Route Difficulty: While we awarded the GDMBR a difficulty rating of 5.5, it shouldn't be taken lightly. The surfaces and terrain that make up the GDMBR are largely gravel and dirt roads, and therefore not technical in nature. Most Tour Dividers cycle it with a drop-bar bike similar to the Salsa Cutthroat.

Stretching 2,745 miles from Banff, Alberta to Antelope Wells, New Mexico, it loosely follows the Continental Divide through the Rocky Mountains on a series of dirt and paved roads. The fastest men can complete the route in under 14 days, while most people who tour it take six to ten weeks.

And as long as bikes fall within regular checked baggage dimensions (62 inches and under 50 pounds), they can be checked for free with all your other luggage. If a bike is oversized or overweight (meaning it weighs 51 to 100 pounds or is 62 to 80 inches in total dimensions), expect to pay an additional $75.

The BikeFinder app allows you to always have an eye on your bike. Receive push notifications if someone moves your bike, check your tracker's battery level, and report theft directly on the app.
