    About the event
    From the organiser

    The Colorado Mountain region has amazing attributes and recreational opportunities to explore. Boulder is known as the happiest city but we beg to differ. We think it is the hoppiest city with over 15+ craft breweries. Enjoying the mountain fresh air while running with friends and sipping local craft beer from Fort Collins to Boulder creates one amazing experience: The Boulder Beer Chase.
