Johnson won the 2016 Sir Walter Miler in a meet, outdoor North Carolina state and personal record of 4:25.04 (and her first sub-4:30 Mile), and six days later, at the third stop on the BBTM Grand Prix Tour 2016, she won the ServiceNow West Chester Mile, stopping the clock at 4:31.33.[4]
Johnson coached cross country and track at Huntington University beginning in 2018. Following the arrest of the head coach and Johnson's husband, Nicholas, in 2020 for child seduction and kidnapping, Johnson was named head coach.[5][6] Athletes filed a Title IX lawsuit in 2022 alleging sexual abuse by Nicholas and a program of forced doping by the coaches. Johnson was fired. The lawsuit was dismissed in 2023.[7]
Johnson continues to coach former Huntington University runner, Addy Wiley.[8]
At Huntington University, Johnson earned All-American honors in track, cross country, and basketball. On her multi-sport background, she said, "I started playing basketball when I was 4 years old and that was my main sport all the way through college. I only began to focus on running once I graduated, so I'm pretty new to the elite level of track and field."[citation needed]
