Western States 100 is five weeks out from its 27 June start in Olympic Valley and the 370-runner field has now hardened into what the WSER board described in a Wednesday newsletter as 'the deepest assembly in 50 editions of the race'. Jim Walmsley confirmed his return through a sponsor entry on 1 May, slotting back into a men's field already led by Kilian Jornet, Hayden Hawks, and 2025 podium finishers François D'haene and Anthony Costa. Jornet has been camped in Foresthill since the start of May and ran his Zegama final tune-up on 17 May before flying directly to California with his family.
The women's field is, if anything, the bigger story. All ten women from the 2025 podium-to-tenth band accepted their automatic entries — the first time WSER has run that sweep without a single decline — and Courtney Dauwalter sits as the line-of-form headline ahead of returning champion Katie Schide, defending titleholder Eszter Csillag and a 2025 Hardrock breakout in Ailsa MacDonald. Hannah Allgood, the surprise Black Canyon 100K winner in February, completes a top five that betting sites have already split 28 per cent on Schide, 24 per cent on Dauwalter and 17 per cent on Csillag with seven days to go.
The lottery picture sits exactly where the board flagged it at December's draw: 254 lottery entrants were drawn from 11,328 names, with the remaining 116 places filled by Top 10 returns, Golden Ticket winners, sponsor entries and a small board-and-foundation allocation. WSER's demographic note from the registration close shows runners from 44 US states (California sending 103, Colorado 30, Oregon 13) and 31 countries, with the US contingent of 288 the largest single-nation cohort in race history. The average chance of getting in for a first-time lottery hopeful was 2.3 per cent — narrower than the rate at the Hardrock and Ultra-Trail Cape Town lotteries this winter.
Race-day logistics are tracking ahead of the comparable point in 2024, with the Foresthill training camp running across 23-25 May and the Robie Point shuttle programme already opened for early bookings. The medical lead, Dr Megan Roche, told Running Lookout that the cooling protocols introduced in 2025 — the Robinson Flat ice-vest station and the expanded Devil's Thumb medical canopy — would be retained for 2026 with the added option of a finish-line ice tub at Placer High School. Weather models are still too far out to call, but the long-range NOAA outlook puts Olympic Valley between 25 and 30 degrees on race day, comfortably inside the historical band.
The five-weeks-out window is also when the live-broadcast picture firms up. UltraSportsLive.TV will once again handle the global feed in partnership with the WSER livestream team, with iRunFar's Bryon Powell and Ellie Greenwood on the lead commentary chair. The North Face has signed on as broadcast title sponsor for the first time, displacing Hoka after a six-year run, and CNN's documentary cameras will be filming inside the Robinson Flat aid station as part of an autumn release on the race's 50th anniversary. Running Lookout will publish weekly previews from now through gun-day, with the elite-field deep dives starting next Friday.
