What Is the Racing Line in F1?

The racing line is the optimal path through a corner — or a sequence of corners — that allows a driver to carry the most speed while maintaining control. On a typical corner, the racing line involves braking in a straight line, turning in early towards the inside kerb (the apex), and then drifting out towards the outside of the exit. Following the racing line minimises the time spent on the slowest part of the corner. Going off the racing line onto the marbles or dirty track can cost grip and lap time.

Example: He’s defending by covering the inside line — the rival is going to have to try the outside or wait for another opportunity.
