Jim Walmsley is back on the Western States 100 start list. The four-time champion and course-record holder confirmed on 1 May that he will toe the line in Olympic Valley on 27 June, taking one of the sponsor entries reserved by Hoka after withdrawing from the 2025 race on the eve of the start with an injury that derailed his entire summer. The announcement, made through his sponsor's social channels and quickly relayed by the trail-running media, immediately reshaped the favourite's column for the most prestigious 100-miler on the calendar.
Walmsley's path back to the Olympic Valley start has been deliberate. He chose not to chase a Golden Ticket through the spring qualifying series, an approach he has previously used to arrive in California with fresh legs. His sponsor entry sits inside Hoka's allocation of four bibs, with one going to Walmsley, one to Tommie Runz, and two to amateur women selected through the brand's community programme. The decision to wait for a sponsor spot rather than race a hard 100k qualifier in March or April matches the way he prepared for his record-setting wins in 2018, 2019 and 2022, when he favoured a long uninterrupted block of Coconino Cowboys training over additional race sharpening.
His return changes the shape of a men's field that, even before the announcement, was the deepest in years. Defending champion Caleb Olson sits at the top of the form table after his 14:11:25 in 2025, the second-fastest finish in race history, with last year's runner-up Chris Myers (14:17:39) and a cluster of Golden Ticket winners — Daniel Jones, Jeff Mogavero, Seth Ruhling, Hans Troyer, Hiroki Kai, Ryan Montgomery — all returning from top-10 finishes. Kilian Jornet, taking on Western States for the first time since his 2017 win, is the other obvious story line. Walmsley pushes that group from a stacked race to a historically loaded one.
The sport-political reading is harder to ignore. Walmsley still owns the Western States course record at 14:09:28, set in 2019, and his win in 2022 broke 14:10 again. Olson came within two minutes of him last year on a hot day. If Walmsley arrives sharp, the prospect of the first sub-14-hour men's run sits within the realm of plausibility, particularly after the heat-acclimation protocols that the leading American contenders have built into their spring blocks. If he arrives cautious, the more interesting question is whether Olson and Jornet can turn the late stages into a tactical contest of the sort Western States has rarely produced.
For Walmsley, the bigger frame is fitness, not legacy. He has been open about how the 2025 withdrawal affected him — a season cut short before it began — and the build-up since has been steady rather than spectacular, with quiet weeks at altitude in Flagstaff and a public profile that has been markedly lower than during his European seasons in 2023 and 2024. Whether that translates into a fifth Western States win or a return to the front of the American 100-mile scene more broadly will depend on how the body holds up over the next six weeks. The race, in any case, has its biggest name back at the start line.
