42: Colorado High Country

Colorado’s high country stands out as if a towering peak on the elevation profile of the CDT, exceeding 14,000’ (though my bike-legal route will top out at more like 13,200’).

After a second breakfast on my way out of Georgetown under blue skies and a warm sun, I steadily cranked out the 4,700’ climb up to Argentine Pass. Rejoining the CDT proper, I enjoyed the quick descent and began the next climb up with some uncertainty if I would be coming back down the same way in a few hours.

I had received contradictory information about the bike legality across this section of high terrain. Cotrex (the incredible government-sponsored one stop shop resource for all things Colorado trails) indicated that these trail sections were open to bikes. It was very much to my relief this afternoon to also find the official forced service sign post indicating that the trail was open to bikes. It actually makes perfect sense that this zone would be bike legal, given the extensive mining history and current motorized access in the area. For all that this area is a spectacular alpine zone, a pristine wilderness it is not.

The trail since Santa Fe Peak has varied among nonexistent but rideable, steep hike a bike, a few scrambling sections of carrying my bike across my shoulders, and some fun, fast downhill single track to round things out. I’m making slow progress through this section (as I expected) but am thrilled to be here. Tomorrow I will finish out the second half of this high traverse and connect to the Colorado Trail.

41: Weather Delay

I made it to Georgetown and picked up my resupply box around 10 AM this morning. From here, it’s over 13,000’ Argentine Pass into Colorado’s high country. Given the forecast of rain and thunder, I decided to treat myself to a low-key day waiting out the weather. I have since enjoyed a delicious and restful day cleaning my bike, drying out gear, and taking a moment to enjoy being on vacation. The forecast clears out tomorrow and I am looking forward to Climbing into Colorado‘s high country over dry trails and under warm sunshine.

40: Rollins Pass

Stayed in Winter Park last night and found a delicious breakfast from a cozy Czech bakery.

Easy climb up Rollins (4% grade!). The chunky road made for slow progress down, though with a fun surprise, when I rounded a bend, saw a person walking up the road with two dogs and unmistakable red hair and realized it was my friend Jessie with her pups and a backpack full of beer. The sun even came out while we sat watching trains move to and from the Moffat Tunnel.

After saying farewell, made steady progress climbing back up the next climb until heavy rain set in. I stopped off to wait out the rain. When the rain let up I resumed my slow progress on rocky, slick ATV trails, and passed through the odd collection of cabins in Alice, Colorado. I’ve never in my life seen so many no trespassing signs (or felt so tempted to poach one of the many hot tubs I saw along the way.

I reconnected with the CDT around 7 pm and soon found a campsite next to a creek (unfilterably cloudy due to the rain, as it turned out). Within minutes of finishing dinner the rain picked up again, and lasted through much of the night.

This is an odd section of my route. The CDT proper is high up in the wilderness areas, and my own route is constrained by geography, wilderness, and busy highways—all of which is to say this is mostly a “survival” section to get back to the next section of CDT.

39: Middle Park

Touched the southern end of the Never Summer Range before getting diverted south by wilderness. For the next few days the CDT goes into a series of wilderness areas, and my “alt” around these areas is a bit contrived.

38: Rabbit Ears Range Traverse

If I thought arrival in populous Colorado portended straightforward (if strenuous!) progress on well-travelled trails, I’ve been swiftly disillusioned.

Rather, today’s travel was one of my hardest days yet. My two great bugaboos on this trip (well, mechanical issues aside) showed up today in force: drenching, persistent rain; and, an unfathomable number of downed trees.

I walked around; stepped over with my bike; lifted my bike over then crawled over myself; or, crawled under probably 150 trees today. I managed an average speed of just two mph, hitting the trail at 7 AM this morning and pushing until after sunset (7:45 PM today) to make some 28 miles. One hiker commented, “channel your inner monkey, because this stretch is bananas.” Only above treeline did I make any sort of steady progress today.

Crossing over Parkview Peak today at 12,296’ is just a taste of what’s to come! I enjoyed spectacular views of the Never Summer range, where I ran my first ultramarathon some nine years ago.
