Officially these are not part of the main runways, which begin with the pedestrian crossing type markings immediately before the marked runway numbers.
If you re-read the AIP, you will see that's not the case.
It shows the length of the two
runways as 3902m (09L/27R) and 3660m (09R/27L), as measured from the point where the curved taxiways enter the two runways (the lines of reds on the aerodrome chart) at the 09 ends.
Those values are also the declared TORAs (takeoff run available) in the 09 direction. As has already been noted, the displaced thresholds of just over 300m mean that the LDAs (landing distance available) is correspondingly less on the 09s.
Incidentally the 27R TORA and LDA are both 18m short of the declared runway length - anybody know why ?
