Dress up in some fun holiday regalia, including some lights!

Run one lap (2.8 miles) or 2 laps (5.6 miles) around Green Lake in your most festive holiday attire! Lights are encouraged! Collect your medal.Celebrate your achievement by dining on the finest cookies from Seattle's bakeries. Accept compliments regarding said medal on social media. Wear it to work on Monday.

Okay, so maybe it could be simpler.
