Helsinki, Finland ? A Russian man trying to win the Sauna World Championships died after collapsing with severe burns in the final stage of an event that required contestants to sit in a 230-degree room as water was tossed onto a searing stove, officials and witnesses said.

Vladimir Ladyzhenskiy, an amateur wrestler who was in his 60s, was pronounced dead late Saturday after he collapsed alongside reigning champion Timo Kaukonen of Finland roughly six minutes into the final round.

Nearly 1,000 spectators had gathered in the southern Finnish town of Heinola to watch 130 competitors from 15 countries, waving flags and cheering on the contestants before medical workers pulled the shaking and bleeding men out of the sauna.
