Unless you've had your head in a hole for the past week or so you probably know that it's Ironman weekend. It's not really my "thing", but from an athletes point of view it is definitely an epic day. The event will also make for an epic day of general navigation around the Truckee/Lake Tahoe area with road closures just about everywhere.
Next weekend (Sept 27-28) is the Little Big Ridestyle event at the Truckee Bike Park. This is a weekend for the ladies. Info here.
Or, if video is more "your thing"....
