Broad Run begins on Ball Ridge in Moreland Township. It flows south-southeast for a few tenths of a mile before turning south-southwest for several tenths of a mile, crossing Pennsylvania Route 118, and receiving an unnamed tributary from the right. The stream then turns south-southeast for several tenths of a mile, flowing through a valley, before receiving a very short unnamed tributary from the left and turning south-southwest. After a few tenths of a mile, it receives another unnamed tributary from the right, and several tenths of a mile further downstream, it turns west-southwest for a short distance and receives an unnamed tributary from the right before turning south-southwest and then west-southwest. After several tenths of a mile, the stream receives an unnamed tributary from the right and turns south-southwest for several tenths of a mile, reaching the end of its valley. It then turns west for a short distance before turning south and reaching its confluence with Little Muncy Creek.
