Video: The Toughest Swimming Race You've Ever Seen

Swimming isn't a sport I write about a lot on this blog, and if I do it is usually because someone is covering an especially impressive distance, or it is part of a major triathlon. But in this case, it is worth pointing out the insane event that is the Redbull Neptune Steps, a race that sends competitors on a 420 meter sprint swim up the Maryhill Locks in Glasgow, Scotland. The swimmers must make their way up stream, then climb up eight different locks on their way to the finish line. To say that this looks exhausting would be an understatement. It is also safe to say there aren't many other events like this in the world.
