On January 23rd, HOKA® athletes participated in Project Carbon X 2 and attempted to break the 100K World Record in the Carbon X 2, a shoe made with the latest technology innovation from HOKA®.

Now it's your turn!HOKA challenges you to run 100K between February 1st - 28th February to complete the Project Carbon X 2 100K Challenge.


Unique prizes: 20 pairs of the new Carbon X 2 via a competition after the challenge. Positioned as an endurance racer, the Carbon X 2 delivers the same propulsive speed as its predecessor in an adaptable silhouette geared for training and racing alike. Engineered with a responsive, carbon fibre plate and aggressive Meta-Rocker, this performance shoe is a formidable competitor.


At the first Project Carbon X in 2019, HOKA athletes attempted to run 100K (62 miles) in under six hours – far faster than the existing world record. Along the way, Jim Walmsley set a new 50-mile word best of 4 hours, 50 minutes and 8 seconds. Set the bar to impossible, they said; you never know how high you’ll get when you reach for it.

On 23 Jan, a new bar will be set for Project Carbon X 2, when HOKA athletes will again take on the 100K world record wearing this new shoe. The event will have a new look this year, as the world continues to adapt to COVID-19, but you can still join us to watch the event live as athletes across an ocean celebrate movement and compete against each other, the clock, and themselves.
