Event Description

Join The Memorial Day 10K Classic on May 27, 2019

We’re not sure when or how it happened, but somewhere along the way our little BolderBOULDER in Boulder, CO turned into an event of epic proportions. We like to think it’s part race, run, jog, walk, parade, celebration and tribute. We made it for everyone. Oh yes you can!


In 1979 we dreamt of attracting a few hundred of our friends to race though the streets of Boulder, Colorado to celebrate Memorial Day with our families. Fast forward almost 40 years and the BolderBOULDER has grown to become one of the largest and most highly acclaimed 10K’s in the world. Named America’s All-Time Best 10K by Runner’s World, it is the 3rd largest running race in the United States and the 7th largest in the world.

Almost 1.2 million runners, joggers, walkers and spectators of all ages have gathered over the years to create a spectacle that defies description. Olympic medal winners and hopefuls, grandmothers and kids, running enthusiasts and one-race-a-year guests from all over the world come together at the foot of the Rocky Mountains to form one of the sport’s truly unique events. Each year we host 50,000+ participants and 100,000+ spectators throughout the course for what we like to call the biggest and best Memorial Day celebration on earth.

The BolderBOULDER is still locally owned and operated, and our dream continues. This event has taken on a life that we never quite envisioned, and it rewards us every year beyond measure. We hope you will join us to celebrate fitness, our country and this great state of ours, Colorado.


Instead of one big start with all 50,000+ people taking off at once, we divide everyone into about 100 waves. Waves start with the fastest runners, then go to slower runners, then joggers, then walkers. Be sure to give yourself enough time to park and get to the Start Line.

The Push Rim Pro Race starts off every BolderBOULDER right before the “A Wave” at 6:50am. Come early to watch them fly through the course at an unbelievably fast pace.

The International Pro Race starts around 11:15 after the citizens race. Join us at Folsom Field to cheer them down the home stretch! And then stay for the grand finale, the Memorial Day Tribute, which starts at high noon. Start times are subject to change.
