Yeah, you don't want to use a cable assembly in conduit. Normally, wiring before the meter is owned by the utility and not subject to NEC code but I don't know how it works in this case where you are supplying it. If you have to follow NEC code, they don't allow pulling the wire while piecing the conduit together. I think it has to do with the (not completely dried) glue damaging the insulation on the conductors and possibly they want to make sure that wires can be pulled (in a difficult run) in the future if need be.
IMO, piecing it together doesn't make it any easier because in the end you are still pulling just as hard as you would in a completed conduit unless you are feeding the conduit over your already layed wires. I would REALLY WORRY about the glue in this case. However, the added end sweep and pulling in a vertical direction is a bit of a pain if that is what you are doing. 110' through 2 1/2 should be a breeze if it's a fairly straight run. Use plenty of lube and ***a good strong pusher***. The pusher is very important for an easy pull.
