If you thought a marathon at 26.2 miles was the longest race in the world, you’d be wrong. While most of us would struggle to run five miles, there are some dedicated people out there. These folks take on grueling ultramarathons of more than 200 miles. They trek through mountains, snow, and city streets. Let’s take a look at the 12 longest races in the world right now.
