Nigeria's first bobsled team running for pride and legacy

Seun Adigun told herself her athletic career was done after she ran her last race at the 2012 Summer Olympics in London. But for some reason, she couldn't bring herself to tell the world.

Three years later, she realized: Adigun wasn't retiring — she was readying for a new sport. And her years competing as a 100-meter hurdler were great preparation what would come next.

"It was the speed and the power and the strength that I needed to be able to be a successful bobsled athlete," she said.

Adigun, 31, soon convinced fellow former runners Ngozi Onwumere and Akuoma Omeoga to join the team as brakemen. But they wouldn't just be newcomers to the sport.
