One of the toughest ultra-running race lists have been created by a scientific study which is decided using various criteria such as temperature, distance, elevation gain, energy expenditure, etc. A virtual running challenge brand, ‘Rokman’ has helped in supporting this research. These criteria have been rigorously researched and looked into before taking the final call. These have been then compiled to create the toughest ultra running races in the world. Here are some of the categories which are discussed under this race:

Expenditure

One of the key things which the individuals invest in apart from their physical and mental self, is the per race/trip energy expenditure. The researchers have looked at various races which had the criteria of calorie burn in it as well. There are races such as Tor de Geants, Moab 240, and Dragon’s Back race which have been listed as the top three races of all times, where individuals have burnt maximum amount of calories.

Distance

The Wild Horse 200(miles) takes place in Wales. It is known to be one of the non-stop races which have helped in creating the list. The six-day race (236 miles) in Wales, known as Dragon’s Back Race and the non-stop 240-mile Moab 240 are studied to understand the distance factor for the toughest ultra running race.

Temperature

There are top three races which have been researched according to the temperature criteria. These are the Badwater 135, Everest Marathon, and the Marathon des Sables.

Elevation

The second highest elevation is seen in Dragon’s Back Race which consists of a total of 17,400 meters. The Barkley Marathons is right after this race with a whooping 18,288 meters of ascent. It is also one of the tough courses where the runners have a tough time completing it.

Another notable race is Tor des Geants, a mountainous French race. This race name translates to the Tour of Giants. The runners run all throughout the course at a total ascent of 24,000 meters on a mountain top.

After a very rigorous process of research and study, it was then decided that calories burnt per miles was the most helpful criteria to come to a conclusion regarding the toughest race of them all.

Here are the 5 of the worlds toughest running races, which are mentioned below:

  1. The Barkley Marathons
  2. Pikes Peak Ascent and Marathon
  3. Ultra-Trail du Mont Blanc
  4. Badwater 135
  5. Tor de Geants

There are various races which are usually tough to finish. The above mentioned races is some of them. Theoretical study has been very insightful in understanding the nuances and then finding out the toughest race of them all.
