In order to feel alive, sometimes you have to break away from your comfort zone and dance along the edge of sanity, taunting the Grim Reaper. Pain wakes you up to a more profound mindset where your mundane, everyday worries have the volume turned down. Extreme activities, such as ultramarathons, are a form of therapy that puts life into perspective.
A standard full marathon is 26.2 miles of hard work and dedication, but this list is going extreme with races that go beyond the norm, heading into the territory of suffering and self-discovery. In compiling this list of the toughest races in the world, we chose insane ultramarathons that are flat out brutal, making us cringe. These races are only for insane athletes who are ready to face incredible ascents and descents, hellish terrain, unbearable distances, and killer temperatures. You have to be a special type of monster to even consider running any of the races on this list. We definitely wouldn’t wish this type of torture on anyone, but we admire those who have the guts to sign up.
Checking Your Fitness Level
If you’re insane enough to sign up for one of these extreme marathons, we highly recommend you speak with your primary physician first. These ultimate races aren’t for everyone, so you need to be absolutely sure you’re willing and able to withstand the torture. If you just so happen to get the green light from your doctor, make sure you train safely to prepare yourself for the worst. We even recommend a personal trainer to help you prepare for one of these soul-crushing events. Also, you’ll want to stay away from the races requiring a special invitation. For all those brave souls who are attempting one of these ultramarathons, we wish you the very best of luck.
The Barkley Marathons
In about 30 years of The Barkley Marathons, only 15 people have finished this incredible test of athletic ability and mental prowess. The almost cult-like ultramarathon is based on the historic 1977 prison escape of James Earl Ray, the assassin of Martin Luther King Jr. It’s a secretive race held in a tiny town in Tennessee where the course is ever-changing. Only 35 runners are accepted each year and the application process is a closely guarded secret. The mysterious race must be finished in under 60 hours and comes to a total of 100 miles. Race bib number one is always reserved for the person crowned least likely to finish one lap and is considered a “human sacrifice.” Yes, this is the weirdest race on the list.
Andes Race Chaski Challenge
Limited to 100 runners, this 100K is the first ultramarathon to be held in Cusco, Peru. It takes place in the Sacred Valley of the Incas and pays tribute to the Incas’ long-distance runners who had to carry messages and orders to other towns and villages. The Andes Race The Chaski Challenge was made for mountain runners, so we advise you not to attempt this vertical run if your knees have trouble keeping you stable. Yes, you will run through picturesque settings and will be surrounded by incredible landscapes, but the real beauty of this ultramarathon is the finish line.

Oh, and if you get first place, you receive about $3,500 in prize money.
