Embark on an extraordinary ultra-running challenge at Six Days in the Dome, held on June 27, 2026, at the iconic Pettit National Ice Center in Milwaukee, WI. This world-class event features demanding 24-hour and 12-hour races, drawing athletes from across the globe eager to test their limits and chase records. Unlike traditional outdoor races, Six Days in the Dome offers a unique, fully climate-controlled environment, providing optimal conditions for peak performance year-round.

The course is a flat, USATF-certified 443.45-meter indoor oval, featuring a slightly cushioned Regupol Kombi surface that encircles the facility's ice rinks. While typical outdoor conditions in Milwaukee in late June might bring highs around 80F and lows around 62F with a 16% chance of precipitation, runners inside the Dome benefit from a consistent 50-55 degree Fahrenheit temperature and 30-35% humidity, eliminating environmental variables. The repetitive nature of the loops and the hard surface demand immense mental fortitude and strategic pacing. Runners change direction every six hours to balance the strain, and aid stations are conveniently located trackside, offering continuous support and regular meals.

Six Days in the Dome is more than just a race; it's a profound exploration of endurance, strategy, and mental toughness. Athletes embrace a "go as you please" format, managing sleep, fueling, and body care in short bursts to maximize their efforts. This esteemed event is a proven venue for shattering personal bests, setting national records, and even qualifying for national teams, all within an atmosphere of camaraderie and shared determination.
