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 boldest Memorial Day tradition 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.
