Swim for Grand Traverse Bay

We'll be in Suttons Bay this year! Our official start line and two-mile course for 2025 will be announced shortly.

Swimmers and support paddlers can pick up their Swim packets on Friday, August 8, 2025 from 4-6pm (location to be announced). Alternatively, packets can be picked up the day of the event (Saturday, August 9, 2025) beginning at 7am at the start line.

If you pick up your packet on Friday, you will still need to check in Saturday morning to get your number!

The Swim starts at 8am, with check-in beginning at 7am and a mandatory safety briefing at 7:45am. All swimmers and support paddlers must check in at the start line even if you already picked up your event packet. Event organizers will write your swimmer number on the back of your hand and your shoulder, if visible.

Depending on the number of swimmers, there may be more than one start group, including one for unescorted, experienced open water swimmers and another for those with support paddlers.

Event Cut-Off: 10:00am/2 Hours from start
Swimmers that have not completed the course within 2 hours of the start will be escorted out of the water.

We work with the U.S. Coast Guard; Michigan Department of Natural Resources; and Leelanau County Emergency Management, Marine Patrol, Law Enforcement, and Fire/EMS to ensure safety from start to finish. Motorized safety boats will monitor the entire course, and lifeguards and medical personnel will be on site.

Our experienced Safety Squad will ensure swimmer safety along the course. They act as spotters for designated swimmers and support swimmers along the course in obtaining evacuation or medical assistance from a rescue boat. Swimmers are also encouraged to have a support kayaker accompany them, traveling just out of paddle's length to remain close enough to immediately assist in the event of an emergency.

A mandatory safety meeting will take place at 7:45am for all participants, including swimmers, paddlers, and support personnel. Swimmers must wear the numbered swim cap provided, have their race number on their hand, and follow all announced safety rules without exception.

Wet suits or technical suits are allowed, as well as other swimming gear such as snorkels, fins, and kickboards. Swimmers using a wet suit or other swimming gear must inform the event organizers when you check in the day of the event. Swimmers wearing wet suits are still eligible for swim prizes, but those using additional gear do not qualify for timed prizes (fundraising prizes still apply).

All swimmers are required to fundraise or donate a minimum of $150 to their fundraiser by August 8, 2025. If you are under this amount your credit card on file will be charged on the morning of August 9th for the difference. For example if you raise $120, your card will be charged $30.

While the required fundraising minimum is due August 8th, your fundraiser will stay open until August 10th if you'd like to continue fundraising over the required minimum.

August temperatures in northern Michigan average a high in the mid to upper 70s, with lows in the high 50s to low 60s. Expect water temperatures to be in the upper 60s to low 70s depending on how warm of a summer we have had.

Every effort will be made to hold the Swim on the date and time it is scheduled. We will swim ran or shine. In the event of inclement weather such as lightning or a serious storm, the event may be postponed up to 2 hours in hopes the weather will pass. However, if the bad weather does not pass and swimmer safety comes into question, the event will be cancelled. If that is the case, there will be no refunds, credits, or transfers with no exceptions. You agree to this weather policy when you register for the event.

Parking details will be available soon.

Although the Swim is not a sanctioned event, timing services are provided. Awards will be given in wetsuit and non-wetsuit categories to the top male and female swimmers in various age groups. Swimmers can also access their results after the event.
