Curiously, because the two carriageways do not run perfectly parallel on the northern section, the inner (anti-clockwise) carriageway is actually longer than the outer (clockwise) carriageway.
I came across this fact a few years ago when the company I worked for ran a charity event where they drove a car around the M25 for 24 hours, pausing only to refuel and change drivers every lap. - they ran it two consecutive years, but in opposite directions, and this fact came up in their discussions with the authorities (Police, Highways Agency, AA, operators of the South Mimms and Clackett Lane services).

average distance of M25 from centre of London is 20 miles.
20 miles = 35200 yards = mean radius of M25 "circle"
If you allow an extra 10 yards on the radius for the clockwise lanes then you would travel 110661.24 yards (circumference = diameter x pye).
If you subtract the 10 yards on the radius for the anticlockwise lanes then you would travel 110535.36 yards (circumference = diameter x pye)
If you subtract the distance of the anticlockwise from that of the clockwise distance you will see that on average the clockwise complete circuit is approx 188 yards longer than the anticlockwise circuit.
If you have to do a full circle go anticlockwise - you will save fuel
hope this helps

It should be but you would need to take into account other factors such as where the motorway carriageways part and come back together at numerous points as this could affect distances.
The official distance of one lap is 117 miles.
The only other fact I know is that the M25 is not a complete circle as it becomes an A road for the Dartford crossings.

Yes, if you go anti-clockwise you'd be on the inside of the "circle", so have less distance to go than if you were going clockwise.

anti clockwise is shorter if you were to do 1 whole lap of the M25 yes but only by say... a mile? not alot of difference

Yes, as clockwise is on the out side, there fore being longer.

Yes it is less, reason being , you are travelling on the inside of the
''circle'' when going anti-clockwise.
Hope this helps.

You need to learn to speak English before asking questions.
