We used a good vacumn, a walmart baggie and small pulling tape for distances over 200'. CO2 years ago.

How long are the runs? We would typcially suck in a drag line with a shop vac but with set screw couplings there is quite a bit of air loss when compared to compression fittings. 1/4" steel fish tapes can go pretty far probably 150' if there aren't too many bends. We would often use two fish tapes feeding them from both ends of the run. Tie a wade of drag line on the nose of one and use a hook and the other the grab the wad inside of the raceway.

Lube up the fish tape. Get a new one if it's been abused.
Don't use one of those flexible fish tapes that look like a spring. May work for short runs but otherwise a POS.

Tie a string to a 1/2 and slide it thru as you assemble the next piece. Or even a rope.

shop vac, pull string, and walmart sack. with set screw couplings, you might have to tape up the joints, to get line to suck through.

That’s why I want to come up with a game plan before we run the conduits. You can spend a lifetime getting a string through a conduit in a bad scenario.

I would use a 10 ft push rod, could clip it or simply whiz it thru the next piece as you went. It will end up at the last piece the same time you do.

Leaf blowers typically will push them better than exhaust port on many shop vac's will.
Greenlee blower has a lot more push than many vacuum/blowers have, but it is a multistage blower where the typical shop vacuums are usually just a single stage blower.
