City-Bay Fun Run

About the Event

The City-Bay Fun Run returns to Adelaide, South Australia on September 20th, offering a diverse range of distances from the half marathon down to the carer run and wheelchair events.
Adelaide's coastal climate sets an invigorating tone for race morning. The event kicks off at 7 am with temperatures averaging around 14°C, feeling quite comfortable despite occasional breezes that can make it feel slightly cooler than expected due to humidity levels of about 68%. The start line is located in the heart of West Beach Park, surrounded by lush greenery and coastal views. Runners will enjoy a flat course along the beachside pathways before turning inland for some gentle undulations.
This race has been running strong since its inception ten years ago, with thousands participating each year to support local charities. The 2026 City-Bay Fun Run marks its eleventh edition, continuing as one of Adelaide's most popular community events that brings together residents and visitors alike under the banner of inclusivity and sportsmanship.
The course venue offers a mix of smooth asphalt paths along the beachfront and paved roads inland. Participants can choose from multiple distances including 12km runs for adults and wheelchair participants, 6km options suitable for all abilities, plus shorter 3km events designed to cater to beginners or those looking for an easier challenge. The half marathon is also available with its own unique challenges.
The start line at West Beach Park will see runners face a modest elevation gain of around 10 meters before the race reaches its finish at the same location. Alongside aid stations and hydration points, there are no significant special features on this course but runners can expect to stay well hydrated and fueled throughout their run.
Weather conditions on September 20th predict an average temperature range from a minimum of 10°C to a maximum of 18°C with the forecasted wind speed averaging at around 13.3 km/h, which is generally comfortable for most runners but can make running slightly more challenging due to its cooling effect.
