French freediver Arthur Guerin-Boeri has set a new CMAS World Record for the longest under-ice swim wearing only a swimsuit.
Guerin-Boeri swam 105m/344.5ft with a neck weight — but no fins — in a frozen quarry near Ottawa, Canada on March 8th.
In March 2017, Guerin-Boeri set a men’s CMAS world record with a 175m/575ft swim with a monofin and wetsuit.
