First of all, if you haven’t been watching the USA Pro Cycling Challenge, you should be. Or at least you should be recording it on your DVR so you can see it when you get home from work. It’s on Versus. Or here. That’s your homework for the week.

Your other assignment is to bike Fremont Pass, though maybe it’s better to say “brave Fremont Pass.” It’s kinda scary but generally worth it.

So here’s the thing, if cycling were all about discovering Colorado mining history, every guide would list riding Fremont as the state’s best ride. This pass counts four mining towns–three of them extinct–one truly enormous excavation, and all the hallmarks of an extractive industry boom. You’ll also run across three 14ers, a couple mountain lakes and more traffic than you can stand. With the generally crappy road added to the mix, it all makes for a bittersweet cycling experience, at least on the weekend. This is the sort of ride that makes you dream of flying along a fresh strip of asphalt on a quiet Tuesday morning.

If only it were so.

Anyway, if you’re planning to bike Fremont, here’s what you need to know: compared to other Colorado passes, this one’s fairly easy, but the rides on either side couldn’t be more different. From Leadville heading north, the road slopes gently to its summit, only really gaining elevation on the final ramp. From Copper Mountain heading south, the route climbs a healthy 1,750′ over 6.5 miles, topping out at an eight percent grade.

Let’s take a look at the details.

Your best bet will be to exit from I-70 at Copper Mountain and park in the lot that’s a half mile or so down the road on the left hand side–across from the golf course. Leaving the parking lot, take a left, south, on Colorado 91. You’ll get about a mile or so to warm up, and to assess your comfort level with all the traffic. It gets no better. (As an aside,  a drunk woman in a Dillon brew-pub told me she’d never bike CO 91 because there were, she said, too many tourists gawking at scenery and driving all over the damn place. She’d never do it, she concluded. Of course, I don’t know if she’d every really bike anything–and she was drunk–but you’ve been warned.)

After the first mile, the gradient increases, hitting an average of 3.9 percent for then next several miles, but if that seems a little weak sauce, it’s not. At times, the road turns upward, climbing at better than 8 percent. And it never really seems to back off in the way sections of Lookout Mountain do. Along the way, you’ll catch glimpses of Ten Mile Creek, which cuts from the left, the runs under the road and appears again as a more expansive valley opens up to the east.

It’s here, about four miles in, that you’ll catch the first signs that something is amiss. Gates block roads leading off to the right, each of them bearing ominous “No Trespassing” signs. Then, the tailings ponds, with quaint names like “Mayflower” and “Robinson.” If they look unnatural, it’s because they are.

Essentially everything in the valley to your right is the result of molybdenum mining, and these tailings ponds imprison the byproducts of that process. Unlike the gold and silver that brought most folks to the mountains early on, molybdenum appeared on the scene because of its industrial applications. You probably know it from old bikes; that “chromoly” is a form of steel, hardened with molybdenum. But before it became popular for bikes, most molybdenum went into production as America entered World War I. As world demand for the ore has ebbed and flowed, the Climax mine higher up the hill has operated in fits and starts. At one point, though, it shipped 75 percent of all the molybdenum on earth. It’s closed now, but a recent Denver Post article suggests the production will begin again. Soon.

About three miles from the true summit, the hard climbing ends and the rollers begin. The first takes you down, almost level with a reservoir that offers a view toward the back of the Ten Mile Range. From here the road rises and falls slightly, and just before the final ascent the summit, the route provides a pull-out with views toward Mount of the Holy Cross. A few signs describe the area’s gold mining history, including the expansion and desertion of a few mining towns, and suggest that the Climax mine is doing its best to restore the valley to its original state, bulldozers, backhoes and denuded earth not withstanding. From here the road eventually winds up in front of the Climax mine itself. Curiously, the 11,318′ summit lacks the standard sign indicating the accomplishment, but not to worry, you’ll find something better: old mine cars and a dude selling elk jerky. To the north is the mine, a colossal affair that has dispatched with most of the visible hillside behind it.

Descending from the summit, the road improves significantly, and you’ll ride happy on new pavement. If you climb passes for the heart-pounding descents, though, the south side of Fremont will disappoint. It’s pedal pushing all the way into Leadville, although the road does meander alongside a pleasant creek for most of the way, and to the east you might catch the scenic railroad winding its way along the slopes. The highway pitches up again just before entering Leadville, and the first junction offers a chance to complete the second leg of the Copper Triangle, a breezy 35-mile ride into Minturn. But for now, stay the course and enjoy a snack or lunch in Colorado’s could-have-been capital.

I’m still figuring out when I want to write my Leadville post, but it’s still not now. Suffice it to say, you should skip the Golden Burro Cafe (all the time) since it hates cyclists, and try the Tennessee Pass Cafe instead. Its reasonably priced food from every standard ethnicity—including Indian—gets most everything right. There’s beer on tap, too, if you’d like, but don’t count on speedy service.

Heading back to Copper Mountain, there’s not much to say about the ride north. Compared to the north aspect, this side of the the pass seems essentially flat until the final ramp up to the mine, then prepare for a screaming descent into Copper. I’d suggest erring toward the shoulder to avoid the cracks, potholes and outright fissures that crisscross the lane. But by the time you read this, it may have been repaved, and if so, then by all means, try to set a new max speed. It’s a nearly a straight line into the starting parking lot.

And that’s it. Cross Fremont off the list. Then come back next weekend to give Tennessee Pass a try.

Bottom Line: Fremont is a Colorado essential, but one best attempted on a weekday. Completely repaved, it ought to be a dream.
