This Week in Running Justin Mock TWIRHey hey, it’s Memorial Day holiday in the U.S., and that quiets the race volume. It does mark the unofficial start to the Northern Hemisphere summer though, and so I’m queuing up my fave guy Mungo Jerry all day.

MaXi-Race – Annecy, France


In the race’s marquee 88-kilometer distance (55 miles), and on a course that gains 5,000 meters (16,400 feet), Miguel Arsenio (Portugal) toppled the competition and the record books. He squeezed four minutes off the former course best with an 8:40 finish. Arsenio’s on a hot streak. He was second at Transgrancanaria in February to start the year.

Aurélien Dunand-Pallaz (France) and Simon Gosselin (France) followed the race winner in 8:50 and 8:53, respectively.

The women’s race didn’t run as close, and the winner was nearly an hour better than third place. Up front, Fiona Porte (France) dominated in 10:15. She was third in the marathon-distance race here last year. Sandra Sevillano (Spain) was second in 10:47, and Varvara Shikanova (Russia) was third in 11:06.

Only in the final kilometers did Antonio Martínez (Spain) overhaul a fading Robert Pkemoi Matayango (Kenya). Martínez got to the line in 4:00, and Pkemoi Matayango was there 15 seconds later. Anthony Felber (France) nearly caught Pkemoi Matayango too, but was third in 4:01, 17 seconds behind the runner up. The lead group of three was over four minutes ahead of fourth place.

The women’s race ran to the very end too. Anne-Lise Rousset (France) and Ruth Croft (New Zealand) dueled all day and were just over a minute apart at the end. Rousset finished in 4:53 and Croft in 4:54. Anne-Cecile Thevenot (France) was third in 5:04.

World Mountain Running Association U18 World Mountain Running Cup

The MaXi-Race hosted the World Mountain Running Association’s 16th under-18 championships too. The 4.6k race included 100 athletes from 15 countries. Teams included up to four men and four women, and each country’s top three scored.


Oscar Gaitan (Spain) went wire-to-wire for a first-place 17:45. He never got too far in front though and Matthew Edwards (USA) was second just eight seconds back. Just a week ago Edwards won a 3,200-meter Colorado state track title. Randy De Jesus Garcia (Mexico) moved from fifth at the course high point to third at the downhill finish in 18:10.

The U.S. won men’s team gold ahead of Spain and France.

Inés Herault (Spain) ran down climb leader Keeghan Edwards (USA) on the descent and took the women’s individual gold in 20:19. Herault’s expert downhilling placed her well clear of the chase group. Edwards held on to second in 20:46, five seconds ahead of third-place Amelie Lane (England.)

Spain won the women’s team race, one point better than the U.S., while England was third. That left Spain the race’s big winners, taking three of the four potential gold medals.

Full results.
