Ultramarathons—races longer than the traditional 26.2 miles (42.195 km)—have surged in popularity in recent years, but they still represent a small fraction of the global population. Despite the growth in ultra-running participation, how many people worldwide are actually taking on these grueling endurance events? Let’s dive into the numbers and look at global participation rates, breaking it down by region and per capita to understand the true scale of this growing sport.
Global Participation: Less Than 0.01% of the World’s Population
In 2023, the International Association of Ultra Runners (IAU) reported that approximately 140,000 ultra marathon finishers worldwide, including races ranging from 50 km to over 200 miles. With a global population of about 8 billion, this means that only around 0.002% of the population participates in ultramarathons each year. To put that into perspective, this is equivalent to 1 in 57,000 people running an ultra marathon globally.

United States: Leading Ultra-Running Participation
The U.S. remains the largest contributor to the ultra-running scene. According to Ultrarunning Magazine, 80,000 finishers took part in ultra marathons in the U.S. in 2023. With a population of 335 million, this translates to around 0.024% of Americans running an ultra marathon each year, or approximately 1 in 4,000 people.

Europe: Growing Popularity but Still Niche
Europe is also seeing an increase in ultra-running participation, with countries like France, the United Kingdom, and Spain leading the way. Europe’s total number of ultra marathon finishers is around 50,000 annually, with France accounting for a large portion. With a population of approximately 748 million, this puts Europe’s participation rate at about 0.0067% of the population—still a niche but growing segment.

Asia: Ultra Running on the Rise, But Small Scale
In Asia, the ultra marathon scene is relatively young but growing, especially in countries like Japan, China, and India. The participation rates in Asia are still very low compared to Western countries, though there are signs of significant growth.
• India, with its population of over 1.4 billion, reports fewer than 10,000 ultra marathon finishers annually, translating to just 0.0007% of the population. Despite the low participation rate, ultra marathons in India are gaining popularity, particularly in cities like Bengaluru, Delhi, and Pune.

• China, with a population of 1.4 billion, also has a small but growing ultra-running community. While precise figures are harder to come by, estimates suggest that fewer than 20,000 ultra runners finish races annually, putting the participation rate at around 0.0014% of the population.

• Japan stands out in Asia as one of the most established ultra-running countries. With a population of around 125 million, Japan sees an estimated 20,000 ultra marathon finishers annually, yielding a participation rate of about 0.016%.

Per Capita: Participation Rates by Country
When you break it down per capita (per 100,000 people), the U.S. leads with about 24 ultra marathon finishers per 100,000 people. In contrast, countries like India and China have significantly lower rates, with fewer than 1 ultra runner per 100,000 people. Here’s a look at some key figures:
• United States: 24 finishers per 100,000 people.
• France: 7 finishers per 100,000 people.
• United Kingdom: 6 finishers per 100,000 people.
• Japan: 16 finishers per 100,000 people.
• India: 0.7 finishers per 100,000 people.
• China: 1.4 finishers per 100,000 people.

The Growth of Ultra Running
While ultra running is still a small percentage of the global population, its popularity is rapidly growing. Over the last decade, the number of ultra marathon events worldwide has increased by more than 50%, according to Statista. Much of this growth can be attributed to the rise of trail running, which has made ultra races more accessible and attractive to a broader audience.
