Guides

Practical, independent guides for Leadville and the high country around it. Written for people who are actually coming here: to race, to hike, to fish, or just to breathe the thin air. Updated as conditions and seasons change.

Altitude

Acclimatizing to 10,152 feet: the day-by-day schedule, what's normal, and what isn't.
Acclimatization for racers: the two-weeks-early vs. 48-hours question, and why the middle loses.

Race weekend

Leadville 100 crew & pacer resources: the curated index of guides from people who've actually run, crewed and coached this race, plus our race-day data.
16 years of race-weekend weather: every third Saturday of August since 2010.

The trip

Where to stay: in town vs. Twin Lakes, Copper, Frisco and Buena Vista, and how early to book.
Getting to Leadville: airports, the mountain approaches, and what winter changes.

Exploring

Mosquito Pass: the 13,185 ft road, when it opens, and the burro race.

More coming: MTB crew guide, aid station matrix, lottery explainer, winter guide, and a full lodging directory. The live dashboard is always the front door.
