Four great trailruns to choose from and they are all on Saturday so this leaves Sunday open for recovery. If you area looking for the hardest race choose the Rodeo Valley event. If you're looking to take it a bit easier but still challenge yourself head over to Woodside. If your looking for flat long distance's on dirt meet up at the Baylands Athletic Center in Palo Alto with the Zombie Runner Staff and hit the dirt fire roads of the marshlands. For a little Christmas cheer you can take it easy in Orinda at the Dam Jingle Bell Dash.
