This Week in Running Justin Mock TWIRFrom Arkansas to Basque Country, Spain, we’re highlighting the best of the weekend. That means the Golden Trail World Series, the Mountain Running World Cup, and a little bit more too.

You can also check out our race coverage from earlier in the weekend:

Zegama-Aizkorri Marathon – Zegama, Spain

The prestigious race was also the year’s fourth Golden Trail World Series contest. It was the race’s 24th year and it ran as a full marathon, 42 kilometers or 26 miles, through Spain’s Basque Country.

Incredibly popular, the race had almost 12,000 applicants for 225 race spots.

Women

Race veteran Sara Alonso (Spain) took her first Zegama win and led a Spanish women’s group that placed seven runners inside the top 10. Alonso was the daylong leader with a 4:27 finish, but it was close.

Judith Wyder (Switzerland) took second in 4:29, her first appearance at the race, and 2024 runner-up Malen Osa (Spain) overcame recent illness to run a 4:31 for third place.

The women’s top 10 was:

  1. Sara Alonso (Spain) – 4:27:25
  2. Judith Wyder (Switzerland) – 4:29:47
  3. Malen Osa (Spain) – 4:31:18

Men

Second here in 2024, and second at last weekend’s Golden Trail World Series race too, Elhousine Elazzaoui (Morocco) blasted the final downhill to win by over seven minutes. Elazzaoui finished in 3:43 to turn this one into a runaway.

Andreu Blanes (Spain), a former Sierre-Zinal winner, national-class steeplechaser, and world-class orienteer, was the best of the rest in 3:50, and Daniel Pattis (Italy) scored a third-place finish in 3:51.

A week after Kenyan runners took four of the top six men’s Golden Trail World Series finish spots, none raced here.

The men’s top 10 was:

  1. Elhousine Elazzaoui (Morocco) – 3:43:28
  2. Andreu Blanes (Spain) – 3:50:53
  3. Daniel Pattis (Italy) – 3:51:40
  4. Luca Del Pero (Italy) – 3:54:19
  5. Lorenzo Beltrami (Italy) – 3:54:58
  6. Thomas Cardin (France) – 3:55:34
  7. Antonio Martínez Pérez (Spain) – 3:56:42

  9. Stian Angermund (Norway) – 3:59:46
  10. Marcin Kubica (Poland) – 3:59:50

Mountain Running World Cup – Casto, Italy

The Vertical Nasego and Trofeo Nasego doubled up on the weekend and were the year’s second and third races in the Mountain Running World Cup, put on by the World Mountain Running Association.

Vertical Nasego

The all-uphill race ran on Saturday, climbing first on roads before getting increasingly technical higher up. The climb was just 4.2 kilometers in distance and 1,000 meters up.

Women

Andrea Mayr (Austria) had won here five times before and holds the course record, but she was outmatched today.

Second at last weekend’s Golden Trail World Series race, Philaries Kisang (Kenya) scored victory here in 38:55. Last year’s series winner Scout Adkin (U.K.) climbed up in 39:23 for second, and Francesca Ghelfi (Italy) ran 40:40 for third.

Mayr, now aged 45, was fourth in 41:57. Her course record from 2023 stands at 38:06.

Men

A week ago, Philemon Kiriago (Kenya) won the Golden Trail World Series race and Richard Omaya Atuya (Kenya) was sixth. The pair came back for a redo, and Omaya Atuya had the uphill speed.

Omaya Atuya climbed up first in 33:23. That was over a minute better than second-place Kiriago, and it broke Patrick Kipngeno’s former course record. Kiriago got to the top in 34:50, and third-place Andrea Elia (Italy) hit the high point in 34:52.

Trofeo Nasego

The next day’s up-and-down race went almost 21k in distance with a big climb three-fourths of the way through, which was followed by a steep downhill to the finish. Almost all of the top runners came back for the second race of the weekend.

Women

Philaries Kisang and Scout Adkin were at the front for all of it, and Adkin could never quite overtake Kisang. Only six seconds separated the two at the finish, with Kisang winning in 1:46:16 to Adkin’s 1:46:22.

Defending champion Joyce Muthoni Njeru (Kenya) took third in 1:51, and Valenine Jepkoech Rutto (Kenya) and Andrea Mayr ran 1:52 and 1:53 for fourth and fifth, respectively.

Men

Kenyan runners took the top four spots, but the order shifted from the Vertical race. Defending champion Philemon Kiriago was back on top with 1:31 on the clock. He was over two minutes ahead of the next runner, and only 26 seconds separated the second- through fourth-place finishers.

Paul MachokaMichael Selelo Saoli, and vertical race winner Richard Omaya Atuya all ran 1:34. Machoka came in at 1:34:17, and Selelo Saoli and Omaya Atuya had matching 1:34:43 finishes, but with Selelo Saoli taking third.

Fifth-place Luciano Rota (Italy) hit the finish in 1:35.
