The Indiana Fever's Gainbridge Fieldhouse buzzes with anticipation before games, largely due to Caitlin Clark's captivating pre-game routine. Fans, like Debbie Elson, vie for prime spots to witness Clark's warmup, with hundreds lining up hours before doors open for a chance at an autograph. Clark's walk-ins and outfits have become viral sensations, adding to the spectacle.

Clark's warmup on the court is a critical part of her preparation, a 90-minute "activation" process. Approximately 1,000 fans observe as she practices 3-pointers and drives, often simulating physical play with assistant coach Austin Kelly. This intense preparation is vital as she returns from injury and faces the physicality of the WNBA. Kelly notes they work on her being "balanced when she is unbalanced."

Clark's impact extends beyond the court; she has revitalized attendance for the Fever, increasing it from 4,000 to 16,560 fans per game by 2025. Analyst Debbie Antonelli coined the term "Clarkonomics" to describe her profound influence on the league's statistics and popularity. Even after games, Clark often stops to sign autographs, with one count reaching 108 on a road trip, demonstrating her dedication to her fans.
