  Looking for something to do with the whole family on Father's Day Weekend? Look no further than the Happy Hour Half K on Friday, June 19, starting at 6:00 p.m., at Civic Green Park in Highlands Ranch.

  Have you always wanted to run a half-marathon, or maybe just a 5K, but it seems like too much work? You're in luck! Join us for the 1640-foot Happy Hour Half K benefiting the HRCA Therapeutic Recreation Program. There will be:

  🚶 A family-friendly 1640-foot "race" around Civic Green Park in Highlands Ranch Town Center featuring...

  🍩 One aid station offering water and sustenance (phew!) to help you make it to the finish line

  💃🏽 Live music

  🍺 Local beer, seltzer, wine, and non-alcoholic beverages free for participants (2 each)

  This is a non-timed race because everyone is a winner! Haven't started training? No worries... neither has anyone else!
