In 1979 we created a 10K that wound through the streets of Boulder, Colorado. It was just our way of celebrating Memorial Day with family and friends. Here we are almost 40 years later, and we are incredibly humbled that the BOLDERBoulder has grown into one of the most highly acclaimed running events on the planet.

Each year we host 50,000+ participants and 70,000+ spectators at Folsom Field for what we like to call the biggest and best Memorial Day Party on earth. We’ve always believed that as long as we work hard every day focused on creating a truly unforgettable event, we can continue to live up to this expectation. 

We are incredibly humbled that Runner’s World voted us America’s All-Time Best 10K in 2009. Read what others have had to say about the BOLDERBoulder below.
