Boos & Brews Halloween 5k @ Number 38 | 2026 CO Brewery Running Series

Join us for The Boos & Brews Halloween 5k @ Number Thirty Eight on October 31, 2026, for a 5k run that starts and ends at this awesome taproom in Denver. Run, walk, jog - whatever goes! Complete the course and celebrate with a cold, delicious beer at the finish line.

Start times will be available at 10:00 AM & 10:30 AM.

As this is our annual Halloween event, we encourage you to come in costume! We'll have a costume contest and trick-or-treating for any kids (or kids at heart). Hope to see you there! Kids under 12 run for free!

• (1) free craft brew at the finish line from the brewery
• Choice of a collector’s pint glass or seasonal swag item from the Brewery Running Series
• A chance to win sweet prizes, like Brewery Running Series merchandise or beer to take home
• Access to event festivities like live music, games and goodies with our partners and sponsors
• And more!

Be active. Have fun. Give back! A portion of all proceeds supports local nonprofits.

Registration is limited to the size of the taproom, and many of our events sell out. Sign up today!

• This is an untimed, fun run. All levels of walkers, runners, and joggers are welcome.
• This is an open course, meaning roads will NOT be closed. You are responsible for obeying all traffic laws and regulations.
• We create each route to start and end at the brewery and to show off the surrounding neighborhood. The course will be marked with arrows and volunteers to help you know where to go.
• You must bring a valid ID or driver's license. You do not need to be 21 to enjoy the event, but you must be 21 to enjoy the beer. Please drink responsibly. Registered, underage participants will receive a token for a FREE non-alcoholic beverage.
• Our events are rain or shine! If conditions become unsafe to run, we will still hang out and drink beer.
• There will not be a bag check; please plan accordingly and dress appropriately for the weather.
• Dogs and strollers are welcome on the course, with care and caution. Please remember - you are running at your own risk on city sidewalks/streets/trails, which might not be suitable for your 4-legged and /or pint-size running buddies. You will also want to check with the brewery to make sure you can abide by their dog / underage policies. Please make the best decision possible for your crew.
• Colorado Brewery Running Series merchandise, including shirts, hoodies, hats, stickers, drinkware, and seasonal items will be available at the event.
• There is public parking available. Is public transit an option for you? Check and see if there’s an accessible route nearby.
• Please drink responsibly. We always encourage carpooling and safe, designated drivers.

Keep an eye out - we will send you all final event details via email the week of this event and share anything else you might need to know.
