection or coming up to a crosswalk.
• You must read and understand the Chatfield Time Trial Series flyer. The race flyer is now part of our website (this page) and it contains all the details about the series. Most questions we receive are covered on this page, read it and know it before you register.
• You must arrive at the park on time and be at the start line on time. If you arrive at the park late due to circumstances not under your control, see us at the table in the event parking lot and we will do our best to reschedule your start time, but there are no guarantees.
• You must pin your bib correctly. Our spotter and timing crew do not have x-ray vision. If they cannot easily see your bib number, they may not be able to give you your time. You may want to consider yelling out your bib number as you go by the spotter, located just after the last turn towards the finish. We have detailed instructions on how and where to pin your bib here.
• You must verify your own results.  If you believe your results are incorrect or they are not posted, you may contact us and request a review. Click here and scroll down to Other, and My time for my last race is incorrect or missing and there you may fill out a form requesting the review.

You will be issued a bib number for the entire series for the category in which you are racing. Do not discard your bib after the first week – you will need it for all the races!

Your bib number corresponds to your start time. If later you decide to change your start time, you must come to the bib pickup table behind the event parking lot and exchange your bib for a new one that corresponds to your new start time. This is required if you only change your start time for a single week or the remaining races of the series.

Bibs are not transferable to another racer.

The race bib must be pinned correctly on the right side. If the bib number is obstructed by hair or otherwise hidden from the view of the spotter or timers, then you may not receive a time.
