In Lotro, tons of level 46-50 mobs, with many elites scattered among them. There are also elite drakes sleeping here and there that you should try to avoid if possible.
Since the mobs are pretty evenly spaced around the place, there are not a lot of places where you can lose aggro completely. If you are doing the running through method, your best bet is just to stop every now and then when you only have one or two mobs on you. Kill them and rest up.
Remember that you will not be able to avoid every mob. It is sometimes better to run straight through one mob and know you will aggro it than to run in between two mobs and hope you will aggro neither but end up getting both.
While on the south path, you can occasionally drop down to lose aggro. The path is so long that the mobs are almost always unable to find a way to get down to you. You will usually only need to kill the mob you just dropped down on.
