With the UTMB Mont Blanc festival behind them, ultra and mountain running fans turned to a different set of races for the following weekend, iRunFar reports in its September 7, 2026 This Week in Running roundup. The Vertical Nasego and Trofeo Nasego in Casto, Italy, both counted toward the Mountain Running World Cup, giving the series two stops in a single weekend.
The Vertical Nasego was a steep, short test: 4.2 kilometers covering 1,000 meters of climbing, with nearly half of that elevation gain packed into the final kilometer alone, according to iRunFar. Prize money for the Vertical race totaled 700 Euros for the winner, with payouts extending 15 places deep, a structure iRunFar notes rewards depth of field as much as outright victory.
A Skyrunner World Series race also took place the same weekend, adding to a busy international calendar just days after the UTMB Mont Blanc festival concluded. The clustering of World Cup and World Series events highlights how the sport's competitive calendar continues to layer championship-level racing even in the direct aftermath of one of the year's largest ultra festivals.
Full results and additional race details, including the women's and men's Vertical Nasego outcomes, are covered in iRunFar's complete weekly report. As always, the This Week in Running series serves as a broader digest of race results from around the globe, capturing storylines that might otherwise be overshadowed by marquee events like UTMB.
