Russian freediver Alexey Molchanov has claimed a world under-ice depth record following an 80m plunge in Siberia’s Lake Baikal – while French freediver Arthur Guerin-Boeri has staked his claim to a new under-ice distance record of 120m in Finland’s Lake Sonnanen.
On 16 March, Molchanov, 34, descended through the 2-degree C water from a hole cut in the metre-thick ice in his bid to complete the deepest freedive under ice using a monofin. The dive took 2min 53sec and was verified by an official from freediving governing body AIDA.
If also verified by Guinness World Records the dive will displace that of Australian freediver Ant Williams, who reached 70m in a Norwegian lake in 2019.
The dive is Molchanov’s 20th world record. He remains unbeaten in three of AIDA’s core depth disciplines: constant weight (130m), constant weight with bi-fins (113m) and free immersion (125m).
Molchanov also claimed the record for dynamic apnea under ice using a monofin in February 2020, when he covered 180m.
And it was a breath-hold swimming record that Guerin-Boeri had in mind as he took 3min to cover a distance of 120m without fins yesterday (25 March). The 36-year-old freediver wore a wetsuit as he swam between a set of ice-holes cut 20m apart, guided by a cable, though next year he plans to undertake a similar feat but without thermal protection.
Guerin-Boeri’s competitive bests, as recorded by governing body AIDA, are 6min 41sec for static apnea, 211m for dynamic apnea no fins and 51m in constant weight no fins.
