A record number of people are pulling on trainers and heading out the door, and many of them are doing it in a crowd. The running boom of 2026 is powered less by lonely miles than by run clubs, group starts and a very social new culture. Here is what is behind it.
Head into almost any city park early on a weekend morning and you will notice something that was far rarer a few years ago. Not the odd solitary jogger, but whole packs of people, chatting and laughing as they run in loose formation, then piling into a nearby cafe afterward as if the run were merely the excuse for the coffee.
Running got its groove back
Running is having a genuine moment, and it looks nothing like the grim, solo slog of old. The sport has reinvented itself as something communal, sociable and, improbably, fashionable, drawing in a huge wave of newcomers who might never have laced up if it meant pounding the pavement alone.
What makes this revival striking is who is driving it. This is not just seasoned club athletes clocking their usual miles, but a young, plugged in crowd who treat a group run as part workout, part social occasion and part content for their feeds. The result is a boom that feels less like a fitness fad and more like a cultural shift.
The numbers behind the surge
The scale is easy to underestimate until you see the figures. According to data from the research firm GWI, the estimated number of people around the world who run or jog climbed from roughly six hundred and seventy two million in 2022 to nearly seven hundred and eighty five million by 2025, adding well over a hundred million runners in just three years.
The youth surge is even sharper. The same research suggests the number of Gen Z runners jumped from about one hundred and eighty six million to two hundred and fifty nine million over the same stretch. Demand for the big races has followed suit, with the 2026 London Marathon reportedly drawing more than one point one million ballot applications.
The rise of the run club
At the heart of the whole phenomenon is the run club. These are informal groups, often organised through an app or a social account, that meet at a set time and place for a shared run at a friendly pace. No membership card, no intimidating times, just an open invitation to turn up and move together.
Their growth has been explosive. Strava, the fitness tracking platform that has become the sport's unofficial social network, reported in its 2025 Year in Sport review that the number of running clubs on its service grew more than threefold in a single year, while events organised by those clubs rose by around half.
Why the timing is perfect
It is no accident that this took off when it did. In the years after the pandemic, a lot of people found themselves craving real world connection and cheaper, simpler ways to find it. Running asks for almost nothing, a pair of shoes and a stretch of pavement, and a run club adds the one ingredient a gym rarely does, built in company.
Social media poured fuel on the fire. Runs are no longer just completed, they are logged, mapped and posted, turning every outing into something to share. Analysts have tracked a sharp rise in mentions of fitness apps online in recent years, a sign of how thoroughly the humble jog has migrated onto our screens as well as our streets.
More than just a workout
Ask regulars why they keep showing up and the answer is rarely about pace or distance. It is about the people. Run clubs have quietly become a place to make friends in a new city, to find a bit of structure in a chaotic week, and increasingly even a place to meet a partner, filling a social role that pubs and clubs once held.
The mental side matters too. Many runners describe the group start as the thing that gets them out of bed on a grey morning, the gentle accountability of knowing others are waiting. The physical benefits are almost a bonus, tucked in behind the sense of belonging that keeps people coming back week after week.
How to join the pack
Getting started is refreshingly low stakes. A quick search on social media for a run club in your area will usually turn up several, often sorted by pace so nobody gets left behind. The golden rule is to swallow your pride and start with the slowest group, where a walk break is not just tolerated but expected.
Beyond that, keep it simple. Comfortable shoes matter more than fancy ones, build your distance up gradually to keep injuries at bay, and remember that the point is to enjoy it. If you finish your first outing already looking forward to the next, you have understood exactly why so many people are suddenly running.
For all the apps and hashtags, what is really happening here is old and simple. People are moving their bodies and doing it together, swapping screens and isolation for fresh air and company. Of all the trends to sweep through in recent years, a boom built on friendship and a good pair of trainers is a hard one to argue with.
