This LDR Guide is a summary of key Pacific Association/USATF LDR rules, policies, and operating procedures. Although its focus is on the association’s LDR Road Grand Prix, many of the points are also applicable to the cross country and MUT running Grand Prix. An index of sections that also apply to Cross Country and Ultra running is provided at the end of this document and on separate pages linked above. This Guide is provided as a service by Pacific Association LDR to all LDR clubs in the Pacific Association. Clubs should take responsibility for making this Guide available to all people in the club that may benefit from its use: club officers, the club USATF contact, club LDR Committee representatives, and club LDR team captains, at a minimum.
