The IAAF is the international governing body for the sport of athletics. As of 2009, the national governing bodies of 213 countries[nb 1] and territories[nb 2] are affiliated to the IAAF as National Member Federations.[6] According to the IAAF, their lists of national records "mainly include official records as recognised by various national federations" and notes that in some cases "federations recognise invalid performances".[1] Specifically, the Boston Marathon is listed as hosting two current continental (or area) records, yet was invalidated for the world record because it is a point-to-point course, with a greater than allowable elevation drop—performance aiding situations.[7]
