Adventure Cycling‘s Great Divide Mountain Bike Route (GDMBR for short) is one of my favorite off-pavement bike routes in the country. I’ve done two tours of it myself while racing it, and have used segments the route itself quite a bit while doing shorter bikepacking tours. It’s well-designed, lots of beta about accommodations exist, and you’re bound to find like-minded people traveling on the route to bump into.
When I designed my Tour 14er, and later Highest Hundred tour, knowledge of the Great Divide Mountain Bike Route was key in piecing together my own custom route. It’s actually pretty surprising how many 14ers can be accessed without getting too far from the main GDMBR.
Here’s some of the more convenient detours off of the GDMBR to Colorado’s 14ers. Names of mountains will be linked with the appropriate route to the summit from the trailhead my directions give access to.
With another run of the Tour Divide this year, I’m reminded again of this awesome cross-country route and the many great memories I have on it.
The last time I was riding on the GDMBR was on my Tour of the Highest Hundred, where I rode up Marshall Pass after riding the 100 miles from Lake City to summit my first Sawatch of the trip: Mount Ouray.
The route itself was excellent, and provided a relatively quiet and mostly dirt route linking two disparate mountain ranges. The GDMBR barely gets into the San Juans, which is a real shame, as the San Juans are truly one of the crown jewels of Colorado. I’ll explain the route from Salida to Lake City, as this is where you’ll get on it via the GDMBR, then detour off towards Lake City. Once at Lake City, you’ll have to make a choice of where to go, as detouring back to the GDMBR is a trip in of itself and is also, sadly, all on pavement.
The Great Divide Mountain Bike Route is without a doubt one of the preeminent off road touring routes in the US/Canada. Now that I’ve ridden the route essentially twice and have done some extensive touring within Colorado, I can’t help but think how one could enhance it.
Personally, I enjoyed my time more when the route stuck close to the actual Continental Divide, rather than opting to drop down into a relatively easy going valley or basin to gain some mileage towards the end goal (finishing!). I always greatly anticipated gaining the summit of the passes, then rocketing down. Knowing Colorado a little more intimately now, it’s a shame how much of Colorado is missed with the relatively easy path the GDMBR takes.
The GDMBR has many goals, and one of the most important one is to get a heavily laden bicycle and rider (cyclists on a mountain bike, pulling a trailer) eventually to the end of the route. If the route is too long, too hard, and/or with too many Divide crossings, it’s just never going to realistically happen for a good majority of people. If we throw these constraints out of the window, and focus on the goal of staying as close to the Divide as possible, while also keeping the route terrain somewhat similar: gravel roads to 4×4 trails, we start drawing out something a little different.
Below, I’ll be describing a route that takes you off the official GDMBR just before Ute Pass, and rather takes you up and over the Continental Divide at Rollins Pass, parallels the James Peak Wilderness as you travel south to Idaho Springs, then brings you back west to go up and over the Continental Divide again at Argentine Pass, finally depositing you once again onto the official GDMBR in summit county. It circuitous and it’s a whole lot of fun .
One of the magical things about the Tour Divide is the MTBCast call-in service. If you can find a pay phone on the route – which are actually still, “plentiful” in the areas the GDMBR wanders through, you can call a 800 number and leave a message, that will then be posted up by MTBCast for everyone to listen in.
Four days, 420 miles, 4 continental divide crossings, 9 hours of snowshoeing, two days of minstrel headwinds,
snow showers and over-caffeine-ation.
“Well,” said the shaggy man, “let’s start on, or we won’t get anywhere before night comes.”
“Where do you expect to get to?” asked Dorothy.
“I’m like Button-Bright. I don’t know,” answered the shaggy man, with a laugh. “But I’ve learned from long experience that every road leads somewhere, or there wouldn’t be any road; so it’s likely that if we travel long enough, my dear, we will come to some place or another in the end. What place it will be we can’t even guess at this moment, but we’re sure to find out when we get there.”
“Why, yes,” said Dorothy; “that seems reas’n’ble, Shaggy Man.”
