In 1979 we dreamt of attracting a few hundred of our friends to race through 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 10Ks in the world. Named Americas All-Time Best 10K by Runners World, it is the 3rd largest running race in the United States and the 7th largest in the world.

What’s Included
Park It

Parking near the finish line is available on the CU campus south of Colorado Ave. and Regent Dr. Pre-paid parking is also available.

Catch an RTD Bus

Whether you live in Boulder, Denver, Longmont or anywhere in between you can catch an RTD bus to the race. Check the RunRide schedule on the RTD website for updated bus information.

Your designated driver can drop you off near the start line at our runner drop-off area (see map). It is on the northbound 28th St. Frontage Road between Colorado Ave. and Arapahoe Ave. This area offers easy exit from the start area once you’re on your way.


Stadium Rules
  • Bags that are clear plastic and do not exceed 12″x6″x12″ are allowed.
  • Large bags, backpacks, and strollers are not permitted. Kid carrier backpacks are allowed. We do offer a mobile locker service ($5 race day), where you drop your gear at the start (Southeast corner of 30th & Walnut) and it will be waiting for you outside the stadium when you finish.

We want everyone to enjoy a fun and safe 10k on Memorial Day. Here are the do’s and don’ts for the day:

Running with little ones

All ages are welcome at the BolderBOULDER and we encourage you to make the day a family affair! Backpacks are great for walking with kids that can’t do it on their own but remember, strollers and baby joggers are not allowed.

Anything beyond your own two feet

You can walk, jog, sprint or skip – but please don’t bring bicycles, in-line skates, Kangoo shoes or anything else that lets you roll or bounce your way to the finish.

Walking or running with friends and family

It’s great to enjoy the day with your friends and family, but keep it to three abreast or less along the course so others can get by.


Go ahead and dress up however funny, funky or silly you like, but make sure your costume doesn’t extend beyond your body or connect you with anyone else.


Fido is a great training partner, but you’ll need to leave all pets at home on race day. Trained service animals are always welcome.
