I have pictures how did they did it. There is no pull boxes between.
Except from being "glued" together at two places using insulating
tape, it is one tube from one end to the other. So at least air
should go from one end to the other.

Be careful pulling on CAT5 you don't want to break what you have. You
may be right that they installed the wire as they went along and do
have too many bends in the raceway. Are you sure they don't have some
pull boxes in between? The other thing you can try is to suck some
pulling lube in there with a vacuum cleaner. Home stores and
electrical suppliers have it. Don't use oil. If you do get it to pull
air all the way through, end to end, try sucking a stout piece of
nylon string through. 2 or 3mm . Use that to pull in another cable.
