How do Gretchen Walsh & Kate Douglass Choose Their Event Lineups for World Cups?

Gretchen Walsh and Kate Douglass have both swept their 3 main individual events at both stops of the 2025 World Cup so far. For Douglass, that has been the 100/200 Breast and 100 Free, while for Walsh, that has been the 50/100 Fly and 100 IM. Being hyper versatile, both athletes have had the luxury of catering their lineups around the World Cup event schedule and seen success heading into the last stop in Toronto.
