The North American Enduro Coalition (NAEC) was formed to create a uniform standard for enduro racing in North America. Each enduro series and race is unique; the NAEC serves to facilitate communication, provide information and foster enduro into the premier mountain bike race format in North America. And it makes sense to do it that way. Enduro racing is how we like to ride: get to the top, bomb down, and repeat.
The first order of business of the NAEC was to establish a standard rule book for race directors/promoters to adopt or use as a starting point when establishing a series or race. So we put one together. We wrote it with a broad scope so it can be adaptable to enduro races everywhere.
