Leadville Trail 100 Run

The start line sits at 3,100m, so runners from low elevations should arrive at least a few days early to acclimatize.

Weather on the Hope Pass out-and-back can turn fast, so carry a waterproof jacket, gloves and a hat even in August.

Daytime highs reach the mid-20s °C, nights drop close to freezing, and rain, hail, snow and lightning are all possible.

Time limit are based on gun time, while buckle times are chip time.

In 2026, the time limit was 2:15pm leaving Twin Lakes, 6:50pm at Winfield and 11pm back at Twin Lakes,

so if you hold back too much early on you will run out of time on the Hope Pass out-and-back.

Crews may help only at official crew points;

help anywhere else gets the runner disqualified.

Vehicles cannot enter Twin Lakes, so crews must take the shuttle from Outward Bound.

Pacer can join from the inbound Twin Lakes, one at a time, with a pacer bib and signed waiver.

Pacer may carry gear for you but may not push or pull you.

Drop off drop bags on Friday at the retail store, in clear plastic bags marked in large letters with your bib number, name and aid station.

Bags not collected by 5pm Sunday are donated.

Leadville has little lodging, so book as soon as you get your entry result;

on race day, athletes park at designated lots such as the Rodeo Grounds and take the shuttle to the start line.

The lottery has no application fee, and the entry fee is charged to your card only if you are drawn.

You can apply only once per person, and team entries were dropped from 2025.
