10K InvitationalCongratulations! You have been accepted to register for this elite event. PLEASE RECRUIT A PADDLER. A kayaker is preferred. That paddler will join our safety team, and will provide you feedings and water as needed.

Registration for this event closes at midnight on Tuesday, July 25th, or when all spaces are filled. Register early to secure your place.

Once you register, please train in earnest. Many marathon swimmers find the 10k Dart Training Plan useful. (If you have a training plan you’d like to share, please let us know.)

We will check in with you to ask how your training is progressing at least once before the swim.Approximately one week before the event, we’ll send you your Welcome Letter with all essential details.

“The safety aspect was very impressive. I don’t remember more safety awareness at any event. That is so reassuring and worth paying for.”
— Melinda B, 2016
