Where Australia Day Coastal Half Marathon starts and finishes
Australia Day Coastal Half Marathon starts at Semaphore South. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on.
Full Australia Day Coastal Half Marathon Route Breakdown
The Australia Day Coastal race starts at the Semaphore South foreshore, following the paved coastal promenade that hugs the Gulf St Vincent shoreline. Runners enjoy uninterrupted sea views and the historic Semaphore Jetty as the route winds along the beach. All distances share the same start/finish area, with the 5km staying close to the promenade, the 10km and 15km extending further north before looping back, and the half‑marathon adding an inland stretch before returning to the coast. The course is flat, well‑marked and suitable for walkers and families, offering a festive atmosphere with music and community support.

Training Strategy for Australia Day Coastal Half Marathon
10-14 weeks is a solid window for a first half marathon; 8-10 weeks is enough if you're already maintaining a baseline mileage. Build your long run up gradually rather than jumping straight to race distance.
This is a largely flat course, so most of your long runs can mirror that — flat and steady, building time on feet rather than hill strength.
Reduce overall mileage across the final 7-10 days while preserving short race-pace bursts. Arrive at Semaphore South fresh, energized, and primed — not fit, fresh.
Lock in your target pace using the interactive splits calculator below — no official pacers are confirmed for this event, so a pace band on your watch is the more reliable option.
Test your race-day fuel and hydration plan on your long training runs, not for the first time on race day — check the Race Day Checklist below for what's actually on this course.
Half Marathon Nutrition & Fueling Plan
A normal diet is fine. There is no need to carb-load for a race of this length.
Eat a carbohydrate-focused breakfast two to three hours before the start, and stick to something you've already tested in training rather than trying anything new.
Fluid at the on-course stations is usually enough; some runners take a single gel around the hour mark.
A mix of carbohydrate and protein in the hour or so after finishing supports recovery.
