Blessing Okagbare-Ighoteguonor lost her wig on her opening long jump attempt at a Diamond League meet in Oslo on Thursday.
The Nigerian, a 2008 Olympic silver medalist, leaped 6.21 meters, well off her personal best of seven meters flat.
Her wig came off as she landed and whipped her head back in the sand pit. Okagbare-Ighoteguonor appeared to notice the embarrassing error when she looked back at her mark and smiled.
She went on to finish seventh.
Okagbare-Ighoteguonor later laughed off the incident, saying she has always joked that one day the wig would fall off, according to Norwegian broadcaster NRK.
