Western States 100 2027 2027: complete FR + EN guide

Western States 100-Mile Endurance Run 2027 preview needs precise planning: 161 km, 5500 m of climbing and logistics centred on Olympic Valley, Truckee, Tahoe City, Auburn and Sacramento. Western States runs from Olympic Valley to Auburn on the historic pioneer route: an early climb to altitude, long forest sections, very hot canyons, quad-breaking descents and a runnable finish to Placer High School. The 2027 preview is mainly about lottery timing, crew planning and heat management.

Race overview

Western States 100 2027 is part of the Week 29 TrailCompanion guide batch. This page condenses the practical decisions to make before booking: reference format, terrain, access, lodging, gear and official links to check before travel.

The key is not distance alone. On this kind of trail, success depends on pacing the climbing, managing aid stations, adapting to local weather and arriving rested with a simple bib, start and post-race plan.

What you actually need to prepare

Build preparation around hilly long runs, controlled descents and hike-run blocks. For 161 km, you need to hike early without losing rhythm, run the easier sections and eat before intensity shuts down appetite.

TrailCompanion Prep then turns the guide into a checklist: tested kit, lodging, transport, documents and week-by-week nutrition reminders.

Western States 100 2027 mandatory / recommended gear

The official organiser list always comes first. This baseline covers the realistic needs to prepare your pack before bib control.

Heat management first: cap, sunglasses, sunscreen, possible ice bandana and enough water capacity for the canyons.
Reliable headlamp and backup for the second half if your race time extends beyond one full day.
Stable vest with flasks, tested food, electrolytes, cup if required and a small blister kit.
Shoes that can handle long descents, dust, heat and a runnable finish after 120 km.
Written crew/pacer plan: bags, dry clothes, charging, cooling and simple instructions by aid station.

Recheck the official rules during race week: weather, timing and gear requirements can change.

Logistics to solve early

Start logistics from Olympic Valley, Truckee, Tahoe City, Auburn and Sacramento. Confirm bib pickup, parking or shuttles first, then choose lodging. An early start or late return can completely change the best base.

Keep the official links in your Prep: race website, registration page, rules, access map and last-minute instructions. This guide gives the framework, but the organiser remains the final source.

Transport to Olympic Valley, Truckee, Tahoe City, Auburn and Sacramento

Sacramento is the simplest airport for the Auburn finish; Reno works well for Truckee, Lake Tahoe and Olympic Valley before the start. Most runners plan around a car or motorised crew.

The race is point to point. Decide early where to sleep before the start and after the finish, then confirm crew access, parking, any shuttles and roads to authorised aid stations.

Where to stay for Western States 100 2027

Olympic Valley, Palisades Tahoe, Truckee and Tahoe City are the most practical start bases, but rooms disappear quickly once lottery entrants are confirmed.

Auburn or Roseville simplify post-race logistics. For a crew, two separate lodging zones can be more practical than one central base.
