The loop-erased random walk is measure on non self-intersection paths obtained by erasing loops from a simple random walk. I will review what is known about this, including the dependence on the spatial dimension, and then discuss a new result showing the existence of the two-sided walk in all dimensions. The two-sided walk can be considered as the distribution of the ``middle’’ of a loop-erased walk.
