Welcome to the world's largest cross-country race – TCS Lidingöloppet! The race is known to be as challenging as it is varied. The tough and beautiful course is one of Sweden's great running challenges, a true test of strength for all participants – elite as well as recreational runners. Here, flat meadows and dirt roads alternate with sloping paths and steep hills. During the weekend there is a race for everyone with different age groups and course lengths – from 1.7 to 30 km.
