Photos: Highlights of the 18th Tube to Work Day on Boulder Creek

On a sun-drenched Friday morning, hundreds of commuters dressed in soggy business suits, full-body Buc-ee the Beaver costumes, and '80s-themed workout apparel swapped rush hour traffic for Boulder Creek. The 18th annual Tube to Work Day turned the city’s downtown waterway into a churning current of inflatable inner tubes, fox-themed floatation devices and fluorescent fits, as participants bobbed through Class II rapids on their way to work.

The annual event, which started with just two participants and a dream of eco-friendly commuting, has evolved into a full-blown spectacle. Now boasting several hundred tubers and even more spectators cheering them on from the creek's edges, Tube to Work Day is part alternative transit experiment, part community celebration and part river-bound costume parade.

Attendees began trickling into the Eben G. Fine Park around 7 a.m., greeted by games, dancing and a stilt-walker parade. The weather cooperated: clear skies, mid-60s temperatures that rose to the low 70s and no wind made for ideal tubing conditions. First-timers and seasoned veterans mingled as they inflated tubes, zipped wetsuits under their collared shirts and mingled with others about to take the plunge.

Before tubing began, Kagan surveyed the crowd, asking for a show of hands from newcomers, returning veterans and those who showed up with ten or more colleagues from their office. This year's event had "record-setting" office participation.

“Well, whether it’s your first time or your 18th, which I’m pretty sure is just me, we are in for a fantastic commute today,” Kagan said. “Look out for donuts from above. Whitewater below. Mermaids with squirt guns on the banks. And of course, do not miss the pullout at Central Park for the coffee breakfast dance party.”

A few lucky participants walked away with prizes before the send-off. This year’s Best Tube awards went to a giant inflatable squirrel and a community of floating foxes. The Best Dressed category honored one tuber in full business attire carrying a laptop and another with a disco helmet, disco ball necklace, green mesh shirt and bright pink shorts and leggings.

Then, for the first time in the event’s history, Kagan invited two “honored dignitaries” to the stage. “Please welcome to the stage our first dignitary, a devoted advocate to alternative transportation, your City of Boulder Councilmember, Mr. Ryan Schuchard,” Kagan announced. “And making his first appearance ever at Tube to Work Day, our beloved United States Colorado Congressman, give it up for Joe Neguse.”

“Let’s give it up for Jeff!” Schuchard said, taking the mic. “Hello, Boulder. I would just like to recognize all of the tubers who have gone before, and our best tubing is ahead.”

At 8:15 a.m., a ribbon duct-taped to a saw blade was sliced in half by Neguse and Schuchard. With wristbands raised and helmets buckled, waves of tubers launched into the current. Some paddled in sleek river gear; others grinned in dripping button-downs and wacky costumes.

Spectators along the route handed out Bloody Marys. People tossed powdered donuts from bridges near the library. A few surprised passersby shouted encouragement from the bank. For many, the event’s highlight came at Central Park, where the tubing route ended with hot coffee, breakfast bites and a dance party led by DJ Superstar Duck Low Rock.

The event also served a greater purpose: 25 percent of ticket sales went to Bridge House, a local nonprofit that helps adults experiencing homelessness through employment and housing programs. While many people left at the designated exit, others removed their wristbands and continued tubing downtown after the official event ended.
