They spent their summers competing in AAU basketball tournaments and their fall seasons winning soccer championships for the Oxon Hill Boys & Girls Club.

Once in high school, Mechelle and her sister would make one of the most significant decisions in their lives and decided to quit basketball to begin their Track & Field career.

Mechelle's 4 × 400 m relay team won the state title three consecutive years and came in third at the National High School Indoor Track & Field Championships in 1997.

[4] With nationally recognized success, Mechelle also brought home championships competing in the USATF Junior Olympics for the Rising Stars track club.

After going through a rigorous process of elimination, both Mechelle and her sister chose to run track at the University of South Carolina where they both received full scholarships to do so.

She moved to New York City and worked at one of the world's top advertising agencies, Young & Rubicam, serving Xerox and the United Negro College Fund.

[7] After two years at Young & Rubicam, Mechelle decided to return her focus to track and field; she relocated to North Carolina to begin a fully committed training regimen.

Outside of track & field, Mechelle uses her platform, Do It Afraid!, to encourage individuals to recognize their self-worth and move forward in life facing their fears head on.
