Hare A.C.

A Racing

Tracksmith was born out of a passion for racing and the camaraderie of being on a team. These shared experiences - the unforgettable workouts, hard fought victories and inside jokes - enrich our engagement with the sport and heighten our humanity. These are the moments we crave and the reason we return to running over and over again.

Guided by the competitive spirit that all runners share, Hare A.C.’s mission is to inspire and invigorate a passion for racing. Hare A.C. is a global community for runners and provides exclusive benefits, rewards, experiences and innovative race challenges.

Hare A.C. is club, crew and team agnostic. No matter your affiliation, we invite you to join this global community of like-minded athletes.
