Hassan took more than ten seconds off another Ethiopian Almaz Ayana’s existing record when she ran 29:06.82 at the FBK Games in Hengelo, the Netherlands on Sunday.
Her record stood for 48 hours before Gidey improved it by a further five seconds, running 29:01.03 to win the Ethiopian Olympic Trials on the same track.
The 23-year-old also broke the 5,000m world record in Valencia in October last year, meaning she becomes the first woman to hold both track distance world record since Ingrid Kristiansen in 1993.
“I expected to run a world record,” Gidey said afterwards. “I’d like to try to break the world record again and break 29 minutes.”
Gidey won silver in the 5,000m at the World Championships in Doha in 2019, while Hassan took gold over 1,500m and 10,000m, but the pair are expected to meet at this summer’s Tokyo Olympics.
Both Gidey and Hassan’s runs are likely to spark more debate over controversial “super spikes”, the introduction of which have seen a plethora of middle and distance track records fall in recent months, following a similar impact where “super shoes” are concerned on the roads.
The pair of races also took advantage of new wave-light technology, which runs around the inside of the track, giving athletes an indication of world record pace.
