RACE DESCRIPTION
The Washington Island Ultra is a race we hold near and dear to our hearts. My wife and I stumbled upon the Island in 2014 and have been passionate about this place ever since. We held the first Washington Island Ultra in 2016 with 25 racers. Since year one, we've welcomed 150 athletes from around the globe to the Island every July. We treat everyone who races with us like family. We're here to help you reach the goal, whatever that may mean for you. My wife home cooks breakfast, lunch and dinner for all 150 athletes every year. We also offer fresh brewed coffee / tea. Finally we bring some fresh brick oven Pizza from Island Pizza - the local pizzeria.
Yes, the event is literally on an Island. Once you drive onto the car ferry and begin the 30min ride over Deaths Door Passage, you start to understand why this event is so special. The island is the definition of peace and quiet. There's just something about this place that resonates with soul. Add on the butter smooth roads, crystal clear water, star packed skies and waterside camping. It's just an incredible racing experience unlike anything else.
We hope you can join us as a solo athlete or with some of your best buddies. We'll put in the work to produce a top notch event so you can come and push your limit in a safe, fun and encouraging atmosphere.
See you on the Island,
- Craig & Maddie Braun

This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
An ultramarathon is anything beyond the standard marathon — 50K, 50-mile, 100K, 100-mile, and timed events. Crossing the line is less about speed and more about not quitting.
From 5K to marathon, running races are an accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
