Washington island ultra

experience washington island

Craig Braun | Race Director

The Washington Island Ultra is one of those events that just resonates with the soul. The drive north, through Door County is one of my favorites. It's a beautiful drive & I know what's waiting for me at the tip of the state. Arriving to Northport, driving onto the ferry ...you enter into a whole new world. I can't explain it, but something changes in your heart. It's relaxing, it's exciting, it's the realization that this is happening and holy sh*t you're racing an ultra triathlon on an Island.

The people of this event make it what it is. The butter smooth roads, crystal clear water, and star packed night skies are all just extra cherries on top. Of all the events I've ever raced or directed, there's just something special about this place and I hope everyone who wishes to experience Washington Island does get the chance to do so.


I look forward to serving you on race week and can't wait to watch y'all find your limit, and then go a few more miles.
See you on the Island,

Due to the popularity of this race, beginning after the 2021 event, we'll be adopting a lottery system along with a priority registration for any athlete who has raced the event in the previous three years.

Priority Registration
All athletes who have completed on the island in the three previous years of the event will receive a reserved registration link to the email that was used during registration. This link will be sent out on the third Thursday of August and will remain active for one week, or, until we hit 140 registered athletes. If you have raced in the last three years and lost your registration link, please click here.

40 lottery spots are selected each year to allow new athletes the chance to race on this beautiful Island. In order to enter the race lottery, we require a $10 donation be made to the park and rec department of Washnigton Island. Your entires never expire, and you're allowed to enter your name in the lottery year after year. If you've entered the lottery three times, then there are three tickets in the drawing with your name on it. If you've only entered the lottery once, there is one ticket with your name on it. Lottery selections will be made on September 1st and those who have been selected will recieve a reserved registration link in their inbox and text message by 10am EST on 9/1. If selected, you have 72 hours to claim your spot. If you do not claim your spot within the 72 hours, you forfiet your position in the lottery and all tickets are removed. If you are wishing to create a team, and your name is selected, you are allowed to invite up to 4 additional team members to register and join the event. Upon accepting your invitatoin, any lottery tickets held by that team member will be removed from the lottery pool. We will continue to make lottery selections every three days until the 40 lottery positions are full. Charity Entry We reserve 5 spots each year for anyone who would like a guaranteed entry into the Island by raising $1,000.00 for the Washington Island Parks and Recreation department. It's been a goal of this event to help uplift and support the beautiful recreation areas on Washington Island. We've fallen in love with this place, and we're excited about helping imporve and maintain the many parks on this island for thousands of visitors to enjoy each year. You may claim a charity entry by emaling us here. Training Camp Entry We reserve 15 spots each year for anyone who has joined us at either our Spring or Fall Mammoth Training Camp. All athletes are given the option to claim a entry into the Island. For information on our Spring camp, that takes place on Washington Island, WI - click here.

SOLO ATHLETES are allowed to have crew and support during the race. Crew is allowed to stay in your campsite, but we do not make more space available based on the amount of crew you have coming along. We will have a space at the transition area for you to place bottles / fuel so you won't have to go back to your tent lap after lap to refuel. Your crew is allowed to provide supprt inside the fenced in transition area lap after lap. You are allowed a pacer on the run and bike. If a pacer is accompanying you, they must check in at the timing tent and are requried have a wristband on before entering the course.

TEAMS will have only one team member on course at a time. Upon completion of a team members lap, another team member may begin. Completion of lap happens when that team member reaches the triple cone in the transition area and yells your team number to our timer. You do not share a bib number, but rather all team members will have their own wristband with your team number on it - making transition fast and easy. Teams can privde support to their team memebrs inside the transition area, but may not utilize the solo tables for storing extra bottles / fuel.

