Melissa Jefferson-Wooden: World's fastest woman sets future goals on 'World Record' after gold-medal sweep in Tokyo

After claiming the crown as the world's fastest woman following her gold-medal sweep at the World Championships in Tokyo, Melissa Jefferson-Wooden now has her future goals on breaking the women's sprint world records.

The American sprint queen enjoyed a year of dominance on the track, which climaxed in Tokyo, where she blazed to the 100m world title in a championship record of 10.61s, stormed to 200m win in a massive personal best of 21.68s, and led the charge for Team USA's 4x100m relay squad blasting to the gold medal.

With her victories, Jefferson-Wooden became the first American woman in history to win the sprint double titles at the world championships and only the second woman after the legendary Shelly-Ann Fraser-Pryce (Moscow 2013), to attain such a feat.

Her triple crown in Tokyo, which instantly placed her in the same stratosphere as some of the greats, as well as staying undefeated in the 100m this season, earned her the undisputed bragging rights as the world's fastest woman.

“The biggest lesson I got from this year is learning that if you lock in and dial in on things you say you want to achieve but also put the hard work in on top of that, the sky is the limit,” she said in an exclusive interview with CNN.

“There are so many things out there that I’ve accomplished this year. But there’s so many more things that I do want to accomplish.”

Despite her historic achievements this season, Jefferson-Wooden has bigger ambitions and wants to extend her dominance with the goal of breaking the late Florence Griffith-Joyner's long-standing 100m world record of 10.49s.

“The biggest thing for me if I want to break the world record and become the world record holder, it’s not going to be chasing the time,” she added.

“It’s going to be doing very similar to what I did this year, and that is just focusing on me, focusing on my execution, listening to my coaches, and then surrounding myself with people who are going to get me where I need to be.”

With greater ambitions comes a bigger work ethic and pressure, which Jefferson-Wooden is ready to embrace the challenge before she hangs up her spikes.
