As a substitute, she determined that her future was with the nation of her beginning.
Echikunwoke made her debut on the World Championships in Eugene in 2022, ending twelfth within the last.
She was a shock winner of the 2024 US Olympic trials, throwing a season’s better of 74.86m.
She bettered that within the Stade de France on Tuesday night as her mark of 75.48m positioned her behind Canada’s Camryn Rogers.
“I felt fairly safe coming into the competitors. It is a chance of a lifetime,” Echikunwoke stated.
“It is electrical – simply being on the US staff, being within the last, coming into the stadium and listening to everybody [be] so loud.
“[To be] the primary lady to medal (in hammer throw) for the US, it is actually an honour.
“It is actually a vindication. I wished the expertise.”
At the moment, Echikunwoke stands proud, having moved on from the chapter of her profession the place she may have competed below the flag of Nigeria.
“I knew there was all the time extra, even from that point,” she stated.
“I’ve forgiven the previous and we simply transfer ahead.”
A consultant of Nigeria’s sports activities minister wouldn’t be drawn on her success.
“We’re specializing in our personal athletes now, not the one which has gone to characterize [an]different nation,” the spokesperson advised BBC Sport Africa.
The AFN didn’t reply to the BBC’s request for touch upon Echikunwoke’s silver medal.
