Why Casco BAy?
The Casco Bay Islands lie off the coast of Portland, Maine, and consist of several hundreds of islands. Some of these are uninhabited and relatively small, while others are larger with established communities, each featuring its unique charm and vibe. The most popular islands to visit include Bailey, Chebeague, Cliff, Great Diamond, Little Diamond, Long, and Peaks.

These islands are home to small towns and villages that have been around for generations. They are perfect for leisurely walks, bike rides, relaxed meals, and a peaceful atmosphere, starkly contrasting the hustle and bustle of urban New England on the mainland.

Getting to Casco BAy
If you’re traveling to Casco Bay, the nearest airport is Portland (PWM). Portland is the closest mainland coastal city to the islands. Once you’re in Portland, you can easily access many islands via the Casco Bay Lines Ferries or private water taxis in the area. On race day, all athletes and volunteers will be transported to their respective start lines using the ferries of Casco Bay Lines. Tickets are included for every athlete and volunteer. However, spectators will not be provided with complimentary tickets and must plan their transportation around the islands. After the event concludes, the ferry back to the mainland is free for everyone and works on a first-come, first-serve basis.

Around Casco BAy
There are plenty of things to do in Greater Portland and Casco Bay. You can explore museums, theaters, go hiking, boating, or visit fairs and festivals. Take a walk or bike ride on the Eastern Promenade, or go on a cruise to the islands of Casco Bay. You can try ferries, historic schooners, or sunset lighthouse cruises. If you’re interested, there are also amusement and water parks, as well as live racing events. You can immerse yourself in arts and culture at the Portland Museum of Art, Wadsworth-Longfellow House, or Maine Narrow Gauge Railroad Museum. And don’t miss the opportunity to dine at Dimillo’s On the Water or the Top of the East Lounge, or attend special events like Harvest on the Harbor.

PACKET PICKUP RULES

Therefore, we allow one team member to pick up an entire team packet, as well as family members and friends to pick up packets for racers, as long as they have the registrant’s permission and a valid ID.
- To make the check-in process quick and easy, please show your QR code at the packet pickup. We will email this to each racer the week of the event. Each QR code is specific to your registration. If you do not have your QR code, you can check in with a photo ID. You do not need to show a USA Triathlon Membership card, even though this is a USAT sanctioned event.
Can’t Pickup Your Packet the Day Before?
If you are unable to pick up your packet the day before the race, you have one more option. You can choose to pick it up on race morning by selecting “Race Morning Packet Pickup” during registration or by adding it to your RunSignup account later. This option is available on a first-come, first-served basis. Those who choose and pay for this option will have a pre-stuffed bag with their name on it ready for them before the race. Depending on the event, this pickup may be available before boarding a ferry to the start, or it may be at the common start/finish area. The add-on is per person, so each person on a team must select this add-on during or after they registration.

A husband, a father, a sportsman, an event organizer and a leader, Jeff Cole cared deeply about each and every person he had contact with. He grew up on the water and worked as a lifeguard and was a volunteer fireman at the Kennebunk Fire Dept for over 20 years, founded and produced multisport races – from the Fireman’s Tri in Kennebunkport to White Mountains Tri in Franconia, New Hampshire. He served on the Board of Directors for numerous businesses, schools, and sporting organizations and yet spent a few weeks each year living off the grid completely self-sufficient. Jeff was an independent thinker but also a consensus builder. He never asked anyone to do something he was not prepared to do himself. He is fiercely missed but his legacy lives on through his wife Kim, daughter Rachel, son Ben, his friends and through the SwimRun USA events he pioneered.

All racers are required to wear a wetsuit during the swim. We suggest using a Swimrun wetsuit rather than a full-body triathlon style wetsuit because Swimrun wetsuits are lighter, more flexible, and easier to run in without overheating. However, any type of wetsuit is acceptable.
For those who do not own a wetsuit and prefer not to purchase one, we have a limited number of Ark Sports rental wetsuits available. These suits can be rented as an add-on during registration, or you can add them later by logging into your RunSignup account and editing your registration to include the rental suit.
ALREADY REGISTERED AND NEED TO ADD-ON A RENTAL WETSUIT? – CLICK HERE
If you have rented a wetsuit, you can pick it up during packet pickup. We may not have extra suits available for rent if you have not reserved one in advance, so please plan accordingly. If you rented a wetsuit and have opted for race morning packet pickup, your wetsuit will be available at that time.
After the race, please remember to remove any items from the wetsuit pockets and return it to the wetsuit tub at the finish line.

Join us for a unique way to experience the race! We are offering Spectator Boat tickets on the Cat (Fogg’s Boat) so you can cheer on your friends and family competing in the race. The boat trip includes a tour of some of the islands used by the world series course and most of the islands used by sprint/experience courses, with opportunities to watch the swim and experience merge points of all distances. You may have the chance to get off the boat as well along the way to cheer on participants from shore. Your spectator boat ticket includes a shirt and a meal/drink wristband for the post race party at the Lion’s Club on Peaks Island, where you will be dropped off. Please note that you will need to arrange your own transportation back to the mainland via the public ferry nearby.

Volunteers are the backbone of the race. We could not do what we do for the athletes, without volunteers. We are always in need of volunteers that are ready and willing to help with various positions during race weekend. All registered volunteers receive a t-shirt, and meal after their shift concludes. All volunteers must register via our system and check in and out for their shift. Some volunteer positions even have stipends associated with them and groups that volunteer and identify themselves as such will be eligible for a donation.

Every water stop will be equipped with a minimum of two coolers.
- One cooler will contain regular water.
- The other cooler will be filled with Precision Hydration electrolyte-infused water. You can identify this cooler by the “PH” marking on its top.

Please ensure that any trash you have is disposed of in the designated trash bag, typically tied to the handle of one of the water coolers. Leaving trash on the course or failing to use the trash bags will result in immediate disqualification and a ban from all future races.
