In this week’s edition of Singletrack News, controversy erupts around the Ultra-Trail Snowdonia 100K after organizers announced a major course change - which removes roughly 2,000 meters of climbing from the originally advertised route - after the race had already sold out. 

We also discuss the uncertain future of the historic JFK 50 Mile, which could relocate from Washington County, Maryland, for the first time in more than 60 years after the county ended hotel-tax funding that traditionally covered police and medical services. 

Elsewhere, we break down Kilian Jornet’s 2026 season preview, including his plans to race Sierre-Zinal, Western States, and UTMB, and what he said about the training stimulus from last year’s States of Elevation project.

We also cover:

• A chaotic finish at the USATF Half Marathon Championships after lead runners were sent off course
• The Los Angeles Marathon, where the men’s race came down to 0.18 seconds at the line
• Speedgoat by UTMB adding a new uphill race
• Transgrancanaria, where Jon Albon and Henriette Albon claimed victories in brutal weather
• Lotti Brinks and Sean Riedel winning Way Too Cool 50K
• New athlete signings - Hunter Leninger (Only Fans) and Tessa Chesser (Merrell)
• Hayden Hawks’ pivot to Canyons 100K and what it could mean for Western States
• Cirque Series teasing a new championship format
• Prize money across major trail series surpassing €1.15 million

Plus, we share our favorite content from the week, including Francesco Puppi’s latest vlog about his background, training philosophy, and upcoming projects.
