Course breakdown

The marathon (42.2 km)

The marathon is an out-and-back course consisting of two laps through the vineyards of Tanunda, starting and finishing at The Rex Aquatic Centre on Magnolia Road. The half marathon follows the same route but completes just one lap.

The flat, scenic course passes many prestigious wineries. One source mentions 314 m of total elevation gain with a maximum altitude of 301 m, but the profile remains highly accessible overall. The course winds through Barossa's wine country, offering stunning landscapes.

Aid stations and logistics for marathon runners

Seven aid stations are positioned along the marathon course, alternating water and INFINIT electrolyte drink: DS1 (2.9 km / 24 km), DS2 (5.9 km / 27 km), DS3 (9.3 km / 30.4 km), DS4 (12.3 km / 33.4 km), DS5 (14.4 km / 35.5 km), DS6 (18.6 km / 39.7 km), and DS7 (21 km). Marathoners have access to special drink drop options and pacers for various finish times.

Half marathon, 10 km and 5 km

Start times are staggered: 5 km and 10 km at 9:30 AM, half marathon at 10:00 AM, and marathon at 11:00 AM. The 10 km and 5 km follow portions of the same out-and-back route. All three shorter distances let you enjoy the vineyards without the demands of a full marathon.

What weather to expect

Typical conditions in late August in Tanunda show average minimum temperatures around 7.5°C and maximum temperatures of 15.4°C. There's approximately a 49% chance of notable rain, with an average of 2.2 mm of precipitation per day. Average wind speeds reach 22.1 km/h.

These cool temperatures are ideal for marathon performance. Plan for light clothing with a starting layer that you can leave at bag drop. If clouds move in, a light wind-resistant jacket can be useful. Hydrate regularly from the start, even if the cool air reduces your sense of thirst.

Race strategy and tips

Manage your pace on a fast course

The flat profile tempts you to start too fast. The layout is perfect for targeting a personal best, but stick to a conservative starting strategy. On the marathon, the two-lap format gives you a chance to learn the terrain on your first pass. Save energy to accelerate after kilometer 30.

Take advantage of AIMS certification

The course is measured and certified to AIMS and IAAF standards, allowing you to qualify for international marathons, including the prestigious Boston Marathon. If you're chasing a qualifying time, respect your pace plan and don't let race-day excitement ruin your final time.

Anticipate winds and changing conditions

With average winds of 22.1 km/h, the out-and-back course can expose you to headwind sections. During the marathon's second lap, you'll already know which sections are exposed. Adapt your effort: slow slightly into the wind, recover in sheltered portions near the vineyards.

Nutrition and hydration

Marathoners can drop personal bottles at six stations. Take advantage of this option if you have specific nutritional needs. For the half and 10 km, the regular water and electrolyte aid stations are usually sufficient. Test your nutrition plan during training.

What makes this race special

Bib collection takes place on Friday, August 21 from 12:00 PM to 5:30 PM at RunDNA in Hindmarsh, Saturday, August 22 from 12:00 PM to 4:00 PM at Château Tanunda, and Sunday, August 23 from 6:00 AM to 8:30 AM at The Rex Aquatic Centre. No late race-day registration.

The race village near The Rex Aquatic Centre features indoor bib pickup, gear drop, showers, and a café for post-race refreshments. The festive atmosphere includes live music and local food stalls, celebrating both sport and the region's wine culture.

This year, SARRC is providing a bus service to and from Adelaide to ease access and reduce parking congestion. A practical detail that transforms the experience.

Receiving encouragement during the Barossa Marathon Festival with Cobbr

When you start the marathon's second lap at kilometer 21, or pass the same vineyard for the second time, a morale boost can make all the difference. The Cobbr app lets your loved ones record voice messages that trigger automatically at the exact kilometer of their choice during your race. At kilometer 35, when fatigue sets in, hearing your partner's or children's voices will remind you why you're out there. These personalized messages work via your phone's GPS, without your loved ones needing to be physically present on the course.
