The GO Battle League (Japanese: GOバトルリーグ GO Battle League), sometimes shortened to the GBL, is a feature in Pokémon GO which allows for competitive, online trainer battles. This was introduced by Niantic on January 28, 2020. The GO Battle League takes course over a Battle League Season so that the league can provide different tournaments, cups, and rewards each and every season. Only trainers who are above level 10 can participate. In April 2020, the GO Battle League Leaderboard was introduced to show the top 500 trainers in the world. Initially, players got five battle sets per day, and earned one more for each 5 kilometres (3.1 mi) walked. This walking requirement has since been lifted due to the COVID-19 pandemic.
