Cardio is fine once or twice on a bulk, any more is counterproductive.
Running post workout, would generally help deplete muscle glycogen, which should be replenished especially after a weight training session on a bulk. Steady cardio can shrink muscle fibers at a greater chance than an anaerobic activity will, so take that into consideration when choosing upon cardio types.
Any form of cardio pre-workout will a) deplete useful muscle glycogen, and, b) reduce power output on most exercises.
Eat enough to recover the calories burned from running and you should be fine. I don't perform any form of cardio on a bulk.
