Following on from my route map for the World Solar Challenge – all 3,000 km or 1,900 miles of it – here are some personal route notes (revised from 2015). The graph below (click to zoom) shows approximate altitudes (calculated by overlaying the route on an altitude raster). The highest point on the route (about 730 m) is 20 km north of Alice Springs, although the steepest hill (Hayes Creek Hill, summit 203 m) is about 170 km from Darwin.
Darwin – Start

The city of Darwin marks the start of the race.
Katherine – 322 km – Control Stop 1

The town of Katherine (on the Katherine River) is a gateway to Nitmiluk National Park. It also serves the nearby Royal Australian Air Force base. The average maximum October temperature is 37.7°C.
Daly Waters – 588 km – Control Stop 2
The famous Daly Waters pub
Daly Waters is a small town with a famous pub. The Eindhoven team left a shirt there in 2015.
Dunmarra – 633 km

Dunmarra once served the Overland Telegraph Line. Today it is little more than a roadhouse, motel, and caravan park. In previous races, this was a control stop.
Tennant Creek – 988 km – Control Stop 3

Tennant Creek (population about 3,500) is a small town serving nearby mines, cattle stations, and tourist attractions.
Karlu Karlu / Devils Marbles Conservation Reserve

The 1,802 hectare Karlu Karlu / Devils Marbles Conservation Reserve lies along both sides of the Stuart Highway about 100 km south of Tennant Creek. It is home to a variety of reptiles and birds, including the fairy martin (Petrochelidon ariel) and the sand goanna (Varanus gouldii). Race participants, of course, don’t have time to look (unless, by chance, this is where they stop for the night).
Barrow Creek – 1,211 km – Control Stop 4

Barrow Creek once served the Overland Telegraph Line and nearby graziers, but is now nothing but a roadhouse. The Telegraph Station is preserved as a historical site.
Ti Tree – 1,300 km

Ti Tree is a small settlement north of Alice Springs. Much of the local area is owned by the Anmatyerre people. In previous races, this was a control stop.
Alice Springs – 1,496 km – Control Stop 5

Alice Springs is roughly the half-way point of the race.
Kulgera – 1,766 km – Control Stop 6

Kulgera is a tiny settlement 20 km from the NT / SA Border. The “pub” is Kulgera’s main feature.
NT / SA Border – 1,786 km

The sign at the Northern Territory / South Australia border shows Sturt’s Desert Pea (Swainsona formosa), the floral emblem of the state of South Australia.
Coober Pedy – 2,178 km – Control Stop 7

The town of Coober Pedy is a major centre for opal mining. Because of the intense desert heat, many residents live underground.
Glendambo – 2,432 km – Control Stop 8

Glendambo is another small outback settlement.
Port Augusta – 2,719 km – Control Stop 9

At Port Augusta, the highway reaches the Spencer Gulf. From this point, traffic becomes much heavier, which makes life more difficult for the drivers in the race.
Adelaide – Finish

Adelaide, the “City of Churches,” is the end of the race. The official finish line marks 3,022 km from Darwin.
