Semaphore South defines this run: flat coastal bike/walk paths, the ocean nearby, and that relaxed beach-suburb atmosphere before your legs are fully awake. The Western Coastal Running Festival marks the 11th year of a low-cost, low-key community event by Coastal Fun Runs. Part of the proceeds go to charity, and the event carries a "running with purpose" sentiment without being ostentatious. The course is a loop on paved coastal trails, measured by AIMS, with the start and finish in the center so the aid station is always accessible. Expect "uninterrupted ocean views," "refreshing sea breezes," and many opportunities to observe other runners and walkers on the out-and-back route. It attracts participants ranging from first-timers and casual walkers to experienced marathoners. The unique "WESTERN" themed trophy, chosen by attendees, is a notable quirk.

Semaphore South Foreshore hosts the start and finish on the coastal bike/walk path opposite South Terrace, with the Esplanade nearby. Seaside Coastal Run offers an "accessible and affordable coastal fun running event" feel, returning for its 11th year. Part proceeds support the Australian Cancer Research Foundation. The course is a "certified AIMS-measured" loop along the coast, designed so you are "never more than approximately 5 km from the aid station." Runners, joggers, and walkers will share the path, contributing to a "yellow-themed community atmosphere." Yellow socks are encouraged, and a trophy is awarded to the best representation of the theme.
