This Week in Running Justin Mock TWIRArgentina and Australia, Thunderbunny and Hellbender.

It was a global weekend with otherworldly performances, and we’re running it down.

Transvulcania – La Palma, Canary Islands, Spain

Ultramarathon 72k

iRunFar was quick on the earlier race details.

The island traverse went for 45 miles on an up-and-down course that accumulated 14,000 feet of elevation gain.


Ruth Croft (New Zealand) went to the front early and outpaced a competitive chase from three-time winner Ida Nilsson (Sweden, lives in Norway). Croft finished in 8:02 and it was a new course record.

Nilsson edged out Sunmaya Budha (Nepal) for second, as the two ran 8:16 and 8:20. Croft gapped Nilsson and Budha, and Nilsson and Budha, in turn, gapped the rest of the field, too. Nilsson has seven weeks until the Western States 100, where she was seventh a year ago.

The women’s top 10 was:

  1. Ruth Croft (New Zealand) – 8:02
  2. Ida Nilsson (Sweden, lives in Norway) – 8:16
  3. Sunmaya Budha (Nepal) – 8:20
  4. Ekaterina Mityaeva (Andorra) – 8:40
  5. Hannah Allgood (U.S.) – 8:43
  6. Marianne Hogan (Canada) – 8:51
  7. Katharina Hartmuth (Germany) – 8:57
  8. Azara García (Spain) – 9:14
  9. Marina Cugnetto (Italy) – 9:18
  10. Keely Henninger (U.S.) – 9:23

Jon Albon (U.K., lives in Norway) ran away from the men’s chasers on the way to the 50-kilometer high point, and he was out of reach the rest of the way. Albon finished in 7:03, and he too is seven weeks away from the Western States 100. It’ll be his debut for the 100-mile distance.

Dmitry Mityaev (Andorra) and Tom Evans (U.K.) charged late, but when Albon couldn’t be caught, the two finished together in 7:05.

The complete men’s top 10 was:

  • 1. Jon Albon (U.K., lives in Norway) – 7:03
  • T-2. Dmitry Mityaev (Andorra) – 7:05
  • T-2. Tom Evans (U.K.) – 7:05
  • 4. Jeshurun Small (U.S.) – 7:10
  • 5. Ionel Manole (Spain) – 7:19
  • 6. Ben Stout (U.S.) – 7:19
  • 7. Manuel Anguita (Spain) – 7:20
  • 8. Pere Aurell (Spain) – 7:27
  • 9. Antoine Thiriat (France) – 7:39
  • 10. Tobias Geiser (Italy) – 7:39

Marathon 43k

The women’s marathon ran close at the top. Barely three minutes separated women’s one and two Gemma Arenas (Spain) and Ines Astrain (Spain). The pair finished in 4:35 and 4:38, respectively. Kim Schreiber (Germany) was third in 4:44.

And the men’s podium was even more tightly packed. Francisco Jose Anguita (Spain) beat Peter Fraňo (Slovakia) for the win, 3:44 to 3:48, and Milly Dos Santos Lopes (Cape Verde) was only 42 seconds behind Fraňo in third also in 3:48.

Full results.

Ultra-Trail Snowdonia by UTMB – Wales, U.K.

UTS 100 Mile

The event’s longest race went 104 miles with 31,167 feet of elevation gain, and that challenge led to well over half of the 260 starters dropping before the finish. How cool must the rare Northern Lights occurrence overnight have been though, for the fortunate group able to catch sight.

The difficult course greatly spread out the women. Rachel Fawcett (U.K.) won in 34:10, Maria Pijoan (Spain) was second in 39:47, with Corine Kagerer (Switzerland) and Nikki Arthur (U.K.) both finishing in 41:12 for a third-place tie.

Mark Darbyshire (U.K.) was well clear of his chasers in the men’s run. Darbyshire finished in 23:41, and second- and third-place Andy Berry (U.K.) and Michael Dunstan (Australia) came next in 25:18 and 25:45.

UTS 100k

The 64-mile race totaled a burly 20,997 feet of elevation gain. These courses are tough.

Women’s winner Aleksandra Narkowicz (Poland) outpaced the rest of the women by 50 minutes in 16:16. Tess Elias (U.K.) and Georgina Lewis (U.K.) trailed in 17:06 and 17:57, respectively.

Italians Philipp Ausserhofer and Daniel Jung tied for the win in 12:41. Gautier Bonnecarrere (France) was third in 12:55.

UTS 50k

The 34 miler was pretty aggressive too. There were 10,826 feet of elevation gain in this one.

