Ran 4k last night and my tracks look like I was insanely drunk. I've never had this happen with my forerunner and all my runs with my 245 have had great tracking until this one run. Is there a glitch somewhere? I have it set to GPS + Glonass.

One single run is not worth mentioning 
en.wikipedia.org/.../Satellite_navigation_device
A satellite navigation device can retrieve (from one or more satellite systems) location and time information in all weather conditions, anywhere on or near the Earth. GPS reception requires an unobstructed line of sight to four or more GPS satellites,[2] and is subject to poor satellite signal conditions. In exceptionally poor signal conditions, for example in urban areas, satellite signals may exhibit multipath propagation where signals bounce off structures, or are weakened by meteorological conditions. Obstructed lines of sight may arise from a tree canopy or inside a structure, such as in a building, garage or tunnel.
