Overview The Summerfest Hole-In-One Challenge is an interactive golf activation on the lakefront at Henry Maier Festival Park during Summerfest 2026, the world's largest music festival. Attendees tee up three shots for $10 and attempt a true hole-in-one, with the first successful shot winning a $5,000 cash prize. Proceeds support First Tee, a nonprofit that builds character and life skills in young people through golf. On site The Challenge runs daily from noon to dusk across the festival, drawing continuous foot traffic and repeat play from the crowd moving along the lakefront. The format keeps participants in the footprint rather than passing through, and the $5,000 prize gives the activation a live stakes moment every time someone steps up to hit. Brand presence The activation is a hands-on platform rather than a signage buy: a partner can attach to the Challenge itself, brand the structure and the prize moment, and put staff and product in front of attendees who are already stopped and engaged. The First Tee tie adds a youth-sport community association to the visibility.
