Memorial Day 2026 is calling.

On Monday, May 25, more than 50,000 runners, joggers, walkers, and dreamers will flood the streets of Boulder for the 46th running of the Bolder Boulder 10K .

If you’ve been on the fence, here’s your sign: this race delivers an experience you won’t find anywhere else.

The Stadium Finish That Gives You Goosebumps

Imagine grinding through 6.2 miles at altitude, turning the corner, and suddenly hearing thousands of voices roaring your name as you burst into Folsom Field.

The grass under your feet. The stands packed with spectators. The electric energy.

It feels like crossing the finish line at a college football game… except you’re the star player.

Runners consistently call this the highlight. You don’t just finish a race; you get welcomed like a hero into one of Colorado’s most iconic venues.

Then stick around for the professional race finish and the massive Memorial Day Tribute at noon, one of the largest in the nation. It’s patriotic, emotional, and the perfect cap to a day of personal victory.

For Every Pace, Every Person — “Oh Yes You Can!”

The race invented the wave start system back in 1983, and they’ve perfected it.

No chaotic mass start with 50,000 people tripping over each other.

Instead, participants are placed in waves matched to their pace, whether they’re chasing a sub-40 PR, jogging comfortably, or walking with friends and family.

This inclusivity is baked into the event’s DNA.

“Oh Yes You Can!” is the official mantra.

Families, first-timers, elites, costume crews, and everyone in between show up.

It removes the intimidation factor that keeps many people from signing up for big races.

Scenic Course + Boulder Energy = Pure Magic

The point-to-point course winds through vibrant Boulder neighborhoods lined with cheering crowds, live music, kids with sprinklers and slip-n-slides, and that classic Colorado sunshine, with the iconic Flatirons as your backdrop.

At more than 5,400 feet above sea level, the altitude adds an extra challenge, but the views and support make every step worth it.

This isn’t just running.

It’s a moving street festival celebrating community, fitness, and Memorial Day.

Swag, Tradition, and That “I Am Bolder” Feeling

Registration includes your choice of official race shirt, with special retro designs this year celebrating major milestones, a finisher medal, timing chip, and more.

Add-ons like the limited CU Wave shirt make it even more personal for Buffs fans.

Since 1979, this event has grown from a few thousand runners into one of the largest and most respected 10Ks on the planet.

Runner’s World once named it “America’s All-Time Best 10K.”

That legacy hits differently when you’re part of it.

It’s More Than a Race — It’s a Memory You’ll Chase Forever

The race isn’t about perfection.

It’s about showing up, pushing your limits—whatever they are—and soaking in one of the best days of the year in one of the best places on Earth.

You’ll leave stronger, prouder, and already planning your return.

So why run this race?

Because on May 25, 2026, Boulder will be alive with bold energy, and there’s a spot on that start line with your name on it.

Who’s in?

You’ll thank yourself when you’re standing on that Folsom Field grass, medal around your neck, heart full, yelling:

“I AM BOLDER!”
