Unverified (probably a time trial)
Short Course (41.1 km)
Short Course (150 m short on remeasurement)
The course used for the 1981 race was remeasured at 42.044 km or 151 meters short of the full marathon distance. Since a major part of the shortness was within the Central Park portion of the course, all "five borough" races prior to 1981 must also be considered suspect (1976–1980) and are not considered acceptable for statistical purposes.
Short Course (25.54 mi. = 41.1 km)
Short Course (ca 500 m short)
Note: Mildred Sampson (NZL) ran 3:19:33 in a time trial on 16 Aug 1964 at Auckland NZL.
Short Course (measurements on subsequent course were 150 m short, this course probably short as well)
Short Course (measurements on subsequent course were 150 m short, this course probably short as well)
Short Course (remeasurements of a nearly identical course in 1981 was 150 m short, this course probably short as well)
Short Course (remeasurements of a nearly identical course in 1981 was 150 m short, this course probably short as well)
One Saturday last August, a Mrs. Millie Sampson, a 31-year-old mother of two who lives in the Auckland suburb of Manurewa, went dancing until 1 am The next day she cooked dinner for 11 visitors. In between, she ran the marathon in 3:19.33, presumably a record.
