The current British record for 100K Women is held by Carolyn Hunter-Rowe with a PB of 7:27:19, which was achieved on August 8, 1993. The current European record for 100K Women is held by Dominika Stelmach with a PB of 7:04:36.

Racing 100k for records, the Project Carbon X 2 event will not be an easy task. HOKA-sponsored ultrarunners Jim Walmsley, Camille Herron, Elov Olsson and Carla Molinaro will be going after individual records in Arizona, while Japanese runners Aiko Kanematsu and Yoshiki Otsuka will be racing the same distance in Chiba, Japan for the 100k world record.

All athletes have been training and planning for the event and individually preparing their race plans. We get an insight into this from XMiles ambassador Carla Molinaro detailing her race day nutrition, you can watch below:

Overall Records: Project Carbon X

At the first Project Carbon X in 2019, HOKA athletes attempted the 100K world record, with some attempting to break six hours. This is a lot faster than the current mark of 6:09:14 (men) and 6:33:11 (women). Along the way, Jim Walmsley set a new 50-mile world record of 4 hours, 50 minutes and 8 seconds, but no-one got close to records for the 100k mark.

Jim Walmsley Project Carbon X 50 Mile World Record

The men’s 100K world record is 6:09:14 (set by Japan’s Nao Kazami in 2018) while the women have a time of 6:33:11, which was set by Japan’s Tomoe Abe in 2000.

Driven by the launch of the new Hoka Carbon X 2 race shoe, on Saturday, January 23 (10pm Sunday, Jan 22nd GMT) the bar will be set again.
