Course Details

Elevation profile
The Running Company Half Marathon course is flat with just 105m elevation change over 21.1 kilometres.

Course Description
Starting on the beach, runners will run south to the turnaround point just before Sellicks Beach ramp before returning to the Aldinga Bay Surf Life Saving Club. This beach section is run on hard packed sand and is approximately 4 kilometres long.

You will leave the beach up the vehicle ramp at Aldinga Bay SLSC past water station 1 and run west along Norman Road for 700m before turning left into Aldinga scrub. Follow the road & fire trail until you exit the scrub on to Cox Road. A 1 kilometre section of road will take you past the Aldinga Beach Caravan Park and back into the Aldinga Scrub.

Follow the fire trail for about 1.5 kilometres with scrub on your left and vineyards on your right with the Mount Lofty Ranges rising up in the distance. Water station 2 is located at the exit from the scrub. The path then winds through the Aldinga Wetlands before following a bitumen path between the Aldinga Scrub and Sundays housing estate. At the end of this path you will be sent left down Dover Street then right down Fraser Street, right onto Maurice Street and left down Morgan Street. Keep left and inside the witches’ hats along this section of quiet suburban streets.

A controlled crossing will take you across the Aldinga Esplanade where you turn right to follow an out and back section to the Star of Greece at Port Willunga. Water station 3 is located at Snapper Point and is accessible as you run past it in both directions. When you return to the Aldinga Beach Boat Ramp you will rejoin the beach for the final 2 kilometres along the beach and up the vehicle ramp to glory at the finish line.

Drink Stations

Water stations on The Running Company Half Marathon course will be located at Aldinga Bay Surf Life Saving Club (4KM), exit from the Aldinga Scrub (9KM) & Snapper Point (13KM& 17KM).

Lemon Lime Nuun Hydration sports drink will be available at both Snapper Point drink stations and at the finish line.

We do not expect it to be too warm in May so please drink to thirst & be careful not to over-hydrate.

Only compostable cups made from plant-based materials will be used during the Great Southern Half Marathon to minimize our impact on the environment. Please try to hit the bins provided at the water stations and be aware that littering on the course will result in disqualification. Runners may also carry their own drink bottle or cup to refill at water stations.


Toilets can be found on course at Sellicks Boat Ramp, Aldinga Bay Surf Life Saving Club, Hart Road, Snapper Point and Aldinga Boat Ramp

Cut Off Time

The Running Company Half Marathon is open to both runners and walkers and the course will be progressively closed at a pace of 8:30 per kilometre (equivalent to a finish time of 3 hours).

A tail walker will follow the last participant around the course for safety reasons and to relieve marshals from their positions. If you fail to maintain the minimum pace you will be asked to stop and return to the start finish area. This is the last thing we want to do on race day so if you are not confident that you can complete the half marathon in this time please enter the 10K event.


Please be courteous to our marshals and other volunteers. Remember that they are giving up their Sunday morning to make sure that you will enjoy your run.


Traffic Management

Much of The Running Company Half Marathon course is run off-road. There will be two road crossings of the Esplanade controlled by accredited traffic managers.

Sections of the course are run on quiet back roads that remain open to traffic. There are no road junctions for you to negotiate but you must be vigilant for vehicles coming on or off of driveways. Always follow the instructions of course marshals, run within cones and follow the road rules.

Silver Sands beach will be open to cars on race day and has a 10 KM/H speed limit (though you may run faster if you like!). Minimal traffic is expected on the beach in May but you should remain aware of any vehicles around you.


Trophies will be awarded to the first 3 males and first 3 females place-getters in The Running Company Half Marathon. Presentations will be made at the finish line as soon as the top 3 runners have finished.
