Actually he never finished the run as he dumped his load of spice when the imperial ship chased him. So he didn't do the run and why jabba put the bounty on his head. Even though it was jabba that informed the imperials of the shipment.
If i remember Lucas was asked why he used parsecs and he said because it sounded cool to say.
Definitely was NOT jabba that turned him in.
And he completed the actual 'kessel run' before he dumped the spice
