Leigh-on-Sea Running Festival 2026

Discover the inaugural LOS Run Fest, an exhilarating running festival set against the backdrop of Leigh-on-Sea. This brand-new event offers runners three distinct distances: 5K, 10K, and Half Marathon, each designed to cater to different levels of experience and ambition.
The LOS Run Fest promises a unique race-day atmosphere with stunning coastal views that will inspire even the most seasoned athletes. While sharing some sections with the established Leigh-on-Sea 10K Classic, the majority of the routes are entirely new, providing runners with fresh scenery and challenges.
For those just starting their running journey or looking for an accessible challenge, the 5K distance is ideal. It's a perfect introduction to racing, suitable for juniors (minimum age based on event rules), parkrunners, and anyone seeking a fun yet achievable goal.
The 10K route offers runners a predominantly new course that winds through Leigh-on-Sea’s picturesque landscapes. Designed to be fast and scenic, this distance is ideal for those aiming for personal bests or simply enjoying the day's festivities.
For serious runners looking to push their limits, the Half Marathon presents an extended coastal adventure showcasing even more of Leigh-on-Sea’s beauty. This longer route caters equally well to first-time half marathon participants as it does to experienced athletes seeking a new challenge.
Every participant receives a bespoke finisher medal and chip timing for accurate results. The event also features live music, an engaging village atmosphere, and professional photography services capturing your race-day moments.
To ensure smooth registration on the day of the event, runners are encouraged to collect their bibs in advance during designated pre-race collection times. For those unable to attend these sessions due to travel or other commitments, alternative arrangements can be made for race-day pick-up by prior arrangement.
Stay tuned for detailed course maps and final instructions that will be emailed out a week before the event date. Join us at LOS Run Fest for an unforgettable day of running in Leigh-on-Sea.
Explore the unique blend of scenic beauty and competitive spirit, making every step along these new routes memorable.
