Pokémon Go ‘Spring Marathon’ event guide
Pokémon Go is hosting a Spring Marathon event running from May 12-18, introducing new Pokémon species Flittle and Espartha to the game alongside a special costumed Pikachu variant. The event continues the game’s recent trend of releasing themed Go Passes—a premium feature tied to specific gameplay activities—with this edition focused on walking and movement mechanics.
The Spring Marathon Go Pass provides multiple encounters with Flittle at different progression tiers. Players can obtain Flittle encounters through the basic event Go Pass at rank 19, rank 30, and rank 60, offering progression-based rewards throughout the event period. Additional bonuses are tied to the event’s emphasis on active play and walking, encouraging players to stay mobile to maximize rewards.
The event demonstrates Pokémon Go’s ongoing live-service model, using limited-time seasonal events to drive engagement and monetize through optional Go Pass purchases. The inclusion of newly available Pokémon species creates urgency for players to participate during the event window. This Spring Marathon follows Pokémon Go’s established pattern of monthly themed events that refresh the game’s content rotation and provide exclusive creatures and cosmetics unavailable during other periods.
