This Week In Running: August 9, 2021

This Week In Running’s trail and ultra recap for August 9, 2021.

By on August 9, 2021 | Comments

This Week in Running Justin Mock TWIRIt was another blockbuster summer weekend. Sierre-Zinal in Switzerland was among the brightest highlights, but there were USATF trail national championships here in the U.S, a Skyrunner World Series contest in Norway, and at least one ultrarunner in the Olympic Marathon too. We’re talking about all of it!

Sierre-Zinal – Zinal, Switzerland

Sierre-Zinal celebrated its 48th year, running among five peaks that top 4,000 meters each on a 31k course that connects the two Swiss mountain towns. The race was part of both the Golden Trail World Series and the World Mountain Running Association’s (WMRA) World Cup, and it was definitely one of the year’s most competitive trail contests.


Maude Mathys (Switzerland) is favored in most any race she enters, especially at Sierre-Zinal where she was already a two-time winner and course-record holder. As expected, Mathys earned her third-straight Sierre-Zinal win, doing a pair of handstands while smiling as she reached the finish. This year’s 2:46 run bettered her own course-record time, but happened on a slightly different track. The women’s race started 15 minutes before the men, and Mathys was fast enough to finish ahead of the first man. This week’s win also marked a quick return to form. Mathys was just third at last weekend’s Thyon-Dixence race when she suffered from heart palpitations.

(In 2015, 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.)

Surprise second-place finisher Nienke Brinkman (Netherlands) came through in 2:48. She won the Zermatt Marathon earlier this year. Anaïs Sabré (France) was third in 2:55.

The rest of the top 10 included:

4 – Blandine L’Hirondel (France) – 2:59
5 – Teresiah Omosa (Kenya) – 2:59
6 – Marcela Vašínová (Czech Republic) – 3:03
7 – Simone Troxler (Switzerland) – 3:05
8 – Núria Gil (Spain) – 3:07
9 – Alice Gaggi (Italy) – 3:07
10 – Judith Wyder (Switzerland) – 3:08

The top Americans in the field were Katie Schide (living in France) and Brittany Charboneau. They finished 19th and 20th in 3:17 and 3:18, respectively.

Just like Mathys, Kilian Jornet (Spain, living in Norway) surprised no one, winning the race for an incredible ninth time. He finished in 2:31. Robbie Simpson (U.K.) overcame an early side stitch and rallied in the second half for a second-place 2:32. Simpson rocketed from as far back as 12th to his runner-up position. Cesare Maestri (Italy) was third in 2:33.

The men’s top 10 included:

4 – Lengen Lolkurraru (Kenya) – 2:34
5 – Davide Magnini (Italy) – 2:34
6 – Thibaut Baronian (France) – 2:34
7 – Dani Osanz (Spain) – 2:35
8 – Julien Rancon (France) – 2:36
9 – Rémi Bonnet (Switzerland) – 2:37
10 – Hayden Hawks (USA) – 2:37

Full results.

The next Golden Trail World Series race is the September 4 Chiemgau Trail Run in Germany. The next WMRA World Cup race is the August 15 Krkonosky Half Marathon in the Czech Republic.

Ragged 50k – Sunapee, New Hampshire

The Ragged 50k runs point-to-point on technical trails with 6,300 feet of elevation gain toward the finish at Ragged Mountain in New Hampshire. The race was the USATF 50k Trail National Championships, had a $5,500 cash purse, and it all happened on a brutally hot and humid day. Official results aren’t yet posted, but social media reports have revealed the winners.


Kimber Mattox is a former U.S. Mountain Running Team member, and she’s registered for next weekend’s national team selection race, but this weekend she went long. Mattox won the 50k race, and Britta Clark was the second-place woman. Abby Levene rounded out the women’s podium in third place.

David Sinclair races often, and usually comes out on top or close to it. Two weekends ago he was second at the Speedgoat 50k and he’s raced at least four ultramarathons this year with a few more on the calendar too. Sinclair won the 50k race here, just like he did in 2019. According to social media, Ben Robinson took second, and Philip Royer third.

Full results (when available).

The next USATF mountain, ultra, and trail national championships is next weekend’s August 15 USATF Mountain Runnings Championships in Oregon. The race happens at the up and down Gnar Gnar Mountain Race.

Tromsø Skyrace – Tromsø, Norway

This year’s Tromsø Skyrace didn’t have it’s typically world-class competition, losing some of those top runners to Sierre-Zinal, but the 57k race was still part of the Skyrunner World Series.


Therese Årvik (Norway) triumphed in a close women’s race against Ruut Uusitalo (Finland). The pair gapped the field with 9:45 and 9:52 breakaway runs. Jessica Asensio (Spain) was a distant third in 11:17.


Lars Olaf Haaheim won for his home country in 8:17. Fredrik Eliasson (Sweden) and Erland Eldrup (Norway) were second and third in 8:29 and 8:35.

Full results.
