Course elevation profile, 8× vertical exaggeration Elevation along the course from km 0 to km 21. The trace runs between 6 and 46 metres, a range of 40 metres, drawn at 8 times vertical exaggeration so the shape is legible. Smoothed over 1 km before this profile was derived. An unsmoothed urban surface carries the buildings and would assert a climb that is not there. The dashed stretches are bridge decks: Anzac Highway, km 8.4 to 8.4; Anzac Highway, km 12.8 to 12.8. A bare-earth model reads the ground or the water beneath a bridge, not the deck the runner is on, so those runs are interpolated between the ground either side rather than measured, and they under-report the real climb across a span.

Whole courseFinishGlenelg to the city and back to Colley TerraceStart and finish on Colley Terrace in Glenelg, 21.1 km.

Runners returned to Glenelg by Brighton Road or Gordon Street and then Jetty Road, where the organiser warns of the tram lines and the corner from Jetty Road onto Colley Terrace. The finish area leads on to the event village at Colley and Wigley Reserve. The half marathon is for adults only, and the 2026 race ran on 20 September.

The road starts at about 6 m beside the sea at Glenelg, sits near its lowest point early on and rises gently to the high point near the halfway mark. The way back is a gradual fall to the finish at Colley Terrace.

An invisible layer before the start keeps seams, straps and shoes from rubbing skin raw.

Put it on before you leave for the start: heels and toes, inner thighs, under a bra or heart-rate strap.

Try it on a long run first, like everything you use on race day.

One in a pocket cushions a blister if one starts.

Put it on clean, dry skin and leave it until it comes off by itself.
