After holding a small Formula One race on the Jarama circuit at the end of last season, the Royal Automobile Club of Spain, and ODACISA the circuit owners, organised the Spanish Grand Prix to be the first European round in the 1968 World Championship series and received support front all the teams except AAR-Eagle.
After some complaints from the drivers’ union about the rubber cones marking the edge of the corners, the loose gravel on the inside of the corners and the height of various guard-rails, a lot of last-minute work put everything right.
All the inside edges were surfaced with tarmac and the line of the corners was marked by bevelled kerbstones neatly fitted into the surface. These stones had radial flutes on them and caused no problems if a wheel ran up them, but there was little grip to be obtained from the fluted surface so there was no encouragement for drivers to run up them except in emergency.
