The timed-research quest “Spring Marathon Timed Research” asks trainers to explore 42 km, rewarding 21,000 XP and a Marathon Visor Pikachu. All participants receive a Spring Marathon GO Pass. Tier 1 grants 2× XP for PokéStop spins (3× with GO Pass Deluxe); Tier 2 halves egg-hatch distance. GO Pass Deluxe costs US$4.99, while a Deluxe + 6 Ranks upgrade costs US$6.99 and ensures enough GO Points for Rank 7. Any 5 km egg hatched during the event can contain the new Pokémon.
