14 Cool and Crazy Guinness World Records Held in Colorado

Colorado is famous for a lot of things: world-class athletics, destination snow sports and amazing mountain views you won’t find anywhere else. According to the Guinness Book of World Records, we could add motorcycle poker runs, roller derby, gorilla costumes and dog weddings to that list, too.

To show off our charitable, quirky and impressive residents, organizations and local businesses, we rounded up a handful of Colorado world records you should know about. If you search the archives yourself, you’ll also find plenty made at Coors Field, inside the Pepsi Center and at the Winter X Games, but we limited this list to the charitable, cool and downright strange.

In 2015, the City of Greeley held Chalk-a-lot, an event that would highlight the community’s artistic culture and show off the Greeley Creative District, which is home to the city’s highest concentration of arts-related businesses. The 3.55-mile stretch of chalk art wound through two University of Northern Colorado parking lots and beat out the former record holder—a German city called Jena—by 400 feet.

You can see more photos of the event on the Cloudgate Aerial Cinematography website.


Most points scored in a WFTDA Roller Derby power jam by an individual

Broomfield | Recorded April 2013

Though recorded in Broomfield at the First Bank Center, this world record was broken during a roller derby bout between FoCo Girls Gone Derby (now known as FoCo Roller Derby) and Castle Rock ‘n’ Rollers. FoCo player Megan Lazorski (known on the rink as Slim Skatey) took home the record after scoring 50 points in a power jam, which if you didn’t know, is when the other team’s jammer has been sent to the penalty box leaving only one team’s jammer on the track to score.

Most balloons blown up in one hour by an individual

Allenspark | Recorded September 2015

Guinness World Records broken in Colorado

Hunter Ewen had a lifelong fear of balloons and a desire to overcome that fear. So, in 2011, he did it in the most fun way he could think of. He inflated 582 balloons in 60 minutes. After being unseated, he took the record back in 2015 with a whopping 910 balloons in one hour! The official measurement took place at the Wild Basin Lodge and Event Center in Allenspark and Hunter lives in Boulder.


Loudest bark by a group of dogs

Denver | Recorded November 2009

In November 2009, 76 dogs and dog lovers came together with Petmate in Denver’s Washington Park to help raise food for local dog rescues and break a world record. Together, all 76 dogs barked to reach 124 decibels! And all owners donated at least one tin of unopened dog food.

Largest gathering of people wearing false mustaches

Denver | Recorded November 2015

In 2015 during the same month as Movember, UCHealth and the Denver Broncos hosted a record-breaking event to raise awareness for issues affecting men’s health, including prostate and testicular cancer. During a blizzard, thousands of fans inside the stadium donned their free orange mustaches two minutes before halftime to set the record. Though the number was officially recorded by Guinness at 6,471 people, attendance at the game was closer to 77,000, and people all over the country joined in on social media.


Greatest vertical distance rock climbing in 24 hours

Boulder | Recorded May 2011

Guinness World Records broken in Colorado

It’s no surprise to hear a rock climbing record was broken in Boulder. In 2011, Will Levandowski climbed 29,130 total feet in just 24 hours on Flagstaff Mountain near this foothills town. He climbed a 10 foot, 1.25 inch rock formation a total of 2,883 times.


Deepest geothermal hot spring measured by a plumb line

Pagosa Springs | Recorded August 2011

A must-see destination that we highlighted in 18 Colorado Hot Springs You Need to Visit this Year, The Springs Resort & Spa has 23 pools located along the San Juan River in Pagosa Springs. In 2011, the ancient geothermal hot spring was measured by a plumb line that reached 1,002 feet, and that measurement didn’t stop because they reached the bottom. The line ran out before they could! Today, the actual depth of the spring is still unknown.
