Day 18 of a Colorado Trail thru-hike reads like a highlight reel of what long-distance walking in the Rockies actually feels like: sticky mornings, ski-resort detours, brutal sun at altitude, and a race against afternoon storms.

The hiker started near Ten Mile Creek around 7:20am, packing up a tent made clammy by condensation from camping too close to the water. After crossing a highway that turned out less intimidating than expected, the route wound through forest and then straight into Copper Mountain ski resort, where construction forced roughly half a mile of pavement walking past chairlifts and the resort's roller coaster before the trail climbed back into the trees.

The meat of the day was a long, exposed climb to about 11,700 feet up a creek valley, much of it in full midday sun. Sunscreen was reapplied several times, and the trail chat with other hikers offered some reassurance: one, a PCT veteran rehiking Colorado after last year's Continental Divide Trail, reckoned Colorado's CDT section was genuinely hard — welcome context for anyone finding the CT tougher than expected.

Then came classic Colorado afternoon weather. With just 0.2 miles to the cabin cutoff, storm clouds rolled in fast enough to force a 'thunder break'. A mountain biker from Seattle topped out at the same moment, visibly nervous about riding on toward Leadville in that weather — a reminder that summer afternoons above 11,000 feet are no joke whether you're on foot or on wheels.

The day ended at Janet's Cabin, reached by an annoying downhill that gave back all that hard-won elevation — with the promise of a half-hour uphill slog the next morning, hauling a full day's water at altitude. The payoff: an entire backcountry cabin to yourself. Quiet, yes, but a little creepy when you're the only guest.

Why care? This stretch between Ten Mile Creek and Janet's Cabin is a realistic snapshot of the Colorado Trail's central section near Copper Mountain and Leadville — gorgeous, exposed, and weather-dependent. If you're considering hiking or biking it, the practical lessons here apply broadly: start early to beat the sun, plan to be below treeline or under shelter by early afternoon in monsoon season, carry more water than feels necessary on exposed climbs, and know that hut-to-hut options like Janet's Cabin can take the edge off multi-day trips, even if sleeping alone in one takes some getting used to.
