# Masters W40 marathon world record progression

Masters W40 marathon world record progression is the progression of world record improvements of the marathon W40 division of Masters athletics. Records must be set in properly conducted, official competitions under the standing IAAF rules unless modified by World Masters Athletics.

The W40 division consists of female athletes who have reached the age of 40 but have not yet reached the age of 45, so exactly from their 40th birthday to the day before their 45th birthday. Marathon running is not normally seeded into age divisions so all of these records were set in marathon race open to most other age groups.
