perhaps it is the ground roll that needs explaining here rather than going into great discussions about clearways etc.
The actual landing roll on a 152 if flown to the correct speeds and not the 70kts that seem tobe taught by most instructors is actually very short indeed. The take off role is also short in a 152 again if flown correctly.
I own a 152 and over the last thousand or so hours have put it into a lot of very short strips. I look for the landing role distance available as being from the point the wheels touch the ground on t he way in and from the point the wheels leave the ground on the way out. On a normal day I can get in and out of 300m without breaking sweat.
The problem with most spamcam drivers is they fly the aircraft to fast, either through bad instruction or bad technique.
So here is a question, what is the safe approach speed for a 152 with full flap that will give the shortest landing distance?
Next what is the correct rotate speed that will get you cleanly of the runway in the shortest distance.
Lets compare notes.
