Ksenia Saprykina Sets Unofficial Junior World Record in 400 IM – Surpasses European Senior Mark - Finswimmer Magazine

On May 2, 2025, during the Finswimming Russian Championship held in Novosibirsk, 17-year-old Ksenia Saprykina delivered a sensational performance in the women’s 400 metres immersion (400 IM), stopping the clock at 2:57.62. The time not only surpasses the current junior world record but also goes under the official European Senior Record—a truly remarkable feat for such a young athlete.

Despite the extraordinary nature of her swim, the performance is classified as an unofficial Junior World Record due to the absence of anti-doping controls, a mandatory requirement for official recognition by CMAS. She set also the unofficial WOrld Record on 200 IMM on March 2025.

Unofficial World Record 200im women – Saprykina Ksenia

Ksenia’s time outshined the existing European Senior Record of 3:00.41, set by fellow Russian athlete Anastasiia Iliushina (born in 1994) on 15 July 2024 during the European Championships in Belgrade, Serbia. While Iliushina’s record remains the official benchmark, Saprykina’s sub-three-minute swim is an early signal that the next generation is already challenging the sport’s highest standards.

Representing the Rostov region, Ksenia is continuing a family legacy in finswimming. She is the daughter of Igor Saprykin, a former World Champion and World Record Holder, who was among the sport’s elite 20 to 25 years ago. With her stunning underwater technique, precise control, and evident race maturity, she seems destined to carve her own path into finswimming history.

Her result in Novosibirsk has sparked attention across the international finswimming community. Even though it remains unofficial, the performance places Ksenia among the fastest women ever in the 400 IM and solidifies her reputation as one of the most promising young athletes in the sport today.

As she continues to develop and gain international experience, Ksenia Saprykina is undoubtedly a name to watch in the years leading up to future World Championships and potential record-breaking swims under official conditions.
