The Skagerrak Strait is a strip of water that separates Norway, Sweden, and Denmark. While it isn't widely known outside of the locals of those three countries, it is a treacherous and choppy section of sea. This is especially true if you're attempting to cross the 130+ km (80 mile) strait on a stand-up paddle board. That's exactly what paddler Casper Steinfath is hoping to do in the video above, challenging his own skills and endurance in the process. This looks like an incredibly difficult undertaking, with some moments that are completely miserable, which of course means it's a great adventure.
