Carrera Sudamericana is the latest creation of Trans World Events.
It is a 21-day marathon rally in May 2006 run on a daunting route over the Andes taking in Argentina, Bolivia, Peru and Ecuador.
It starts in Buenos Aires and follows the route of the famous Fangio road races, the Gran Premios, of the 1940s and 50s.
Event Director Nick Brittan, just returned from a survey trip promises, "This is not one for the faint hearted, we'll be up above the tree line at 15,000 feet over the roof of Andes in Bolivia and Peru.
We'll be running special stages at heights private plane normally fly at.
But the upside is that there will be rest days giving time to visit the lost city of the Incas at Machu Picchu in Peru and time to spend in La Paz the world's highest capital city in Bolivia," said Brittan.
On the lighter side Brittan also promises competitors the opportunity to learn to tango in the famous street tango cafes at sea level in Buenos Aires.
The route covers over 8,000 km through the four countries with special stages on a mix of demanding gravel and tarmac roads. Cars eligible in the rally are TWE's tried and tested pre-1978 classics and modern up to 2-litre showroom cars (no turbos and no 4wd).
The Clowes Cup Regularity category (no competition license required) also takes classics up to 1977, recreational 4wds and other suitable vehicles.
Basically the same format as TWE's recent successful London-Sydney Marathon.
