Hardened. Tough. Impressive. Mind-boggling.

It is impossible to adequately describe the athletes who swam 1000 meters in the 0.8°C (33.4°F) water of Semenovskoe Lake in Murmansk at the inaugural Ice Swimming World Championships.

They claim that anyone can do this if they put their mind to it. Anyone who is superhuman, we believe.
