About the Event

The Six Days in the Dome returns to Milwaukee, Wisconsin from June 22nd through June 28th, offering a range of ultramarathon events for athletes seeking endurance challenges on an impressive scale. This year’s event will kick off with the grand 10-Day race starting Thursday, June 18th at 10:00 AM and concluding on Sunday, June 28th. The Six Days in the Dome also features a series of fixed-time races such as the invitational 24-Hour race for elite athletes who are aiming to set records or qualify for national teams.
The event unfolds within the expansive expanse of Milwaukee’s South Side, where runners will circle around tracks that feel like extensions of the city itself. The early summer light casts long shadows across the streets and parks nearby as participants prepare to push their limits in a setting both familiar and challenging. Each day brings with it the changing hues of dawn breaking over the city skyline and dusk settling into cool breezes, creating an atmosphere thick with anticipation.
Established by Bill Schultz and Mike Melton since its inception several years ago, Six Days in the Dome has become a hallmark event for ultrarunners looking to test their mettle against some of the toughest courses around. Over the past few editions, it’s attracted hundreds of participants who come together not just to compete but also to support one another through grueling hours and days on end. The race honors those dedicated athletes whose performances inspire others year after year. It's about more than setting personal bests; it's about community spirit and shared experiences that define the essence of these races in Milwaukee.
The Six Days in the Dome primarily takes place at a large indoor facility where runners will navigate an oval track designed for endurance racing. The venue is known for its consistent surface, making each lap feel familiar yet demanding as fatigue sets in over time. Distances vary from 12-hour spurts to full 72-hour marathons and the prestigious Invitational 24-Hour race specifically for elite athletes. Start lines are clearly marked with banners identifying different categories of events, while finish lines offer a sense of accomplishment at regular intervals throughout each day’s competition.
Each fixed-time event is consolidated across all days in terms of results to provide fair comparisons among participants regardless of when they start their challenge. Aid stations dot the track every few miles, offering water, sports drinks, and energy snacks essential for maintaining stamina over long hours. The course itself features no major elevation changes but requires mental fortitude as much as physical endurance.
Runners can expect temperatures around 20°C with an average wind speed of about 13 km/h during the event period in June. Humidity levels hover at a comfortable 67%, making conditions ideal for sustained efforts without overheating concerns. The trail surface remains hard and dry, providing reliable footing even as night falls or early morning fog clears. With UV index reaching very high values, protective gear like sunscreen and sunglasses becomes crucial.
