7:15-8am - Arrive @ Eben G. Fine Park, check in at the stone shelter (all you'll need is your name since you already registered), get your wristband, pump your tube if you haven’t already, play some games, catch some flying neckties, dance!

8:05am - Opening Speech

8:15am - Ribbon is cut, proceed through "the gauntlet," to the official put-in; hold up your wristband, helmet on, life jacket visible. We'll let a wave of tubers in the water, quick break then another wave and so on.

8:45 - 9:45am - Hot coffee, lite breakfast and DJ dance party at Boulder Central Park

9:45 -10am - Tube onwards from Central Park or set off on foot to downtown offices.

Tube to Work Day History

A tale as old as time

Tube to Work Day began in 2008 as a joke between friends Jeff Kagan and Andy Gruel - an audacious quest to see if one could actually commute to East Boulder offices without the use of fossil fuels. Attendance was slow to catch on until 2012 when 2 other intrepid tubers joined the friends swelling participation to 4! Even with minimal participation the media has always loved/covered our event and notoriety participation jumped each year. 8, then 20, then 50, then 200, then 500 and finally topping out at over 1,000 tubers in '18 and '19 before COVID put the flow on hold for 2 deflated years.


Now Tube to Work Day is back and inflation in Boulder has never been greater! Over the years we've seen it all - sopping wet business suits in cubicles, bacon and OJ fished off the bridges, mad hatters, cheetahs, sharks and hamburgers floating the Class 2 rapids, a massive floating unicorn that somehow made it to the breakfast at Central Park and mermaids lining the banks with squirt guns. The event has been described as an "Only in Boulder" kind of thing and we agree. It has always been about the love of our natural waterway, the thrill of tubing enmasse, networking in moist clothing and getting weird, wet and wild with our Greater Boulder business community. From the humble beginnings of 2 friends seeing if it could be done (and it can!) to the current evolution of hundreds of fun/coffee-loving commuters we invite you to be a part of the history in '23!
