50,000 m walk (track), women

What to remember

On a track in San Diego on July 13, 2019, Katie Burnett walked 50,000 m in 4 h 29 min 45.56 s. The American was competing at the National Invitational Racewalks, and her pace works out at an average of 11.121 km/h.

What separates race walking from running is a single constraint: one foot must appear to be in contact with the ground at all times, and judges watch for it throughout the race. Usual distances range from 3,000 m to 100 km, held on roads or on tracks.

The women's 50 km walk was contested at the World Championships until 2019, the same year as this mark. The track version has its own record, ratified by World Athletics.
