Dragging the rope in as you lay the ducting is the best method if the duct is sectional the compressed air method or a cobra rod is the way if it's a continuous duct.
Back fill the fill the trench before attempting to put the cable in otherwise it will be a night mare

Hmm.methinks I see a gadget idea for dragons den...
something with 3 or 4 spring loaded tracks and either a long cord for power or battery powered..
When the alternative is being able to tell the wife that this is actually an essential tool, not a toy?

Just for those who don't believe in hose pipes - done it lots of times, it works because the rag (or ball etc) is both lubricated and pushed slowly and it doesn't matter about it being straight or coiled - although it must be coiled 'downhill' or then you will get wet.
Submarines and ships are often wired using small animals, but I think they need an odour or light at the end.

A tried and tested method in the old days of the GPO for pulling draw wires along phoneline ducting.
Starve the animal overnight, smear the inside edge of the duct exit with its favourite food and feed the animal in at the other end with a thin draw cord tied to its collar/waist.
It does work!
I know its an old thread but I have just installed a 25mm concentric armoured cable into a 50mm duct and a 50pair comms cable & a 6 fibre cable into the other approx 120m long.
The redline in this: //media.diynot.com/125000_124249_41986_80215802_thumb.jpg indicates the Gas & Water pipes and Power & comms ducts as laid by the main contractor of a new building.
Henry hoover was used to get a thin string [brickies line] through first then 2 lengths of 8mm poly ropes [BT draw rope] used to pull the well lubed cables through.
It took an hour total for 2 of us to get the string and then ropes in and one to feed and 4 to pull the cables in, including unloading and setting up cable jacks etc.

That is the best way to do it.
Using light weight string a Henry type vacuum cleaner I pulled in over a 100 metres of cordage in about a minute, as fast as it could be feed in to the end of the duct it got sucked through.
this is why cobra rods are worth their weight in gold....
No picture. Can you use the method to show the pic in your post? See forum rules for details.
Yes but a 100metre Cobra is £300ish. Not worth it for one duct run.
Can be hired by the day though.
As good as Cobra rods are it was much quicker to employ henry, especially with the 6 bends on this duct.
Sorry long time since I've done this, hopefully this works & with a slightly better sketch
