First Friday 5k's After 5
Join us on the first Friday of every month, June through September, for a 5k untimed walk/run series along East Plum Creek Trail. Afterward enjoy live music, food trucks, cocktails, and more at Festival Park in the heart of downtown Castle Rock. Each Friday there will be a different theme for the race to go along with the live music performance that evening. Prizes will be given to best dressed, not who can finish the race the fastest. So come unwind after a long week with a beautiful trail run through Downtown Castle Rock and then stay for the free First Fridays, After 5 Concert Series in Festival Park!
You can register for the entire series or pick just one. Registration includes our swag item for each 5k, a beverage at the concert and different giveaways at each one for best dressed. Visit our First Friday's page for dates and information on each of the race themes.
