Our 20th anniversary Grimaldo’s Mile will be on July 20, 2024.

This is the quintessential NYC open water 1 mile swim.

This swim honors the lifeguard Grimaldo Medrano who made it possible for NYC open water swimmers to swim past the jetties without being whistled in by the lifeguards. Grimaldo’s loyal confidence and acceptance of us open water swimmers made it possible for us all to swim today in what we think is the perfect training grounds. Unfortunately cancer took him from us when he was only 34. This swim honors and recognizes his life and commitment to our community. We thank him for all he did for us.

This is the perfect “newbie” race, for the beginner racer or triathlete. Conditions are usually gentle due to the geographically protected waters of Brighton Beach and Coney Island. You swim parallel to shore so if you have any doubts you can easily swim to shore, find a volunteer or race official, and hand in you race chip and say, “today just wasn’t my day, maybe next time.”

Practice your beach starts and your sighting before the race, but after the race invite your friends to join you in taking advantage of Amusements, Games, and Dining that Coney Island and Brighton Beach can offer you.

Grimaldo’s Mile is organized entirely by volunteers. Can you help support CIBBOWS on race day? Whether it's kayaking, helping with set up, walking the beach and keeping eyes on swimmers, packing up supplies for storage, or cheering swimmers along the way, please come join us! Sign-up coming soon.


Registration will be in the boardwalk pavilion opposite of New York Aquarium’s Education Hall. Please refer to the Venue section at the bottom of this page for more details and a photo of what to look for.

Timeline (subject to change)

6:00 am  – Swimmer check-in opens. Meet at the pavilion on the boardwalk outside of Education Hall.
6:45 am – Check-in closes. Any swimmer not registered by 6:45 will not be allowed to participate. This is a hard limit. Please give yourself plenty of travel time and arrive well in advance.
6:45 am – Mandatory swimmer safety briefing. Any swimmer who does not attend the swimmer safety briefing will not be allowed to participate.
7:00 am – Swimmers walk as a group to race start at Grimaldo’s Chair, about 0.75 miles down the beach
7:30 am – Race starts! We will continuously launch small waves of swimmers, roughly seeded from fastest to slowest.
9:15 am – Course closes. Any remaining swimmers will be asked to exit the water.
9:15 am – Awards Ceremony and Honoring Grimaldo’s Family.

Race Timing

Swimmers will be given timing chips to velcro to their ankles. A $30 fee will be charged for unreturned chips. Timing starts upon crossing the starting mat before entering the water, and stops upon crossing the finishing mat after exiting the water. You are competing for your own personal time — the swimmer next to you may have started at a different time, so please focus on your own personal effort. Any swimmer aggressively swimming on top of another competitor is subject to disqualification.


Parking will be limited, because we are unable to use the lot behind Education Hall.

Feel free to use street parking, or park at the lot on Stillwell Avenue by the boardwalk. We recommend using the subway, but please allow extra travel time as there will be limited train service at this early hour on the weekend.


The Parks and Recreation Department will open public restrooms on the Boardwalk as early as 7am, but we cannot guarantee a prompt opening. There are restrooms in Education Hall as well. Please do not use these restrooms for changing, as they are small and people need to be able to access the stalls.

Swim Angels

If this is the first time you are racing, or if you’re getting butterflies and just want some extra support, we will have trained “swim angels” swimming among you during the race and watching over you. CIBBOWS swim angels are experienced open water swimmers who know CPR and first aid, and promise not to leave your side in the ocean!

Securing Your Gear

Limited bag check will be available. If you have more than one medium-sized swim bag, please make arrangements for a friend or family member to watch your stuff. CIBBOWS is not responsible for items left on the beach.

Food and Water

CIBBOWS will be providing food and water after the race. Please bring any extra pre-race fuel you need to the race.

Special Accommodation

CIBBOWS is happy to provide reasonable accommodation to any participants requiring special assistance. Please reach out to with your request before registration and we will be in touch.

Entries are non-refundable and non-transferable. Every effort will be made to conduct the race; if the race is cancelled due to inclement weather, there will be no refunds
