I am taking on the challenge of climbing into the Hintertux glacier cave system at a height of 3.200m and swimming in the -1°C cold glacial lake channel. My goal is to swim the 80 m channel back and forth at least once, without a swim suit. I will be supported by Daniel Ruppert (http://www.danielruppert.de), Wim Hof instructor and breath and cold trainer,  and Christof Wandratsch (http://www.wandratsch.de), Extreme swimmer and multiple world champion and world record holder.

Please join my challenge by donating to Greenpeace to support their work to win a historic Global Ocean Treaty at the UN negotiations in March 2022 to protect at least 30% of the world’s oceans as sanctuaries by 2030 (30x30). Scientists agree that this is urgently needed to support people, save wildlife and fight climate breakdown. THANK YOU!!!
