By on May 12, 2025 | Comments

Transvulcania and Cocodona were the week’s high spots, but that’s just the start of another big rundown. Read up on the Skyrunner World Series in Türkiye, the Ice Age Trail in Wisconsin, and a U.S. 24-hour national team qualifying spot in Pennsylvania.

Transvulcania – La Palma, Canary Islands, Spain

Ultramaratón 73k

The event’s classic distance went 45 miles in, at times, wild weather with heavy rain and wind. After three second-place finishes, Anne-Lise Rousset Séguret (France) moved past defending champion and course record holder Ruth Croft (New Zealand) near halfway and rolled to a first-place 8:18. Croft dropped from the race with hypothermia, and no one finished within 18 minutes of race winner Rousset Séguret.

Second-place Ekaterina Mityaeva (Neutral) stalled enough late that Martina Valmassoi (Italy) made big time jumps and finished only 27 seconds behind Mityaeva. The pair came in at 8:36 and 8:37, respectively.

  5. Giulia Marchesoni (Italy) – 9:00

For the men, Peter Fraňo (Slovakia) has quietly moved up the international ranks in recent years and scored a big win here. He finished in 6:55 after a late-race duel with Andreas Reiterer (Italy). The two were only three minutes apart with second-place Reiterer in at 6:58. Fraňo makes his 100-mile debut in June at the Western States 100.

Manuel Anguita (Spain) was a distant third in 7:19.

[In 2015, Maude Mathys received a warning without suspension from the Disciplinary Chamber for Doping Cases of Swiss Olympic for two positive tests for clomifene (previously clomiphene) after it was determined that she was mistakenly taking the drug without first obtaining a World Anti-Doping Agency Therapeutic Use Exemption.]

Skyrunning phenom Luca Del Pero (Italy) beat out Sergio Alvarez (Spain) for the men’s win. Both finished in 2:11 with Del Pero 12 seconds in the lead. Daniel Osanz (Spain) was third in 2:12, 61 seconds behind the runner-up.

Cocodona 250 Mile – Black Canyon City, Arizona

Cocodona 250 Mile

Both course records fell on the 256-mile one-way adventure through Arizona. Runners had up to 125 hours to finish the epic, but Rachel Entrekin and Dan Green did it in 63:50 and 58:47. For Entrekin, it was a repeat win, her second in the event’s five-year history, and Green did it in his first go at anything longer than 100 miles.

Entrekin gained the lead just after 100 miles when early leader Courtney Dauwalter stopped and her 63:50 finish was over seven hours better than Annie Hughes’s event record that had stood since 2022.

Green’s run topped Joe McConaughy’s former event best from 2022.
