 The IAAF, now World Athletics did not go back to recognise the world best performances set at Carlsbad, which left a dilemma of known superior performances at Carlsbad and inferior world records that will last until the performances at Carlsbad are recognised or surpassed.Another annual American race, Freihofer's Run for Women, also regularly has elite women competing in the road distance, as does the BOClassic in Italy.Elite racing almost exclusively takes place on the track for this distance.
