Why the Whole World Is Suddenly Running: Inside the Global Running Boom

Look around almost any city at dawn or dusk and you will notice it: more people than ever are out running. What was once the solitary pursuit of the dedicated few has swelled into a genuine global movement, filling parks, pavements and starting lines around the world. Running, one of the simplest and cheapest forms of exercise, is enjoying a boom so large that it is reshaping the sporting landscape and the fitness industry alike.

A world on the run

The scale of this surge becomes clear the moment you look at the raw participation numbers. According to reports, the number of people who say they run or jog rose from around 672 million in 2022 to nearly 785 million in 2025, an astonishing increase of more than 110 million people in just three years. It is a wave that shows little sign of slowing down anytime soon.

Interestingly, the motivation behind this new generation of runners has shifted in a meaningful way. According to reports, nearly a third of all runners took up the sport during the pandemic years, and many of them were drawn not by competition but by a simple desire to look after their health. For these newcomers, running is less about winning races and more about wellbeing and routine.

Marathons hit record demand

Nowhere is the boom more visible than in the frenzy surrounding the world's great city marathons. According to reports, the 2026 London Marathon received more than 1.1 million ballot applications, setting a new global record for any marathon. The 2026 Sydney Marathon saw its applications jump by 56 percent on the previous year, while the 2024 New York City Marathon produced the largest field ever with 55,646 finishers.

Beyond the marquee events, participation in road races of all distances has climbed sharply. According to reports, the number of road race finishers worldwide rose by 17.1 percent in 2024 to reach around 4.67 million people across some 600 races in 44 countries. Marathon finishers specifically grew by 14.6 percent to just over 1.14 million, spread across the many races that were surveyed.

The Gen Z wave

A huge part of this energy is being supplied by the youngest generation of runners. According to reports, the number of Gen Z runners jumped from 186 million in 2022 to 259 million in 2025, adding more than 70 million young participants in the space of just three years. This influx of youthful enthusiasm has given the sport a fresh and distinctly modern character.

For many of these younger runners, the appeal lies as much in connection as in fitness itself. According to reports, some 77 percent of Gen Z athletes say they feel more connected when they see their friends' activities shared online, and this generation is markedly more likely than older ones to view sport as a way to meet like-minded people. Running, it turns out, has become a powerful social glue.

Running goes social

This social dimension is transforming how the sport is actually practised day to day. According to reports from the fitness platform Strava, the number of activities posted on the app soared from around 1 billion in 2017 to some 4 billion in 2025. Even more strikingly, the number of running clubs on the platform grew three and a half times in 2025 alone, while club-organised events rose by around 50 percent.

The buzz has spilled far beyond dedicated fitness apps and into mainstream social media. According to reports, mentions of Strava on Instagram increased by more than 70 percent between January 2023 and January 2026, as run clubs became fashionable community hubs. For many, joining a weekly group run has become a genuine alternative to a night out, blending exercise with friendship.

This craving for real world community is now one of the strongest engines behind the boom. According to reports, around 37 percent of people say they view running clubs as a great way to make new connections, turning a simple jog into a chance to build friendships. In an age of screens and isolation, the weekly group run offers something increasingly rare, namely genuine face to face belonging.

A booming business

Where crowds gather, commerce inevitably follows, and running has become very big business indeed. According to reports, the global running apparel market is projected to expand past 112 billion dollars, fuelled by younger buyers, premium gear and the crossover of athletic wear into everyday fashion. The wider endurance sports event market, meanwhile, was worth around 11.2 billion dollars in 2024 and is expected to keep growing steadily.

In the end, the great running boom is a heartening story about people rediscovering something wonderfully simple. All it truly takes is a pair of shoes and the will to step out the door, yet the rewards, in health, community and personal achievement, are enormous. Whether chasing a marathon medal or simply a clearer head, millions have found in running a habit worth keeping for life.
