The weather outside is frightful….
So if you’ve already forgotten to get that Halloween costume and you don’t feel like doing the last minute idea, grab a bike or some running shoes (and that last minute costume) and get outside. 
Bike Jerks is putting on the Track or Treat (fixed gear only). Alley Cats are always fun, but doing it on Halloween night should be redonkulous.
And if that doesn’t tickle your fancy, check out Team Orthos’ Monster Dash 1/2 marathon, 10 mile and 5k at Lake Harriet this Saturday. Afterwards, there will be a party (21+) at the convention center.
That Track or Treat poster is awesome.
