Go to Career.

Select 'group 2' , the only group that you can select and finish all the races and stages. You do not need to win to unlock.

Difficulty and damage settings don't matter.

Select career.

Select group 2.

Group 2 consists of 5 years
1967 - 1 rally x 2 stages
1968 - 1 rally x 2 stages
1969 - 1 rally x 3 stages
1970 - 1 rally x 4 stages
1971 - 2 rallies x 4 stages

Routes and countries seem to be completely random.

You don’t have to win but seriously, who likes losing? To make it easier for you, you can set the difficulty to easy and damage level to none. This will not affect the achievement.
