The "Race Across the Sky" earns its name. This 100-miler never drops below ~9,200ft, and the whole story is the thin air, not the vert. A famous, hundreds-strong, lottery-entry ultra run entirely up in the Colorado Rockies.

What Leadville throws at you

Typical sessions

Altitude that never lets up: above 9,200ft the whole way, over Hope Pass at ~12,600ft twice.

A runnable course that tempts you to bank time you repay with heavy interest coming home.

The Hope Pass double, worst on the second crossing with tired legs, where the cutoffs bite hardest.

A long, cold night: most of the field runs into darkness and the second morning.

What your weeks look like

Typical sessions

Runnable long runs from 3-6h, building to a 7-9h ultra-long day on the highest ground you can reach.

Hope Pass sims: a double-climb of one hill in a single run, plus power-hike repeats with poles.

Back-to-back weekends, a big Saturday of 6-7h and a tired-leg Sunday of 4-5h, plus night runs on your race headtorch.

An altitude plan that peaks late, camp high or sleep-high tents, with fuelling rehearsed at 60-90g carbs per hour.
