Dutch athlete Sifan Hassan has entered four events at the Paris Games, the marathon plus the 1 500, 5 000 and 10 000 metres, according to entry lists published by World Athletics on Friday.
The twice Olympic gold medallist could scratch from any race before the Games kick off on 26 July, and official start lists will only be available on the eve of the Olympics.
But the ambitious potential agenda has caught the eye of track fans, three years after she tackled the 1 500, 5 000 and 10 000 in Tokyo, winning the longer distances but settling for bronze in the 1 500.
She proved a lethal factor in the marathon, winning in London and breaking the tape in Chicago in the second-fastest performance of all time in 2023.
She finished a disappointing fifth in the 1 500 last week at the FBK Games but said she was undeterred.
"This sport keeps on teaching. I couldn’t show my best yesterday, but it only makes me more determined," she wrote on social media.
The Paris field includes 36 defending champions across 48 events, according to World Athletics' announcement, with world record holders including Kenya's Faith Kipyegon, American Sydney McLaughlin-Levrone, Norwegian Karsten Warholm and Swede Mondo Duplantis.
