This Week In Running: April 16, 2018

This Week In Running’s trail and ultra recap for April 16, 2018.

This Week in Running Justin Mock TWIRThis week’s highlights include the year’s final Western States 100 Golden Ticket race–the Lake Sonoma 50 Mile–and the Ultra-Trail World Tour’s latest–the Marathon des Sables stage race. Adding to that though, we have tons of results from across the USA. It’s Monday, let’s get newsy.

Lake Sonoma 50 Mile – Healdsburg, California

Julbo Resist

Thanks to Julbo for sponsoring this edition of TWIR!

Did you miss the Lake Sonoma 50 Mile and need to catch up?  No worries, iRunFar was there and delivered a whole bunch of coverage. Early last week there was a race preview, and then pre-race interviews, of course there were in-race Twitter reports, and then the usual post-race report and interviews. Whew! Deeper coverage takes the results 10 deep.


Up, up, and away, Keely Henninger is rising fast. She caught attention in March with a win at the Chuckanut 50k against a strong field, and then here won in dominant, start-to-finish fashion. Henninger ran 7:13, coming within five minutes of Stephanie Violett‘s 2015 course best. Henninger’s time ranks second-fastest ever here. She did however turn down her Golden Ticket entry to the Western States 100 in lieu of racing the Lavaredo Ultra Trail in Italy that same weekend in June.

Taylor Nowlin and Camelia Mayfield were second and third and did accept their Golden Tickets. The two chasers were just over a minute apart with 7:44 and 7:45 finish times.

Mama, there goes that man! Course records keep coming for Jim Walmsley. He won the race and broke his own 2016 course record with a 5:51 finish, nine minutes better than before. Given what’s he’s done over the past two-plus years, it’s easy to overlook just how fast this is and to take Walmsley’s success for granted. Let’s lay it out there versus some other well-known runners for perspective. In 2017 Sage Canaday won in 6:17, and Zach Miller and Rob Krar ran 6:11 and 6:12 in 2014. Whew, the Walmsley train is back on the tracks and gaining speed.

Eager to return to Western States, Jared Hazen was second in 6:18, and Mario Mendoza was third in 6:25.

With both Walmsley and Mendoza already holding entries into Western States, the second Golden Ticket fell to a particularly determined Eric Senseman. He was fourth in 6:33. His Golden Ticket gives the Coconino Cowboys five entrants there and it must be mission accomplished for that group.

Full results.

Marathon Des Sables – Ouarzazate, Morocco

This was the 33rd year for the 250-kilometer, week-long Marathon des Sables stage race across the Sahara Desert.


Magdalena Boulet (USA) became the third American woman to win here in the last five years. Following the five competitive stages of racing (a sixth non-competitive stage follows at the end of the week), Boulet was way out front in 25:11.

Bouchra Eriksen (Denmark) and Gemma Game (U.K.) were second and third in 26:36 and 27:00. Past winner Natalia Sedykh (Russia) and Anna Marie Watson (U.K.) totaled 28:26 and 29:04 to finish fourth and fifth, respectively.


It’s a dynasty. Rachid El Morabity (Morocco) and brother Mohamed El Morabity (Morocco) finished first and second, again. The two finished the five competitive stages in 19:35 and 20:01. This makes it six Marathon des Sables wins for Rachid, an absolute dominance for him in his home region.

Third place was perhaps a surprise however. Robert Merile (France) finished in 20:41 to edge Abdelkader El Mouaziz (Morocco) by 10 minutes. Fifth-place Gediminas Grinius (Lithuania) totaled 21:31 through five stages.

Full results.

The next Ultra-Trail World Tour race is the April 28 Madeira Island Ultra-Trail 115k.

She ran 30:49. Men’s winner Scott Coles won in 28:09. Compare those finish times to 2017 when the race winners ran 22:34 and 19:42. Full results.

[Editor’s Note: We spend hours weekly creating this column, often ahead of races publishing results–by combing social media. We can’t cover all trail/ultra races taking place each week, so we try to provide results of the most competitive and a spectrum of other events from around the world.
