During her U.S. Soccer Hall of Fame induction on Saturday, USWNT legend Lauren Holiday recounted the “hardest thing” she ever went through.

While pregnant with her daughter in 2016, Holiday — who retired from soccer one year earlier — learned that she would need brain surgery in order to remove a tumor.

“Unlike the toughest moments I had endured in sports, I couldn’t work or train my way out of it,” an emotional Holiday said during her Hall of Fame induction speech. “I had to come to terms with the fact that I couldn’t outrun the fear of leaving my family too soon.”

Holiday, who won two Olympic gold medals and one World Cup title during her USWNT career, went on to explain her realization that soccer had prepared her for the unbearable feeling of waiting for her surgery.

“When I would run fitness, I would figure out the exact timing I would need to accomplish my goal. I would tell myself while running, ‘You can do anything for a minute. You can do anything for two minutes.’ Hell, on the beep test, you can do anything for 12 minutes, but you got to get to level 20.”

Holiday said she broke up the waiting — first for her daughter’s birth, and then for her brain surgery — with the belief that she just had to get through the next hour, or the next 10 minutes.

“I would repeat Psalm 30, verse 5: there may be pain in the night, but joy comes in the morning. And each time I repeated this to myself, I found the strength to keep going.”
