There are many different sanctioning bodies in a layered fashion in the world of BMX. At the top is the Union Cycliste Internationale (UCI). It is the world governing body for all cycling disciplines. Next is the Canadian Cycling Association (CCA) who are sanctioned by the UCI to organize and promote cycling in Canada. Our provincial branch of the CCA is the Alberta Bicycle Association (ABA). The mission of the ABA is to act as the organizing body which promotes all aspects of cycling in Alberta. Last but not least we have the Alberta BMX Association. This is the main "workhorse" for hosting the Alberta Provincial series, as well as promoting BMX as a strong discipline within the ABA.
Because there are so many sanctioning bodies - there are also a lot of rules. While it would be nice if these were combined into one all-encompassing document, this is unfotunately not feasible.
