A few days ago, Parkrun turned 20 years old. What started as a simple community gathering, launched by Paul Sinton-Hewitt on October 2nd, 2004, has grown into a global sports phenomenon with over 7 million registered participants. It began as a way for people to come together and socialise, and it’s evolved into so much more.

I’m an occasional Parkrunner myself, showing up every now and then to run the 5km loop at my local park. And I often wonder: what would all these people have been doing otherwise? Twenty years ago, at 9am on a Saturday, this park might’ve had a handful of runners. Today, hundreds gather to run.

To me, Parkrun is a story of what happens when something unlocks the potential in a system, creating abundance where there was once scarcity. Where there were only a few runners, now there are many. Where people might have spent their Saturday mornings passively at home, now they’re out in the fresh air, moving, connecting, and engaging with their community.

What’s remarkable about Parkrun is that it’s powered by volunteers—ordinary people who freely give their time to make these events possible. This time and energy were always there, untapped, waiting for an outlet. Parkrun created that structure, unlocking this latent resource.

In many ways, this is the essence of regenerative design: seeing potential abundance in situations that seem scarce. Parkrun didn’t introduce new people or new resources into these communities; it simply provided a framework that allowed people to organize and engage. The potential was always there—it just needed to be brought to life.
