Cross Banana Fit is a January cross-country race series held at the Décathlon Village in Wittenheim, Alsace, France. Organized by Team Com, it features four races for adults and children, ranging from 800 metres to 6.5 km, accommodating young runners, casual participants, and competitive club athletes.
The course consists of loops around the lake behind the Décathlon store, providing a compact layout for spectators and families. Over 200 athletes participated in the initial edition, aligning with the post-holiday running season as people resume training at the year's start. Joseph Schiro and Isabelle Paurisse, both of Entente Haute Alsace, won the inaugural elite men's and women's races, and the event has continued through subsequent editions, adopting a Saturday afternoon schedule.
