FatBetty.Run is a vibrant and social running phenomenon that has been uniting runners in the heart of Luxembourg City since September 2017. Founded by a group of four friends, the crew is famous for its fun-loving and inclusive spirit. Their unique name is a tribute to "Fat Betty," the nickname for a notoriously challenging local hill. They host a weekly run every Thursday evening from the Independent Café, offering 5k and 10k options at a social pace, as well as adventurous long runs and trail runs, all with the common goal of having "run fun" together.
