The Western States 100 begins at 5:00 a.m. Pacific Time on a Saturday in late June, starting at the west end of Olympic Valley, California.
You’re here for a straight answer and a plan you can trust. Western States starts early, the start area is busy, and small timing mistakes can snowball into missed moments.
This guide pins down the official start time, explains what “late June” means, and lays out practical timing for runners, crews, and spectators. No guesswork. No fluff.
Start time basics in plain terms
Western States begins at 5:00 a.m. Pacific Time on Saturday of the last full weekend in June, from the west end of Olympic Valley, California. WSER states the 5:00 a.m. start and the “last full weekend” rule in its participant materials. You can read the current wording in the WSER participant guide.
That phrasing matters. Some years, “last Saturday in June” and “Saturday of the last full weekend in June” can land on different dates. If you’re booking flights or lodging, trust the official race calendar and guide language.
Time zone details
In late June, Olympic Valley runs on Pacific Daylight Time (PDT). If you’re traveling from another time zone, set your phone to local time as soon as you arrive. Your brain will try to do mental math at 3:30 a.m., and it won’t be kind.
What the 5 a.m. start feels like
It’s still dark when the race goes off. The air can feel brisk, even when the day later turns hot. If you want a calm start-morning, plan to be parked and walking well before 4:30 a.m. That buffer handles traffic, walking time, restrooms, and last-minute gear checks.
When Does Western States 100 Start? Timing that affects your whole day
The start time isn’t the only thing you need. You also need a realistic flow for race weekend so you’re not reacting to surprises.
Race week timing you can plan around
WSER posts a race-week agenda with check-in, briefings, and official events in Olympic Valley. It’s the easiest way to line up travel days with what you want to attend. Use the WSER race week agenda as your master calendar.
If you can, arrive by Thursday. It gives you room for flight delays, rental car lines, and the “why do I feel off?” travel day. If Thursday won’t work, Friday morning is the next best choice. Late Friday arrivals often turn Saturday into a sprint.
Start-morning checklist for runners
- Wake early enough to eat and digest breakfast.
- Dress for the first hour, not the heat later.
- Stage your first fuel where you can reach it fast.
- Do a fast scan: bib, chip, layers, anti-chafe, salt, soft flask.
- Use the restroom early, then again if you can.
- Get to the start area with time to breathe.
This list looks basic because it is. It also stops the most common start-morning slip-ups.
Start-morning checklist for crew and spectators
- Bring a headlamp or small light for walking and parking lots.
- Pack a warm layer for standing still in the dark.
- Pick a meet spot before the crowd forms.
- Decide your next viewing point before the cannon, not after.
WSER’s spectator guidance is worth a read because access is limited in many places along the route. The official page also notes you can watch the 5:00 a.m. start, and it’s quite dark then. WSER spectator viewing guidance
Start-day logistics that trip people up
Most stress comes from the boring stuff: parking, traffic, and trying to do too many jobs at once. The cleanest plan is to pick one job for start morning and stick to it.
Parking and arrival timing
Olympic Valley has limited road access. Traffic can bunch up before dawn, and it can bunch up again right after the start as people try to reposition. If you’re crew, decide in advance whether you’re staying for the start or leaving early to set up at a later point. Trying to do both often means doing neither well.
Weather reality at 4 a.m.
The most practical move is checking the point forecast for Olympic Valley in the final week, then packing to that. NOAA’s forecast page gives a location-specific view you can refresh daily. NOAA point forecast for Olympic Valley
Pack for contrast: cool air at the start, warmer stretches later. If you’re spectating, a light blanket in the car can feel like a luxury at 4:15 a.m.
Timing rules once the clock starts
Western States runs on a 30-hour limit. The clock begins at 5:00 a.m. Saturday and the final cutoff is 10:59:59 a.m. Sunday. That finish rule shapes pacing, crew plans, and where spectators can catch a runner. WSER lists the finish cutoff in the participant guide.
If you’re spectating, don’t treat pace estimates as a promise. Treat them as a range. Heat, stomach issues, and stops at aid stations can swing timing by hours.
Table: Race-day anchors and practical timing cues
| Anchor | What it is | How to use it |
|---|---|---|
| 5:00 a.m. Saturday | Official start in Olympic Valley (Pacific Time) | Sets every split and every crew ETA |
| 4:00–4:30 a.m. | Common arrival window for parking and walking | Builds in traffic and restroom time |
| Early climb | Fast altitude gain soon after the start | Start steady and stay warm |
| Midday canyons | Warmer, exposed stretches later Saturday | Plan ice, shade, and steady fueling |
| Evening moves | Typical window when crews reposition | Leave time for parking and walking |
| Overnight miles | Fatigue and darkness hit hard | Keep gear simple and crew energy calm |
| 10:59:59 a.m. Sunday | Final finish cutoff | Defines pacing targets and the last push |
| After-finish meet spot | Where you reunite after the line | Stops “where are you?” chaos with dead phones |
These anchors won’t tell you exactly when a runner hits each point. They will keep your planning grounded, which is what you need on a long day.
Travel planning around a 5 a.m. start
A 5:00 a.m. start changes normal travel habits. The most common trap is arriving late Friday, eating heavy, and trying to wake up at 2:30 a.m. sharp. It can work, yet it often feels rough.
Where to stay
Staying near Olympic Valley makes start morning simpler, but rooms fill early. Truckee is a popular backup that can still work if you build in drive time and parking time. If you stay farther out, plan an earlier departure and write it down.
Food and sleep the day before
- Eat your main meal earlier Friday, then keep the evening light.
- Lay out clothes and gear before sunset.
- Set two alarms: phone plus a second device.
- Pack breakfast you already trust.
If you’re crew, match the runner’s rhythm. A groggy crew can turn aid-station stops into a mess.
Time-zone adjustment tips
If you’re flying from the East Coast, the start feels like 8:00 a.m. back home, which sounds friendly. The travel day is the real strain. Shift bedtime earlier in the week by small steps and keep Friday low-stress.
If you can’t see the start in person
You can still catch the race without watching the cannon. The move is to pick one accessible viewing point and commit to it, or follow the event remotely and save your energy for the finish.
Choose one viewing point and stay patient
Pick a single spot that’s clearly listed in the official spectator guidance, then plan a time window. If you chase a runner across several points without a tight plan, traffic can eat your day.
Follow official updates
If you’re at home, start with WSER’s published agenda so you know when race-week activities and updates tend to ramp up. Race-week schedule reference
Countdown plan for a smooth start morning
The best start mornings feel boring. That’s the goal. You lock the plan early, then race week becomes a series of simple steps.
Table: Countdown actions and what they prevent
| When | Action | What it prevents |
|---|---|---|
| 6–8 weeks out | Book lodging close enough to avoid a 3 a.m. panic drive | Start-morning fatigue and traffic stress |
| 2–4 weeks out | Write a simple crew plan with a backup meet spot | Missed handoffs and wasted miles |
| 10–14 days out | Rehearse wake-up and breakfast timing once | Stomach trouble and late departure |
| 1 week out | Check the Olympic Valley point forecast and pack layers | Freezing at the start or overheating later |
| 2–3 days out | Save directions offline and screenshot locations | No-signal navigation problems |
| Friday afternoon | Stage gear, set two alarms, and prep your morning bag | Forgotten items and frantic searching |
| Friday night | Eat earlier, sip fluids steadily, and get in bed early | Waking up wrecked before the start |
| Saturday 3:30–4:00 a.m. | Leave with buffer time and stick to the plan | Missing the start due to traffic |
