The GDMBR Route
Canada to Mexico along the spine of the Rockies — the ride, at a glance.
For many cyclists, bikepacking the Great Divide Mountain Bike Route (GDMBR) — mapped by the Adventure Cycling Association — is the ultimate adventure: a (normally) north-to-south journey from Canada to Mexico through snow-covered passes, high desert, and just about everything in between.
I'm following the traditional trail from Banff, Alberta, down through British Columbia, Montana, Idaho, Wyoming, Colorado and finishing in New Mexico — over 2,700 miles (4,340 km) and more than 150,000 feet of climbing, crossing the Continental Divide roughly thirty times along the way.

How long is the Great Divide Mountain Bike Route?
About 2,700 miles (4,340 km) from Banff, Alberta, Canada to the US–Mexico border at Antelope Wells, New Mexico. Most riders take four to ten weeks depending on pace.
How much climbing does the GDMBR have?
More than 150,000 feet (about 46,000 m) of total ascent, crossing the Continental Divide roughly thirty times.
Which states and provinces does the route pass through?
Alberta and British Columbia in Canada, then Montana, Idaho, Wyoming, Colorado and New Mexico in the United States.
Which direction should you ride the GDMBR?
Traditionally north to south, from Banff to Mexico, which lines up best with the snowmelt and monsoon windows. That is also the direction of the Tour Divide race.
When is the best time to ride it?
Roughly mid-June through September, once the high passes are clear of snow. The self-supported Tour Divide race grand-departs in mid-June.
Do you need a special bike?
No. A mountain bike or a sturdy gravel/adventure bike with tyres around 2.0–2.4 inches is typical — it is mostly dirt road and doubletrack rather than technical singletrack.
