Many world class athletes train in Boulder for the high altitude, the friendly community, and the access to lots of great running terrain. The mostly-paved Boulder Creek path is a favorite, though there are many more streets and neighborhoods that are perfect for a quick run or a longer outing. If you prefer hills, Linden Drive and Table Mesa to NCAR are both fantastic road runs that require a good kick to make the it to the top. For less intense runs, there are many paths and trails connected throughout the city, from north to south. And let us not forget the Bolder Boulder, Colorado's classic 10k run that cruises the streets of Boulder and concludes with a single lap around the University of Colorado track in Folsom Stadium -- an unforgettable experience! The running community is strong in Boulder, so finding a group or buddy to run with will be easy -- just lace up your shoes and go.
