Svetlana Romashina, who shares the Olympic record with five synchronized swimming gold medals, plans to return to competition by next year for the first time since the Rio Games, according to Russian news agency TASS.
Romashina, 28, said soon after the Rio Olympics that she was taking a break from the sport but harbored Tokyo 2020 ambitions, according to Russian media.
She had a baby girl last fall and has been an assistant coach with the dominant Russian synchro team that just won all eight events it entered at the European Championships.
Romashina was part of Russian Olympic team and duet sweeps with Natalya Ishchenko in 2012 and 2016.
