King athletic director David Hicks made the announcement Tuesday.
"King is a great institution and the move just really didn't fit well for my career and family," Dalton said in a statement from the school. "I realized moving was not the best option for me or my family, and King was gracious enough to welcome me back. I'm excited to focus on the distance and cross country program here at King. I know Coach Williamson will do a great job leading the track and field squads."
Under Dalton's leadership, the King track and field and cross country teams rose to regional and national success over the past three seasons. The Tornado won four Conference Carolinas championships and made two NCAA Championships appearances as a team, with several other individual qualifiers.
"Peter is one of the top distance coaches in the country," Hicks said. "When he contacted me about the possibility of returning to King, it was a very easy decision. I'm extremely excited that he will continue to lead our cross country programs."
Amanda Williamson, named head coach of both cross country and track and field after Dalton's departure, will remain as the head coach of the men's and women's track and field programs, Hicks said.
"Amanda is one of the top track athletes in the history of King track and field," Hicks said. "She has spent the past three seasons as an assistant coach with a very successful program, and our search committee overwhelmingly believes she is the right person to lead our men's and women's track and field programs. This situation has not changed that fact. I'm excited about the future of our track and field programs under her leadership."
Williamson said Dalton's return will allow her to "put all my focus on track and field."
Dalton will also serve as the assistant track and field coach, focusing on the distance program, and Williamson will support the cross country programs as assistant coach.
