Masters M50 marathon world record progression
Masters M50 marathon world record progression is the progression of world record improvements of the marathon M50 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 M50 division consists of male athletes who have reached the age of 50 but have not yet reached the age of 55, so exactly from their 50th birthday to the day before their 55th 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.
