Run 5 du Parc des Collines is a free 5 km run held in Mulhouse's Parc des Collines. It is untimed, takes place on roads, and is intended for those seeking a relaxed outing rather than a competitive race. Team Com organizes this event, founded on the principle of leaving the office to enjoy fresh air and physical activity with others for approximately thirty minutes.
Participants can register individually or as a group with colleagues, neighbors, or friends, making the field more representative of workplace and community participation than serious club racing. Businesses have an additional incentive to encourage participation: the company with the largest team receives the Run trophy. Following the 5 km, an aperitif is provided to all participants, and practitioners from the Pole Sante des Collines lead a recovery session, contributing to the event's atmosphere as a social after-work gathering rather than a typical timed road race.
