It’s Official. Project Carbon X 2 Is Coming.

Updated: Jul 28

Note: We'll have a LIVE INTERVIEW with Jim Walmsley on Instagram on Sunday at 8pm EST. Tune into the Chaski Account or watch out for the replay.

On January 23, 2021, a small group of elite HOKA ONE ONE athletes will attempt to once again break records at 100km (62.2 miles) on a fast road loop at an undisclosed location in the US. This event celebrates the launch of HOKA’s Carbon X 2 racing shoe and builds on the success of the May, 2019 event which saw Jim Walmsley run the fastest 50 mile time in history.

Walmsley once again headlines the 2021 event as he chases the 100km world record of 6:09:14 (a pace of 5:56 per mile) by Nao Kazami of Japan but will face challenges from the likes of Hayden Hawks (2020 JFK 50 Mile Champ and CR holder) and a slew of both experienced veterans and up-and-comers in the ultra world.

Newly signed HOKA pro, Camille Herron (100 mile WR holder, 24 hour WR holder), headlines the women’s field and will be chased by Chaski’s own Devon Yanko, who’s been having a fantastic year, despite not having any real races in which to compete.

The event will be professionally live-streamed for free from HOKA with commentary from Toni Reavis, Carrie Tollefson, and Eric Senseman. The entire race will be accompanied by a second event happening in Japan with a full elite field of both men and women competing over 100km as well.

Team Chaski is well represented, with four of our coaches competing and several others serving as pacers. We caught up with a few of them below and will feature more interviews in the weeks leading up to it.

The entire elite athlete field for the US event is at the bottom of this page.

Devon Yanko - 100km PR: 7:46, 50 mile PR: 5:59

Training has been super solid. I ran more miles in 2020 than any previous year and stayed healthy. Most recently, I ran a 3:15;39 50km time trial, which would be the 3rd fastest American Women's time ever, had it been a real race. But super confidence-building that I could do that in this lead-up.

My goals for the race are to run smart, run my plan, run a huge PR and compete as best I can.
