Seattle’s Annual 10K Invitational Open Water Swim

Registration for this event is closed: all spaces are filled.

This challenging endurance event in Lake Washington is for experienced distance swimmers only. Eighteen swimmers completed the course in 2017, and many described it as the best swimming experience they’d had all year.

We supply trained safety kayakers and also encourage swimmers to recruit their own paddlers. Swimmers are provided with drinking water along the route and a feeding opportunity at the 5k mark; your own paddler can provide feeding opportunities whenever requested.

“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
