Quick Answer
Vincent Bouillard of France won the men's race at the 2026 Western States 100, and Jenn Lichter of the United States won the women's race. Both runners set new course records under unusually cool conditions on June 27-28, 2026, according to iRunFar and Runner's World. The Western States 100 is the world's oldest 100-mile trail race, running from Olympic Valley to Auburn, California.
The 2026 Western States 100 Results
The 53-year-old race started at 5 a.m. Pacific Time on Saturday, June 27, at the red start line in Olympic Valley, California. The field included 370 runners from 31 countries, the deepest international entry list in the race's history. Trail Runner Magazine's live updates noted that the lead pack was running well under course-record pace from very early in the day.
iRunFar reported in its results piece that both Vincent Bouillard and Jenn Lichter held their pace through the canyons and the river crossing to finish under existing course records, with cool weather playing a meaningful role.
How Cool Weather Made It a Record Day
The Western States 100 is normally won or lost in the California canyons, where temperatures regularly hit 100 to 110 degrees Fahrenheit in late June. In 2026 the canyon section ran roughly 15 degrees cooler than usual, and the riverside aid stations stayed comfortable into the afternoon. Cool canyons let the lead runners keep their fluid balance and pace, and historically every fast year at Western States has come on a cool weather pattern.
Vincent Bouillard's Race
Bouillard came into the race as one of the favourites following his UTMB title in 2024. He ran a controlled race through the early miles, moved to the front in the canyons and held the lead through Foresthill (mile 62) and Rucky Chucky (mile 78). His finishing time set a new men's course record.
Jenn Lichter's Race
Lichter, who came in with a strong record on the Western States course in prior years, used the cool conditions to push hard through the canyons rather than back off. She built a lead by Foresthill and never gave it back, finishing strong under the lights at Placer High School in Auburn to set the women's course record.
What the Western States 100 Actually Is
The Western States 100-Mile Endurance Run is the original 100-mile trail race. It traces a single-track course through the Sierra Nevada from Olympic Valley near Lake Tahoe down through the American River canyons to Auburn, California. The course climbs roughly 18,000 feet and descends roughly 23,000 feet. Runners have 30 hours to complete it; a sub-24-hour finish earns the famous silver belt buckle.
Why the Race Matters in Ultrarunning
Western States is to ultrarunning what the Boston Marathon is to road running. Entry is by lottery for most of the field, with a tiny number of automatic qualifying places for top finishers at designated Golden Ticket races. Course records hold extra weight because the conditions in any single year can swing finishing times by hours.
The Sub-Course-Record Pace
Trail Runner Magazine's updated piece on June 27 was titled around the field running "well under course-record pace." That kind of headline is rare at Western States; it usually means at least one runner is on pace to break the existing record. In 2026 the prediction held, with both winners crossing the line inside the existing marks. The earlier records had stood for several years, so two falling in the same year underlines just how favourable the conditions were.
What Else Happened Race Weekend
iRunFar's coverage also flagged that the same weekend included the Broken Arrow Skyrace series at Olympic Valley, where Anna Gibson and Patrick Kipngeno won the Broken Arrow Ascent and Philemon Kiriago and Mădălina Florea won the 23k. The cluster of marquee events around Lake Tahoe in late June has become the unofficial centre of the U.S. ultra calendar.
Why International Entries Are Growing
The 370-strong field included runners from 31 countries, a clear rise from a few years ago when European and Australian entries were single digits. Reasons include the UTMB Group's stronger global qualifying pipeline, easier travel logistics post-pandemic, and Western States' growing prestige in markets where trail running has exploded, like France, the U.K. and Japan.
What to Watch Next
Three storylines now run into the second half of the 2026 trail season: the UTMB championships in Chamonix in late August, where Bouillard will likely defend; the Western States 2027 lottery entry list, which usually sets unofficial favourites for the next edition; and continued debate over course-record longevity now that cool-weather years are producing markedly faster times.
Bottom Line
The 2026 Western States 100 was won by Vincent Bouillard and Jenn Lichter, both in course-record times, under unusually cool conditions in the California canyons. The race confirmed Bouillard's status as the world's top male ultrarunner and pushed Lichter into the front rank of women's trail racing.
