* The BOLDERBoulder 10K would like to extend its appreciation to active duty and reserve military members of all branches of the U.S. military by offering a $15 discount to those currently serving our country. Memorial Day has always been BOLDERBoulder Founder Steve Bosley's favorite holiday and the race believes in honoring those who serve and those who have given the ultimate sacrifice in service of their country.

Military Discount Details:
1. Active duty military or Reserve and National Guard are eligible for the $15 discount.
2. Although we also thank them for their sacrifice, the discount applies to service members only, not family.
3. Any questions please contact us.

An important part of the BOLDERBoulder is to honor the men and women who have served our country. Make sure to join us for our Memorial Day Tribute after you run. Watch the Memorial Day Tribute Video to learn more, here.

Run with the Buffs
Calling all University of Colorado Boulder students, alumni and fans! Run, jog, or walk with fellow CU Alumni, coaches, spirit squad and everyone’s favorite mascot, Chip! When you register, select “Run with the Buffaloes in the CU wave”. All CU wave runners will also receive a special #ForeverBuffs back bib. After the race, take your bib to the CU Alumni tent at Expo to receive a free gift.
Pick a Wave

Even though the overall 10K race is big, it’s really about 100 separate smaller races that let everyone go at the gun and finish at their own pace.

The waves are divided up into six categories: qualified runners (ones with proof they can run under 68 minutes), runners, joggers, jog/walkers, walk/joggers and walkers.

Your estimated finish time determines your category. If you are using a qualifying time, make sure you have your proof of qualifying before you register. If you want to start with someone else, register together. You will then be placed in the slowest requested category of your group.

Several special waves have been designated for specific groups such as the BBRacers Club (formerly the Middle School Challenge), KBCO, University of Colorado Boulder and Military waves.

Learn how our waves work.

Folsom Field's Clear Bag Policy

We’re celebrating the BOLDERBoulder in CU’s house, so we follow their house rules. CU Stadium has a clear bag policy!

In 2018, the CU’s Clear Bag Policy will be strictly enforced at Folsom Field. They allow you to bring in one clear bag no larger than 12 inches x 6 inches x 6 inches, or a one-gallon resealable clear plastic bag, into the stadium. Bags that are no longer allowed into Folsom Field include backpacks, camelbacks, large purses, oversized tote bags, camera bags and binocular cases, diaper bags, fanny packs and printed plastic bags.

Clear bags are becoming the norm at athletic venues across the nation. They aid in increasing participant safety and decreasing the waiting time to enter stadiums. For more information on the CU Clear Bag Policy, click here.
