The burly beer garden worker now packs his laptop and clothes into a waterproof bag which he puts on his back, dons his wetsuit and slides into the River Isar for his journey.

"I used to go by bike or bus or car or on foot and you need much longer. Today the current was quite strong and I only needed about 12 minutes," he said.
"I mostly do this in summer. I am a bit of a wimp, but you can also do it in winter, then I've got a longer wet suit," he said.
