TheIAAF World Cross Challenge was an annual global series ofcross country running competitions organized by theInternational Association of Athletics Federations (IAAF). Athletes accumulated points in the series' cross country meets during the season, which typically began in December and finished in March prior to the annualIAAF World Cross Country Championships. The series was based upon theIAAF Grand Prixtrack and field circuit and the IAAF hoped to similarly boost the sport of cross country running.^[1] The last series was held in 1999–2000,^[2] after which point it was replaced by theIAAF Cross Country Permit Meetings series which featured similar races but did not have a point scoring format.^[3]
