La 4 Pattes is a partner race in Metz, Lorraine, with the start village at Les Frigos near the Porte des Allemands. It is run on the first Sunday of September, and the basic rule is simple: two people enter as a team and must cross the finish line together. Adults choose either 6 km or 12 km, while children can join a parent on 1 km or 2 km routes set by age.
