If you’ve been joining races, I’m sure you’ve heard about ultra running. But do you know when a run becomes ultra running? Like you, I had not the slightest idea of what it was when I first heard it, but over the years of researching and joining such competitions, I learned more and more about it.
A run becomes ultra running if it exceeds the marathon distance which is 26.2 miles (42.195 km). Common marathon distances are 50 km, 100 km, 50 miles, and 100 miles but there are races that reach 300 miles. The longest ultra-running competition in the world reached 3,100 miles.
Ahead, we will discuss more ultramarathon distances, the longest ultramarathon race, and the longest distance ever run by a human. So if you’re interested in learning about ultramarathons, I highly recommend you read along.
What Distance is Considered Ultramarathon?
An ultramarathon is a run that goes beyond the standard marathon distance which is 26.2 miles or 42.195km.
The most common distances are 50 km and 100 km which are both considered World Athletics record distances but there are ultra races reaching 200 miles or more.
Most of these events last 8-24 hours, however, there are multi-day races that last for several days continuously to several weeks broken up in stages.
Although the World Athletic record ultramarathons usually take place on the road, there are many ultramarathons that take place on trails and mountains.
Some of the most popular ultramarathons are:
|Ultra Trail du Mont Blanc||The Alps||110 miles|
|Comrades Marathon||South Africa||55 miles|
|Fire & Ice Ultra||Iceland||155 miles|
|Hurt 100||Honolulu Hawaii||100 miles|
|Badwater 135||California||135 miles|
|Barkley||Morgan County, Tennessee.||100 miles|
|Moab 240||Moab, Utah||240 miles|

What is the Longest Ultramarathon Distance?
The longest ultramarathon distance ever sanctioned is the Sri Chinmoy Self-Transcendence 3,100. It’s a multi-day 3,100-mile race that needs to be completed in 52 days. Runners are allowed to run from 6 am to 12 am.
It was founded by Sri Chinmoy and began as a 1,000-mile race in 1985. Chinmoy’s goal in creating the race was to give the participants an opportunity to discover their limits. In 1997, Chinmoy decided to increase the distance to 3,100 miles to allow the participants to truly reach self-transcendence.
The race takes place in one city block in Queens, New York where the runners have to complete 5,649 laps while the streets are in normal use.
How Long Can a Human Run Continuously?
The farthest distance run by a man without stopping is 350 miles. It took Dean Karnazes 80 hours and 44 minutes without sleep to complete such a feat.
Dean Karnazes is also famous for running a marathon in each of the 50 states in 50 consecutive days. He is the author of the book Ultramarathon Man: Confessions of an All-Night Runner which gives the general public an insight into ultra running.