Henriette Albon (Norway) dominated the women’s race. She was nearly an hour ahead of everyone else in 6:39. Twin sisters Lina and Sanna El Kott (Sweden) were next in 7:35 and 7:36, respectively.

It was close, but no one got in under six hours in the men’s race. Brennan Townshend (U.K.) was first in 6:01. Michele Meridio (Italy) and Harry Jones (U.K.) podiumed with 6:08 and 6:11 marks.

Full results.

Valhöll by UTMB – Belgrano, Argentina

The roughly 76-mile mountain run went up and down for 16,473 feet of gain.

The fields were largely from the host country, but Tara Fraga (U.S.) scored the women’s win in 20:12. Belen Barrera (Argentina) and Laura Gordiola (Argentina) were second and third in 20:36 and 20:51.

As with the women’s race, most of the top men’s finishers came from Argentina too. Gabriel Rueda (Argentina) won in 14:27, 10 minutes better than Ludovic Pommeret (France). Sergio Gustavo Pereyra (Argentina) was third in in 14:46.

Full results.

Cocodona 250 Mile – Flagstaff, Arizona

Dang, that was good! The nearly 250-mile race with 40,000 feet of climbing came down to the final miles and hours. iRunFar earlier wrote about the exciting finish.


The 2023 third-placer and 200-mile all-star Mika Thewes pushed to a big lead on the race’s second day and led as late as mile 233 before running into trouble. Rachel Entrekin regained the lead on night three and ran into Flagstaff in 73:31 as the first-place finisher. Entrekin had earlier won a bunch of 100 milers, and totaled 212 miles at the December 2023 Across the Years 48-hour race.

Manu Vilaseca (Brazil, lives in Spain) got past Thewes too and was second in 78:04. Thewes recovered enough to hold onto third in 79:30.

It could be a quick turnaround for Thewes. She’s signed up for the Tahoe 200 Mile in June.

The men left it ’till late too. Harry Subertas ran down longtime leader Jeff Browning in the final miles and finished in 59:50. Browning was second in 60:19, and Arlen Glick was third in 61:46.

As with Thewes, Subertas too is registered for the June Tahoe 200 Mile but he also has both the August Bigfoot 200 Mile and October Moab 240 Mile on his calendar.

It was barely a year ago that Glick was best known for his frequent 12- and 13-hour 100-mile runs, and he’s really changed that up with finishes at the Western States 100, Hardrock 100, Run Rabbit Run 100 Mile, and now the super-long Cocodona 250 Mile.

Full results.

Additional Races and Runs

European Masters Off-Road Running Championships – Madeira, Portugal

I swear, Madeira versus the Canary Islands is one of the best geographic rivalries in trail running. This event had an 8k mountain run, a vertical kilometer race, and a 33k trail run spread across three days.

Barbara Taibon (Austria) won the mountain race in 1:01, with results for the men’s race not yet posted.

The Vertical race was the second of the weekend and Monica Carl (Germany) got to the top first in 46:40. Men’s winner Martin Alvarez-Espinar (Spain) hit the high point in 41:04.

Sunday’s long course saw a small women’s field led by Karen Freitag (Austria) in 3:58 and Shaban Mustafa (Bulgaria) ahead of the men in 2:55.

Rosheen Lord and Matt Houlzet made it around 10 laps of the 10k course faster than anyone else to win the 100k races in 12:53 and 9:46, respectively. Katrina Sawan and Cole Czuchnicki went a little less loopy in winning the 50-mile event in 9:40 and 7:51.

Tiger Claw – Issaquah, Washington

The Tiger Claw 50k has 9,000 feet of climb and features three different ascents and a common descent, and runners get to choose the order in which they tackle the ascents. The Tiger Claw Ascent is a 2.5-mile, 2,500-foot uphill race.

Audrey Lawrence and Andrew Bachman won the 50k in 6:00 and 4:54, respectively. In the Ascent, Ladia Albertson-Junkans and Joseph Gray won in 36:10 and 28:31. It was Gray’s second straight win at the race. Full results.

Jemez Mountain – Los Alamos, New Mexico

The 2024 Jemez Mountain Runs 50 Mile, 50k, and 15 Mile will be remembered for their crazy storms, which brought lightning, rain, and hail, forcing the event to halt the 50 miler and many runners to drop in order to stay safe. Though official results aren’t online as the race organization sorts out the weather-induced chaos, we know that Isabella Poulos and Joshua Mirth won the 50k in 5:55 and 4:53, respectively. We’ll update this as we learn more. Full results (when available).
