Course Layout / Marking
Lake Gairdner is a National Park, administered by the Department of Environmnent, Heritage and Aboriginal Affairs for the State of South Australia. Although the lake is some 80 miles long it is only that area south of the 32nd parallel that they have given permission for Land Speed Racing. Of this area the DLRA uses only a small portion, closest to the Mt. Ive Station, As this is the only "made road" to the lake.
The course will be defined as shown in the diagrams below. (This may vary slightly depending on surface conditions).
This includes the competition track(s), the pit area, spectator area, and access routes from the lake edge to the defined areas.
All areas and access routes will be clearly defined by suitable temporary signage, bunting or other approved methods to ensure all participants and spectators are aware of the approved locations for vehicles to be driven, parked and where foot traffic is permitted. Designated non-access areas will be clearly defined and signposted.
The Operational Plan describes the requirements to conduct the annual Speedweek held at Lake Gairdner in South Australia by the Dry Lake Racers Australia.
All motoring events have an element of public risk and potential for environmental impact. The Operational Plan has been compiled with due consideration to reduce these risks and to prescribe the tasks required to conduct a safe and enjoyable event for participants and spectators.
The DLRA offers 2 tracks for Speed Week. Both tracks are timed by the same state of the art TAG Heuer clocks and wireless data radios.
Track 2 is used for cars up to 150 mph and motorcycles up to 175 mph. It is also the track used by rookies for their first pass and for cars to do their 125 mph and 150 mph licencing passes and motorcycles to do their 125 mph, 150 mph and 175 mph licencing passes. There is only one timing trap it is between the 1 3/4 mile and 2 mile.
There are prescribed conventions for where a vehicle goes at the end of a run on Track 2. Vehicles on track 2 turn out to the left when they have completed their run and follow the return road back to the start. They must go past the clearance flags on the return road be fore the track is clear and the next competitor can run down the track. If a vehicle experiences difficulties on track 2 and requires the attention of the fire and rescue teams they turn out to the right.
Track 1 has 2 miles of run up, 3 timed miles and 3 miles of slow down. It is used by cars that travel faster than 150 mph and for motorcycles that travel faster than 175 mph. There are 2 courses on Track 1, the short course uses only the first mile of timed track. Vehicles traveling slower than 175 mph must use the short course, unless by prior arangement. Vehicles that travel faster than 175 mph are permitted to use the full 3 mile of timed track. There are timing traps between the 2 mile and 2 1/4 mile, the 2 mile and the 3 mile, the 3 mile and the 4 mile and the 4 mile and the 5 mile.

Course 2010 - 2014
The 2010 layout intorduced a second track for the first time and the removal of the Test 'n Tune Track. GPS units were used to determine a top speed on this 3 mile track. These speeds were not recognised for setting records and were only recorded to the first 2 decimals. It proved to be very popular for licensing runs but was usually closed by the Thursday as most competitors had moved to the main track to set recognised runs.
Course Layout 1990-2009
This was the track layout prior to going to the two track layout in 2010.
The track runs roughly South to North there is 3 miles of run up, 3 timed miles and then 3 marked miles for slowing down. The pits are located centrally between the track and the shore on the east side of the track. All the timing equipment and the van are on the west side of the track, away from any traffic.
