The second edition of the Mavic Haute Route Rockies takes in over 15,000 metres (50,000 feet) of climbing along its 850km (528 mile) route.
Boulder, Colorado, hosts the start of the seven-day ride on June 23 2018 which finishes in Colorado Springs, Olympic City USA.
The course includes a mammoth climb to over 4,200 metres (14,000 feet) at the summit of Pike's Peak-America's Mountain on the final stage, which is one of only two paved roads that reaches that elevation in the USA.
Also tackled during the week are the Left Hand Canyon on stage one, Sugarloaf on stage two and Trough Road on stage three. After an uphill time trial in Avon on stage four, riders will head over Battle Mountain on stage five before conquering Hoosier Pass as the fourth and final climb on stage six.
Micah Rice, Head of Operations for Haute Route North America said: "The second edition of Mavic Haute Route Rockies promises to be unforgettable, with breathtaking scenery and iconic climbs.
"As promised, we have eliminated all gravel sections and have kept only a few hard-packed dirt sections easily ridden on a road bike. These sections will showcase some of Colorado’s most memorable landmarks, enhancing the riders’ experience.
"We planned the route to make it easier for riders to recover after long days on the bike with two nights each in Boulder, Avon and Breckenridge."
As with other Haute Route events, those taking part will be treated as if they were a professional rider, with full support on and off the bike.
Haute Route North America Chairman Alain Lambert said: “Building on the success of last year’s inaugural US event, our Haute Route team has carefully planned the second edition of the Mavic Haute Route Rockies. The 2018 event truly has all the hallmarks of a great Haute Route.
“As an amateur cyclist myself who has ridden multiple seven-day Haute Route events, including the first edition of the Mavic Haute Route Rockies, I can state the 2018 edition will test cyclists of all levels and take their breath away with the quality of the parcours designed by our team."
Several levels of accommodation packages are available for riders tackling the event. Online entry is available now via the Haute Route website and the site also gives you more information on each stage.
