Participation in GO Battle League requires unlocking a GO Battle League set, which grants you access to play a series of 5 matches. Your first set is free, and you can unlock future sets by walking 3 km.

If you do not want to walk, a "Battle Now" button will appear, giving you the option to unlock one set by spending, or  if at least 2 km, 1 km or less than 1 km remaining respectively.

You can view your progress towards earning a set on the Battle page, plus you'll receive an in-app notification and see a red dot on the Main Menu's Battle button when you’ve unlocked a set. Trainers can only unlock a maximum of 5 sets per day, but can still accumulate distance for the future's set.

Ranks and Ratings
Rank is a measure how many matches you've played and/or won. Once you attain a new rank, you cannot drop below it for the rest of the season. Reaching rank 7 can see your rating. Losses do not affect rank but lower matchmaking rating. Ending a season with a higher rank results in better end-of-season rewards.

Only playing the GO Battle League global matching system influences the GO Battle League Rank.

Higher ranks include Pokémon rewarded in lower ranks. The Pokémon are set at level 20 with IV floor of 10/10/10. Snorlax is the first guaranteed and Scraggy is the first encounter in rank 4 if Snorlax has already be encountered.

Development
Battling has been a core part of the Pokémon universe since the very beginning. This new feature that will build upon Trainer Battles, the current form of player vs. player battling that exists within Pokémon GO. Like many Pokémon GO features, GO Battle League will encourage players to get out and explore the world with Pokémon. Trainers will be able to walk in order to earn entry into the GO Battle League, then battle opponents from around the globe through an online matching system and rise in the ranks of the league. This feature should make the Pokémon GO battling experience more competitive and accessible to more Trainers.
