Junior World Orienteering Championships

The Junior World Orienteering Championships, known as JWOC, are an annual orienteering competition first held in 1990 as an official championship. Entry is open to national teams of competitors aged 20 and below as of 31 December in the year of competition, and the representative countries must be members of the International Orienteering Federation. Before 1990 an international junior match was arranged in 1983 in Ry, Denmark, then in 1984 and 1985, and from 1986 the events were the unofficial Junior European Championships. The programme began with an individual classic race and a relay, gained a short distance in 1991 that became the middle distance in 2004, added a sprint in 2006, and since 2022 includes a sprint relay with four runners in each team, two women and two men.
