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 ($10 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.
Rocking out
Feel free to bring along your tunes and headphones, just keep the volume low enough that you can hear any instructions from course marshals.
Course cutoff

Everyone needs to get past Folsom & Arapahoe by 11:27am to stay ahead of the pro women who are blazing trail behind you. There will be a group of cutoff walker volunteers wearing bright orange shirts to help you stay on pace.


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 but must have their certified service vest visible.

Starting in a wave ahead of yours
You are welcome to move back to run with someone else, but if you move up to a faster wave you won’t be allowed to cross the start line or receive results.
