Under New Mexico case law, noncompetes are valid and enforceable if supported by sufficient consideration, if they're related to a legitimate business purpose, and if the time and space restrictions are no broader than what is reasonably required for the business interests that the agreement is designed to protect.  The validity of time and space restrictions is determined on a case-by-case basis.   Bowen v Carlsbad Ins. & Real Estate, Inc., 104 N.M. 514, 724 P.2d 223 

You need to take the noncompete, as suggested, to a contract attorney in your area for review & advice.
