Important details:

• This is a series of untimed, fun runs. All levels of walkers, runners, joggers, and hikers are welcome.
• This is an open course, meaning roads will NOT be closed. You are responsible for obeying all traffic laws and regulations. The 5k and the 10k courses each have one road crossing that will be manned by voluneers. Additional volunteers and course markings will be present at all major turns and trail intersections.
• Water stations and bathrooms will be available along the 5k and 10k courses only.
• These are all true trail runs, which means you can count on a fair amount of elevation, challenging hikes, and descents on single-track bike trails, ski slopes, and mountain access roads. This course is not suited for running strollers, so please plan ahead if you have small children coming along.
• 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 kids (under 12 run for free) are welcome on the course! Note: this course is not suitable for strollers. Reminder: you are running at your own risk on trails, which might not be suitable for your child, or dog. Please make the best decision possible for you and your running buddies.
• Colorado Brewery Running Series merchandise, including shirts, hoodies, hats, stickers, heat press brewery logos, drinkware, and seasonal items that 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.
