After 13 races on three continents over the course of four months, the World Mountain Running Association wrapped up its 2025 Mountain Running World Cup with two races at different venues on back-to-back days.

Velika Planina Uphill Race

Josphat Kiprotich (Kenya) struck first, but Richard Omaya Atuya (Kenya) ruled late. Omaya Atuya won the 8.5-kilometer climb and its 1,280 meters of gain in 50:21. Kiprotich was second in 51:14, and last week’s Sierre-Zinal winner Philemon Kiriago (Kenya) was third in 52:18. Kenyan runners took four of the top five finish spots.

World Cup women’s leader Scout Adkin (U.K.) was a late scratch from the event, and Susanna Saapunki (Finland) went out hard and dominated in 61:43. She was nearly three minutes up on every other woman. Benedetta Broggi (Italy) edged Kirsty Dickson (U.K.) by a single second for the runner-up spot. Broggi ran 64:32 to Dickson’s 64:33.

Andrea Mayr (Austria) was fourth in 65:03 and pre-race shared that she would not defend her win at the 2023 World Mountain Running Championships Uphill at next month’s event in Spain.

Šmarna Gora

The next day 10k went up 705 meters and down 350 meters for a net uphill course, but this terrain was more in favor to Kiriago. Kiprotich, Kiriago, and Omaya Atuya broke away early but Kiriago moved to the lead late and set a new course record in 40:47. He was 43 seconds better than Omaya Atuya’s year-old former course best. Kirago’s performances over the two days of racing allowed him to move ahead in and win this year’s World Cup.

Kiprotich was second in 40:55 and the day prior’s uphill winner Omaya Atuya was third in 41:07. Kenyan runners took the first five finish spots.

World Cup overall women’s winner Scout Adkin was again out with injury, and Gloria Chebet (Kenya) led all of the women’s race and toward a 49:55 winning time. Valentine Rutto (Kenya) edged Courtney Coppinger (U.S.) for third, 51:02 to 51:09, and uphill legend Mayr doubled back for fourth in 51:49.

Matterhorn Ultraks Extreme – Zermatt, Switzerland

The expert-level race was the year’s 16th Skyrunner World Series contest, and it was run on a 26k course with 3,066 meters of climbing. That’s 16 miles and with 10,060 feet of up. It was all against the backdrop of the Matterhorn and had several glacier crossings on course.

Both William Boffelli (Italy) and Anastasia Rubtsova (Russia) won the race for the third time, and neither was especially challenged.

Frederic Tranchand (France) led the opening climb, but after that, Boffelli took over in the men’s race. He won in 3:25, a full five minutes better than second-place Manuel Merillas (Spain). Lucien Mermillion (France) was a surprise third in 3:31, and early leader Tranchand slid back to fourth in 3:33.

Rubtsova led from the first climb and finished first in 4:14, nearly 10 minutes ahead of the second-place woman. It was a closer race for second, and Maria Christen (Switzerland) edged Lucille Germain (France) by 22 seconds. Both finished in 4:23.

Full results.
