Targa Rallying

Targa rallying is a real test of driver and navigator; the driver needs to tackle the test/course as quickly as possible but they cannot do it without the navigator who tells them where to go.

Targa rallying may not be one of the most well known forms of rallying, but using standard cars and a cheap entry level of motor sport, they are rapidly becoming more popular. They are easily accessible to anyone with a road car and driving licence.

How does Targa Rallying work?

A targa rally comprises of a driver, navigator and a car. A targa rally is a long test/course, normally taking a few minutes per test to complete, defined by cones or pylons. The crew are provided with test diagrams which show where to go and which side of the cones to pass, and the navigator tells the driver where to go. Sounds easy? The crew need to ensure they go the right way, the driver cannot hit any cones for that will incur a time penalty and this all has to be done as quickly as possible. It’s a real test of driver skill, navigator skill, communication and team work.

The winning crew is the crew who completes all of the tests in the lowest aggregate time. Targa rallies can take place on tarmac or loose surfaces such as gravel or fields and normally take place at a single venue over one day.
