Me and my old boss tried something similar years ago. Same ducting and cable size. Duct about 80metres long with a slight dogleg at one end. We had to tie the rope to the back of my van as pulling it by hand was impossible. Managed to get it 80% of the way but the rope snapped when the SWA reached the dogleg. we dug a hole found the break and managed to finish the job but to be honest I'd never wanna do it again.
