As per title, why do most race tracks run clockwise?



Anyone know why? It's not just a UK RHD thing, all over the world the majority are clockwise...

They run anti-clockwise in the southern hemisphere, don't know why.

The first purpose made track in the UK (Brooklands) was counter clockwise, speedway is CC as is short circuit dirt racing in the USA as was board racing. The old GP circuit at Aintree is CC

I know there are exceptions with other forms of racing but taking the F1 tracks for instance, the vast majority run clockwise, wondered if there was a reason?

Coz the gears are on the left so you could statistically find it easier to change. More RH bends than LH bends presumably.

Coz God made them clockwise??

You're British. It's anti-clockwise!

Except that most established tracks were laid out long ago, when bikes had right hand gear changes.

I'm fairly sure that's why speedway runs anti clockwise, because when it started they used modified roadbikes with gearboxes, so you could change gear and still have your left leg out.

In it's early days, before the GP loop was built, Brands ran anti clockwise and I went to a bike meeting there in the 80s, where they ran anti clockwise, just for the challenge.

Remember cars are going to be a big factor in a lot of tracks. Not sure on the specifics - can see being on the inside having advantages for various reasons, but then more of the world sits on the other side in two seaters.

Well, a lot of the first race tracks were clockwise and the trend tended to continue as far as I know.

Another reason why a lot of tracks are now built clockwise is due to the fact that even at low level racing (I.e. 125cc DD Karts and even worse superkarts) when you race a clockwise circuit you build up extra muscle on that side of your neck to cope with the G-Force experienced in the corners.

When you get to an anti-clockwise circuit, damn do you feel it. If you are in a car that can pull 2-3G or above (the karts and cars I raced could hit 4-5G) and you are used to clockwise circuits after a few races you will begin to feel the strains on your neck.

For example, if you watch F1 at Turkey, around halfway through the race and especially nearer the end you will see the drivers rest their head on the cockpit safety walls around some of the turns, especially Turn 8 as their muscles are suffering so much.

Maybe it's just an act of kindness? Laughing! After a full weekends racing a superkart around an anti-clockwise circuit my neck ached for days. More clockwise circuits! Thumbs Up!

Also, depending on the racing discipline, that can affect the direction of travel.

For example, NASCAR always runs anti-clockwise and one of the reasons for this is because the driver is sat in the left of the car. This means should he hit the barrier there is a lot of car to crush before the driver himself hits anything which means increased safety.

I guess it's just down to preference of the circuit designers these days.

They should make all circuits figure of 8, unless they are over 5 miles long. Razz

Indeed - always thought it made sense, if nothing else for the tyre wear.
Most big circuits seem to have at least one bridge anyway, so shouldn't be too hard to have it so there's a fairly safe overpass that's actual track.

Yup, all the tracks I design* are figure of 8.

*Draw when bored at work, with racing lines and contour lines. Yes, it's not sad to do this when you're in your 30's....

The Karts must be a hell of a lot faster, the bends a lot tighter and the corners banked a hell of a lot more than I remember to achieve 4-5G. Are you really sure about that?

Worth a read, the forces you are talking about are the sort that make people dizzy and pass out and when I say people I mean people who race champ cars so to a degree are used to it.

Positive.

I have data from my MyChron E-Box on the superkart showing I pulled a max of 4.6G laterally but admittedly was only a one-time thing. I'd say the average maximum is around ~3-4G.

They are pretty quick mind you, raced Division 1 Superkarts which put out around ~95bhp from 250cc 2T engines. Full aero bodywork etc. They are incredibly quick and hold overall lap records at some circuits.

I say it need re-calibrating. At 4.6G your total weight of around 215kg would be equal to 989KG trying to go sideways and a 250cc Superkart does not have enough downforce to maintain a corner under that G.

<edit>Unless of course the reading was due to hitting something and the massive deceleration or being hit<edit>

The Superkart website reckons they get close to, but don't quite pull 3g while cornering, so go figure...................
