Seaside Coastal 2026 - RUN YELLOW

Seaside Coastal 2026 is the 11th running of a coastal road and path event at Semaphore South Foreshore, Esplanade, Semaphore South SA, Australia. The course runs along the coastal bike and walk path and uses an AIMS measured 10.55 km loop. The start and finish are positioned mid-loop so participants are generally no more than about 5 km from the aid station.

Distances offered on the day:

  • 5 km
  • 10 km
  • 21.1 km (half marathon)

All distance entries include a race bib and a finisher medal. The event has a yellow theme; a trophy is awarded to the person judged to best represent that theme and participants are encouraged to wear yellow socks.

A virtual option is available for all distances and must be completed on the event day at a location chosen by the participant. Virtual entries include a race bib and finisher medal that must be collected in person. Virtual results require a Strava link or similar showing elapsed or total time and submission of that link or a screenshot for inclusion in published results. Part proceeds are donated to the Australian Cancer Research Foundation to support cancer research. Visit the organization's website for the most recent information.
