About the event
Great South Run – Mini, Junior & 5K
The Great South Run weekend isn’t just about the iconic 10-mile race – there’s something for everyone. The Mini and Junior Great South Run give younger athletes the chance to experience the buzz of a major running event in a fun, supportive atmosphere. Distances are age-appropriate, and every runner gets the thrill of crossing the same finish line as the elite athletes.
For those not quite ready for 10 miles, the Great South 5K is a fantastic opportunity to be part of the action. The flat, scenic course is perfect for beginners taking on their first event, as well as experienced runners chasing a fast time.
Together, these races make the Great South Run weekend a true celebration of running – whether you’re cheering on the kids, stepping up to 5K, or soaking in the energy of Portsmouth’s biggest sporting event.
