Dame Kelly Holmes joins participants as the United Kingdom marks its one-millionth parkrun event. The landmark run takes place at Bushy Park in south-west London on Saturday morning, the same venue that hosted the very first parkrun more than 20 years ago. Several outlets report that the inaugural event was held in October 2004, when only 13 runners took part. The most recent event draws a mix of regular parkrun volunteers and runners commemorating the milestone alongside Holmes, a double Olympic champion and prominent figure in British distance running. The reports describe the one-millionth parkrun as a charity celebration tied to the broader parkrun community, using the historic location at Bushy Park to highlight the scale of growth since the event began. Overall, coverage focuses on the continuity between the first and millionth runs at the park, and the participation of Holmes in the anniversary event.
