It is easier to just pull THHN/THWN through the conduit. The only time that you will see UF inside a conduit, is to protect it where it comes out of the ground, to enter a junction box on the side of the structure, or inside the structure.
There is no way to get three runs of UF through even a 1", no matter how hard you tried. The jacket is just that stiff.
