The Triple Bypass Gran Fondo 2026, established in 1988, is a legendary ride covering 118 miles with over 10,800 feet of elevation gain across three mountain passes in Colorado: Juniper, Loveland, and Vail. Known for its challenging terrain and stunning scenery, the event attracts cyclists worldwide seeking to test their endurance and enjoy a fully supported ride. Participants are rewarded with a sense of accomplishment, a unique event jersey, and a finish line party, making it an iconic and noteworthy event in the cycling community.

Picked as one of our Best Road Cycling Events in Colorado and the Rockies, the Triple Bypass Gran Fondo 2026 was founded by a group of avid cyclists who thought it would be fun and challenging to ride from Evergreen to Vail, Colorado, and has turned into a premier bucket list event. The event is now produced by Shift Events, one of Colorado’s oldest and largest cycling clubs. All proceeds from the Triple Bypass are returned to local and national non-profits. Over $3M has been donated to groups ranging from High School Cycling to Bicycle Colorado.

The Triple Bypass Gran Fondo 2026 offers two main route options: the classic Triple Bypass, which covers 118 miles with 10,800 feet of elevation gain across Juniper, Loveland, and Vail Passes, and the Double Bypass, which spans 75 miles with 6,400 feet of elevation gain over Loveland and Vail Passes. Both routes start in Evergreen and Georgetown, respectively, and end in Avon, featuring scenic mountain views and challenging climbs. Most of the route is on closed roads or bike paths and escorted by Colorado State Patrol. The route includes four aid stations with great food and drink. Swag includes a complimentary jersey, full-ride support, a finished meal and beer, and timing.

This event is also a Gran Fondo National Series event and a qualification event for the USA Cycling Gran Fondo National Championship held in the Fall at Gran Fondo, Maryland.

Any event spanning 100 miles and 10,000 feet of climbing is difficult, but one important consideration for anyone considering the event for the first time in Rocky Mountain elevation. The event started in Evergreen, which is 7,000 feet tall and peeks at nearly 12,000 feet over Loveland Pass. If you don’t live at altitude, you must allow enough time before the event to acclimate.
