The racing line is the path through a corner that lets you carry the most speed. You start wide, touch the inside at the apex, and let the car run wide again on the way out.
In short: Outside, inside, outside. That makes the corner as straight as possible, so you can brake later and use the power sooner. For most corners, a slightly late apex is faster and safer than an early one, because it lets you see the exit and accelerate in a straight line.
Key facts
- The racing line is the fastest path through a corner: wide entry, apex at the inside, wide exit.
- The apex is the point where the car is closest to the inside edge.
- A late apex means reaching the inside after the middle of the corner. It gives a straighter, faster exit.
- Exit speed matters most before a long straight, because that speed is carried all the way down it.
- At Stratos, a professional coach teaches the line from the seat beside you, corner by corner.
Why the line is wide, tight, wide
A car can only turn so tightly at a given speed. The gentler the arc, the faster you can go. Using the whole width of the track, from the outside edge to the inside and back, turns a tight corner into a gentle arc.
The four points of every corner
| Point | What you do | What to look at |
|---|---|---|
| 1. Braking point | Brake hard, in a straight line | Your braking reference |
| 2. Turn-in | Ease off the brake and steer toward the inside | The apex |
| 3. Apex | Touch the inside; start to feed in the power | The exit |
| 4. Track-out | Unwind the steering and let the car run wide | The next corner |
Your eyes are always one point ahead of the car.
Early, middle or late apex
- Early apex: you reach the inside too soon. It feels fast on the way in, and then you run out of road on the way out. It is the most common beginner mistake.
- Geometric apex: the exact middle. The highest speed through the corner itself.
- Late apex: you reach the inside a little after the middle. You give up a little speed in, and gain a straighter, earlier exit. For most corners, this is the one to use.
Slow in, fast out
The time is on the way out, not on the way in. A driver who enters a little slower and gets back to full power earlier is faster all the way down the next straight. Beginners do the opposite: fast in, then wait.
When the line changes
- Before a long straight: take a later apex and prioritize the exit.
- After a long straight: the entry matters more; brake late, then be patient.
- Linked corners: sacrifice the first to be right for the last, because the last one leads onto the straight.
- Hairpins: a very late apex, almost a U-turn, then straight out.
- In the rain: the usual line is polished and slippery. Drivers often move off it to find grip.
How to find the line on a new circuit
- Walk it or sim it first. See where the track goes.
- Follow the rubber. The dark band on the asphalt is where cars have driven.
- Pick references. A curb for turn-in, a curb for the apex, a curb for the exit.
- Go slowly and use all the road. Width first, speed later.
- Change one thing per lap.
The mistakes everyone makes
- Turning in too early.
- Not using the full width on the way out.
- Looking at the corner you are in, not the one that is coming.
- Adding speed before the line is right.
How a coach teaches it
At a Stratos event you first ride as a passenger while your coach drives the line and names each point. Then you drive, and they call it: "brake, turn, apex, power, out to the curb." After the session you watch the video together and see how close you came. By day two, most of the lap is yours.

FAQ
What is the racing line?
The fastest path through a corner: wide on the way in, close to the inside at the apex, and wide on the way out.
Why do racing drivers use the whole track?
Using the full width makes the corner's arc gentler, which allows more speed.
What is a late apex?
Touching the inside of the corner after its midpoint, to get a straighter and faster exit.
Is the racing line the same for every car?
Mostly. Cars with more power favor later apexes, to use that power on the exit.
What does slow in, fast out mean?
Enter a corner a little slower so you can accelerate earlier and carry more speed down the next straight.
How do I learn the racing line on a circuit I have never driven?
Learn it on a simulator, use fixed references for each corner, and have a coach call it from the passenger seat.
Does the racing line change in the rain?
Often, yes. The normal line can be slippery, so drivers look for grip off it.
What is the most common racing line mistake?
Turning in too early, which forces you to slow down on the way out.