In the winter of 2013, I myself in deep pit of anxiety and depression - a slump if you will. I was desperate to crawl my way out of this funk and get back on track with training and life. So, I went looking for a place to reset, be quiet and reasess my life, my goals, my everything. I hadn't been to Door County but it seemed like a place that was pretty quiet, especially in the winter seasons, so I packed a bag and headed as north as I could. Little did I know I'd have to get on a car ferry to an island... When I arrived, I went for a beer, grabbed some food and stumbled into a gentleman name Herb (he called himself Gibson). He told me he owned a West Harbor Resort and I needed a place to stay so it sounded good to me. I don't know if Herb remembers stumbling into me, but that night changede my life forever as he sat up with me and chatted away like old friends. I woke up the next morning, drove sarund the Island for a bit and headed home. Easy as that - I was out of my funk, thanks to Herb. The following year, My wife and had a weekend away from our son, Leo Gibson Braun (catch that middle name?), so we headed to the Island since I talked to mich abouot it. We decided to skip the car and rented some bikes on once we goot off the ferry. We rode around, found more lovely people on called this place home and cruised along butter smooth roads to places like Schoolhouse Beach, Island Cafe, Red Cup, Albatross, Gislasons, Sand Dunes and so many more wonderfull places. We caught the last ferry back and it was then I decided, I need to be a part of this place - I need to bring a race here. Our first year was 2015. We had a whopping 30ish people racing. It was a treasured first year and one we'll never forget. The second year, we had 150, the third 200 and it's been set at 200 participants ever since. The


Our Village is located at Gislason Beach and is a large grass area where we setup camp for a few days. There is a beautiful view of the water and a large red barn area for shelter in case we experience weather. We have a designated sleeping tent area, and a designated pop up / hangout area in the village. The sleeping area is located near the rear of the village. We ask to please respect both areas and use the sleeping area to sleep, and change clothes only. During the night, please do not sit and talk and be loud in the sleeping area. Rows are marked, please cram in your tents tightly to the next tent to make sure we have room for everyone. It's a tight fit but it works :).

Our pop up tent area is located right up by the race action. Each solo team and teams of 3 are allowed a 10x10 space for a pop up tent. Teams of 4+ are allowed a 10x15 pop up space. Rows are marked, please pop up your tent right next to one another to allow for room for everyone to have their tent. Tent walls are Ok, no generators, no fires of any kind please - propane camp stoves are Ok.

In order for you to get to the race site, you will need to take a 30min ferry ride from the tip of Door County, to Detriot Harbor on Washington Island. If you've never riden the Ferry before, please read the details below to learn how it works and be prepared.

Washington Island Ferry
1. Please allow for an extra hour to. wait in line at the ferry. We've found there to be longer lines during the summer season as the Island can be a popular place for visitors. Expect to wait in line!

2. Once you are near the front of the line, you may exit your car and walk to the small ticket building right at the front of the docks. Pay for your ticket with cash or card. You can find pries here. Make sure you keep BOTH TICKETS as one of them is your ride to the island, and the other your ride off the island.

3. Once its your turn to drive onto the ferry, you will be directed by the crew on where to park. They squeeze cars in tight, so if you feel uncofmrtable parking on the boat, the crew will park youor vehicle for you. Once you're parked, turn on your parking break and turn off your vehicle. You may stay inside your car, or head up to the deck on the top of the ferry and enjoy the ride. It can be wavy, sometimes really wavy - all part of the experience ;)
4. Upon arriving, remove your parking break and exit the ferry. Follow the signs for Gislason Beach and you're adventure is underway!

2021 Athlete Guide



Hand Made Medals

As someone who races ultras myself, and understand the amount of time, money, and work that gets put in to complete an ultra event, It seemed silly to have some random person design your medal, only for it then to be made in China for a few bucks... So, we changed that.

In 2020, we began designing, cutting, painting and assembling all finisher medals by hand. We spend hours gluing the tiny pieces together and coming up with the coolest design we can. I'll be honest, it's a bit more work than we thought it was going to be, but in the end, when all the medals are together and we get to hand you a bad ass, hand made finishers medal that actually means something, it's so worth it.

You put in the hours training, you should be rewarded with something unique made by people behind the event.
