Celebrate the rich legacy and future promise of bicycle travel with Adventure Cycling Association's 50TH ANNIVERSARY DROP-IN RIDES. Spanning three iconic routes, these rides offer cyclists an unparalleled journey through America’s diverse landscapes. The TransAmerica Trail, marking its roots from Bikecentennial '76, stretches over nearly 4,200 miles from Oregon to Virginia. This route weaves through small towns and farmland, offering a glimpse of the original cross-country cycling adventure. Cyclists will traverse the majestic Rockies and Appalachians, connecting with the history that sparked Adventure Cycling’s journey. For those seeking an off-pavement challenge, the Great Divide Mountain Bike Route is the ultimate destination. Since 1998, this world-renowned trail has covered more than 2,700 miles from Montana to New Mexico, featuring gravel, dirt paths, and rugged mountain passes. It stands as a true test of endurance and adventure, inspiring riders worldwide. Adventure Cycling Association introduces the Golden Gravel Trail for its 50th Anniversary in 2026. This mixed-surface journey across plains, canyons, and mountains showcases America’s growing gravel culture and the future direction of bicycle travel. Riders will experience a blend of surfaces, from smooth roads to challenging dirt paths.
