On December 8th in Lexington Kentucky USATF will be holding the Club XC Championships. I am trying to field a team of guys 40-49. All those interested, please email me at armandoxc@gmail.com
I will get back to you with further information. This is a great and highly competitive 10k XC race where everybody shows up.
Meet history and information here: http://usatf.org/Events—Calendar/2012/USATF-National-Club-Cross-Country-Championships.aspx
