The last 4 or 5 years or so, me and my best friend from my hometown have been running a 10K on Thanksgiving morning down in Belmont Shore in LB before we go off to our usual family activities. Pretty good way to get that appetite extra rolling before stuffing your face (and feeling at least slightly less guilty about it). Running that + usual Thanksgiving lunch at my folks' house = passing out extra hard by the afternoon football game... I haven't actually run that much lately though so I need to get back on my grind there.
