Five decades after four cyclists pedaled into a vision that would transform the landscape of bicycle tourism in North America, Adventure Cycling Association stands as the nation's largest bicycle touring organization, having guided hundreds of thousands of riders through some of the most memorable journeys of their lives.
The story began in 1973 when Dan and Lys Burden and Greg and June Siple, inspired by their own ambitious Hemistour journey from Alaska to Argentina, founded what was initially called Bikecentennial. The organization's first major undertaking came three years later when more than 4,100 cyclists participated in the iconic Bikecentennial '76 celebration, a cross-country event honoring America's bicentennial.
Two thousand of those riders completed the entire 4,250-mile TransAmerica Bicycle Trail from Astoria, Oregon, to Yorktown, Virginia—a route that remains one of the most legendary bicycle tours in the world.
What began as a single ambitious event evolved into a permanent institution dedicated to democratizing bicycle travel. The organization survived the post-1976 era by recognizing that the impulse to explore America by bicycle was not confined to a single summer.
Instead of dissolving after Bikecentennial concluded, the founders leveraged the momentum and passion of that community to build something far more ambitious: a comprehensive network of routes, resources, and programming designed to make bicycle travel accessible to everyone.
Building the Foundation of a Movement
Over the following decades, Adventure Cycling transformed itself from a single iconic route into the developer and custodian of an extensive route network. By 2024, the organization had mapped more than 52,000 miles of bicycle routes across North America, with 23,000 of those miles integrated into the U.S.
Bicycle Route System. This vast network encompasses diverse riding styles and difficulty levels, from the original TransAmerica Bicycle Trail to the rugged Great Divide Mountain Bike Route, which traverses the spine of the Rocky Mountains over nearly 2,600 miles.
The publication arm of Adventure Cycling proved equally significant to route development. Beginning as "Bike Report" in 1974, the organization's magazine evolved into Adventure Cyclist, which has become a cornerstone of bicycle touring culture.
Currently reaching approximately 115,000 readers with a circulation of about 55,000 hardcopy subscribers, the magazine publishes stories, photographs, essays, and technical guidance from bicycle travelers worldwide.
The organization formalized its commitment to bicycle advocacy at the national level when it became instrumental in developing the U.S. Bicycle Route System alongside the American Association of State Highway and Transportation Officials.
Since 2005, Adventure Cycling has provided staff support and technical expertise to this multi-state initiative, helping coordinate the planning, designation, and promotion of interconnected bicycle corridors across the country.youtube
The Guided Experience Revolution
While routes and maps provided the infrastructure for bicycle dreams, Adventure Cycling's Experiences program delivered the human dimension. The organization pioneered the guided bicycle tour model specifically tailored to self-directed travelers, operating under the philosophy that each tour belongs to the riders, not to the organization.
In 2024, 497 riders participated in 51 guided tours across the continent, with many reporting a renewed desire to explore by bicycle after completing their journeys.
The organization expanded accessibility through its Adventure Grants program, which distributed $20,050 to 14 organizations and supported 497 individuals in pursuing bicycle travel.
Three Adventure Ride workshops held across three regions in 2024 provided foundational skills to aspiring bicycle tourists, with 90 percent of workshop participants expressing a stronger desire to continue exploring by bicycle afterward.
Expanding into the Digital Age
As technology transformed how people plan and navigate their travels, Adventure Cycling adapted its offerings. The organization partnered with Ride with GPS to make all 52,848 miles of its routes available with offline turn-by-turn navigation and rider condition reports.
This digital expansion made route information more accessible while maintaining the detailed field intelligence that has always distinguished Adventure Cycling maps from generic navigation platforms.
In 2024, the organization significantly expanded its Short Routes collection, curating over 40 regional rides designed for beginners and time-constrained cyclists. Each route was engineered to deliver meaningful bicycle travel experiences within a weekend timeframe at minimal cost.
Notably, Adventure Cycling launched a collaborative partnership with the East Coast Greenway Alliance to create short-route segments that highlight the intersection between bicycle travel for recreation and bicycle travel for everyday transportation.
The 50th Anniversary and Looking Forward
As Adventure Cycling approaches its golden anniversary in 2026, the organization is mounting an ambitious celebration that reflects both its heritage and its vision for the future. The centerpiece is the Golden Gravel Trail, a 3,700-mile bikepacking route stretching from the Mississippi River to the Pacific Ocean across eight states.
Representing a significant departure from Adventure Cycling's traditional pavement-focused touring routes, the Golden Gravel Trail emphasizes mixed-surface bikepacking and traverses the full spectrum of American landscapes, from Ozark hills to Great Plains to alpine passes.
Notably, Adventure Cycling is offering the Golden Gravel Trail free to the cycling community as a gift commemorating the 50th anniversary.
Unlike its legacy routes—the TransAmerica and Great Divide—which require ongoing updates and technical maintenance supported by map sales, the new route launches with a different economic model rooted in celebration rather than revenue generation.
The organization is staging the "Jubilee in the Desert" in Tucson, Arizona, from January 9-12, 2026, as the official 50th anniversary kickoff event.
The gathering will feature scenic day rides, community celebrations, and a reunion dinner designed to reconnect the far-flung network of Adventure Cycling members and volunteers who have shaped the organization over five decades.
Throughout 2026, the organization is encouraging cyclists to participate in "drop-in rides" on three routes representing Adventure Cycling's past, present, and future: the classic TransAmerica Trail, the contemporary Great Divide Mountain Bike Route, and the newly launched Golden Gravel Trail.
Professional cyclists including Sarah Swallow and Ryan Van Duzer are ambassadors for these efforts, pioneering route sections and sharing their journeys to inspire others.
The Deeper Mission
At its core, Adventure Cycling's 50-year trajectory reflects a fundamental belief: that the human spirit thrives on adventure, and that a bicycle provides an elegant mechanism to access that experience.
The organization's mission—to inspire, empower, and connect people to travel by bicycle—has remained remarkably consistent from its founding through the present day.
What distinguishes Adventure Cycling from simple commercial tour operators is its commitment to making bicycle travel a reality for ordinary people rather than affluent adventurers.
The organization has consistently focused on democratizing access, providing maps and routes suitable for riders of all skill levels and budgets, offering graded tours that serve novices alongside experienced cyclists, and advocating at policy and infrastructure levels to make bicycle travel safer and more viable.
The membership community that Adventure Cycling has built over five decades represents the tangible proof of this mission's power.
More than 23,000 members currently sustain the organization through membership dues, representing a commitment to a vision that bicycle travel can enrich human experience at scale.
As Adventure Cycling enters its second half-century, the organization faces both familiar challenges and new opportunities. Membership numbers have fluctuated as demographics shift and recreational preferences evolve, yet the core mission endures.
The expansion into gravel bikepacking through the Golden Gravel Trail signals the organization's willingness to evolve its route portfolio in response to changing cycling practices. The continued publication of Adventure Cyclist magazine, now in its 50th volume, maintains the editorial voice that has long chronicled the subculture and culture of bicycle travel.
Five decades of making dreams come true stands as a testament not merely to institutional persistence, but to the enduring power of a simple idea: that people should have access to the tools, knowledge, and community support necessary to travel by bicycle across their own continent and beyond.
Adventure Cycling's next chapter will determine whether that vision continues to resonate with generations of cyclists yet to pedal into their own adventures.
