Hoka One One has launched the Carbon X, a shoe that combines high cushioning with low weight for ultrarunning. To promote the shoe, the company held Project Carbon X, a 110K race in California, from Folsom to Sacramento, on May 4. Several of the brand's athletes took part in the race. The winner among the men was Hideaki Yamauchi, the current IAAF 100K World Champion, at 6:19:54, more than ten minutes shy of the record. Hoka's women athletes failed to break any records, but they did finish first.
