Who should you actually listen to about crewing the Leadville 100?
The premise of this page: we're not going to tell you how to crew. The people below have run, crewed, paced and coached this race for decades; they've earned the right to. What we do is keep this index current, note what each resource is best for, and add the thing nobody else maintains: live conditions, 16 years of race-day weather, and road status for race weekend. Curated by hand, checked on a rotating schedule, last reviewed August 13, 2026.
Start with the official materials
Everything else on this page is commentary; the race organization's current-year athlete guide, crew rules and course updates are law, and 2026 matters more than most years because the courses were revised around the Willow Fire closures. Get them from the Leadville Race Series directly, including their When in Leadville local logistics page.
Coaching depth
Boundless Coaching is the Leadville-centered outfit here (the name is the elevation): LT100 Run and MTB coaching with guaranteed-entry packages, free race-prep webinars in the weeks before each event, a blog of race strategy and athlete stories, and a YouTube channel including a full film following an athlete through all 30 hours of the Run. We track their Leadville output and surface new pieces in the daily brief. Jason Koop (CTS) has finished Leadville, Hardrock, Badwater and Western States and coaches many of the sport's best; his book Training Essentials for Ultrarunning includes a course-by-course guide covering Leadville, and his Koopcast archive treats crewing as a performance discipline. CTS's ultrarunning library runs deep on race-specific strategy, and FasCat Coaching's Leadville 100 MTB material is the equivalent MTB starting point.
The sport's record
iRunFar's Leadville 100 coverage hub is the closest thing ultrarunning has to a paper of record: previews, results, and years of course analysis in one place. Their Then and Now piece is the best single read on how the race has evolved.
Firsthand accounts, the real texture
Nothing prepares a crew like reading people who've stood at Twin Lakes at dusk. Andy Jones-Wilkins' Leadville race plan shows how a veteran structures the day (older post, still instructive thinking). A return to crewing the Leadville 100 is a recent, honest crew-side account. GearJunkie's finisher account covers the gear side from someone who suffered for the knowledge, and this pacer/crew account captures what the day feels like from the support side. For the general craft of crewing and pacing any ultra, Treeline Review's guide is a solid modern reference, and Lifelong Endurance's LT100 FAQ answers the questions lottery entrants actually ask.
What we add on race day
The parts of crewing that are data, we maintain ourselves, daily: the live dashboard with start-line conditions and weather at Hope Pass elevation, what race day has looked like every year since 2010 (measurable rain in 12 of 16 years; pack accordingly), US 24 and CO 91 status including race-week construction, and the facts that don't change: there is little to no cell service at most crew points, so plans that depend on phones fail here. Lodging and getting here cover the rest of the logistics.
