Who should you actually listen to about crewing the Leadville 100 MTB?

The premise of this page: we're not going to tell you how to crew a hundred-mile mountain bike race. The people below have ridden, won, coached and supported this one; they've earned the right to. What we do is keep the index current, note what each resource is best for, and add the thing nobody else maintains: live conditions, the race-window weather record, and road status for race weekend. Curated by hand, checked on a rotating schedule, first published August 28, 2026.

One date matters for everything below: the 2026 races ran on courses rerouted around the Willow Fire closure, with Hagerman Pass Road, Sugarloaf and Powerline off the course and the aid and crew map redrawn. Anything written before August 2026 describes the traditional line. The craft in those pieces holds up; their mileages and location names may not, and nobody knows yet which course 2027 will run. Check the current year's official materials before you plan anything.

Start with the official materials

The race organization's current-year athlete guide, crew rules and course updates are law. The official Leadville Trail 100 MTB page carries the aid-station table, crew locations and cutoffs for the current year. The series' own MTB crew checklists are the rare official document written directly to the crew: what to stage, what your rider will actually want, and what to stop asking them. Their When in Leadville page covers the town logistics around it.

People who have won this race

Dispatches from Columbine: your questions answered by Dave Wiens and Rebecca Rusch is ten championships' worth of answers on pacing, support and the day itself, published by the race. When their advice and a random forum thread disagree, this is the tiebreaker.

Coaching depth

Boundless Coaching is the Leadville-centered outfit (the name is the elevation), with MTB and Run coaching, pre-race webinars and a blog that works the race-specific details; their MTB carb-loading and last-minute fueling guide is the piece a crew can act on directly, because the eating starts before the gun. FasCat Coaching's Leadville 100 MTB material covers pacing and strategy for the traditional course profile, and TrainerRoad's Leadville 100 guide is the structured-training entry point, with a deep forum behind it.

Race-day arithmetic

Best Bike Split's Leadville 100 course and pacing page models split times from power and course data. A crew that knows the rider's target power can read arrival windows from it instead of guessing, then verify against the official cutoffs. Velo's gear tips for you and your support crew covers what actually gets handed up: wheels, layers, and the checklist thinking behind a fast exchange.

The crew-side account

Kaizen Endurance's How to Crew for the Leadville Trail 100 MTB is the single most complete crew-side walkthrough we've found: station choice, arrival math, what to carry, and the rules that trip people up. Written to the traditional course, so carry its craft and not its mileages into a reroute year.

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 course elevations, the hour-by-hour course forecast matrix that opens about two weeks before each race, the race-window precipitation record since 2010, and US 24 and CO 91 status including race-week construction. The facts that don't change: cell service is thin to absent at most crew points, and the afternoon storm climatology is real. Plans that depend on phones or on a dry 2 PM fail here.
