LONDON — parkrun, the global free 5km running event, celebrated its millionth event on June 11 at Bushy Park in southwest London, marking two decades of fostering community through sport, according to parkrun’s official website. The milestone event, which included junior 2km runs, followed the original 2004 time trial organized by Paul Sinton-Hewitt, a Zimbabwe-born, South Africa-raised former club runner.
Origins of parkrun
The first parkrun event took place in October 2004 at Bushy Park, with 13 participants and five volunteers, as documented by parkrun’s history page. Sinton-Hewitt, who later detailed the journey in his 2024 book *One Small Step*, described the initial gathering as a “time trial for fellow club runners.” The event evolved into a weekly community activity, expanding across the UK before becoming a worldwide phenomenon.

Global Expansion and Participation
Today, parkrun operates in 23 countries with 2,800 events weekly, attracting approximately 250,000 participants each week, according to the organization’s 2024 annual report. Over 140 million individuals have completed at least one event since 2004, with more than 12 million registered users. The program includes junior runs, prison initiatives, and partnerships with 2,200 GP surgeries in the UK to promote mental health through physical activity.
Community Impact and Volunteer Network
More than 30,000 volunteers support parkrun events weekly, with post-race socializing a core component of the experience. The initiative has also partnered with 2,000 schools through its parkrun primary program, aiming to increase youth physical activity. In the UK, 25 prisons host parkrun events, engaging over 12,000 individuals in custody, as reported by parkrun’s 2023 impact study.
Sinton-Hewitt’s Reflections
Sinton-Hewitt, who will attend the millionth event, expressed astonishment at the movement’s scale. “Never in my wildest dreams did I imagine the first event here would be the first of one million,” he said in a statement. The founder emphasized the program’s focus on “being outdoors, being active, and being social,” noting that many participants credit parkrun with improving their mental and physical health.
The celebration coincides with parkrun’s “Thanks a Million” campaign, highlighting the event’s role in building “lives changed and communities built by people from all backgrounds,” as stated in a press release. The organization’s charity, parkrun UK, continues to distribute proceeds from Sinton-Hewitt’s book to support local initiatives.
