I won't claim to know anything about her, but according to Wikipedia she's competed at 2 Olympics doing 5k in one and 5k & 10k in the other. So not sure how she is defined as a steplechase specialist?

reading the article helps :)

"Grøvdal, 30, specialises in 3000m steeplechase and has won European bronze medals over both the barriers and at 10,000m."

it depends what you read
her best result is 7th in Rio oly games over 5k . She obviously does both very seriously.
