If you want to use an event to motivate you look for something small like a 5K for charity or a mud run. The mud runs/obstacle courses are tons of fun. Lots of events these days have beer at the finish line :)
Very nice. My personal favorite seasonal is Octoberfest. If you want something to kick back and relax with, see if you can find SA Boston Ale. Not lager. Ale. Total Wine usually has it in stock. You won't be disappointed.
