There are some truly great ice freedivers in Russia, BUT
Johanna Nordblad, of Finland, dived 103m under ice in 2 minutes and 42 seconds.

It is interesting and inspiring to see how these great athletes compete.
ps. any Canadian freedivers out there?
The Russian site set up was better IMO: dive ladder at the end, rope with target metre marks, wide exit hole.
