Hijacking an ice floe - sup surfers go extreme in Russia's San Francisco

Sup surfing - or stand up paddle surfing - initially became popular in the quiet waters of the Mediterranean sea. 

A group of Russian fans took the sport to extremes, gathering as many as 28 boarders on a big ice floe in cold waters of Ussuri Bay in Russia's eastern capital, Vladivostok. 

Short but stunning drone footage made by Vladivostok sportsmen paddling ice floe went viral among Russian netizens, gathering dozens of warm comments.

The video was made in the middle of March, when air temperature didn't go above 10C and water was at maximum of 5C. 

Sup surfing is a new but increasingly popular sport in the far east of Russia. 

Many Vladivostok surfers continue paddling even in winter despite freezing temperatures.
