Seattle’s Annual 10K Invitational Open Water Swim
Welcome to the world of marathon swimming!
This challenging endurance event in Lake Washington is for experienced distance swimmers only. Come celebrate its third year! We purposefully limit registration in Seattle’s 10k Invitational to twenty-five qualified participants. Last year, many swimmers described it as one of the best open water experiences they’d ever had.
All swimmers will receive a branded swim cap and their choice of champagne or chocolates; all support personnel receive a gourmet sandwich from an award-winning bakery. Swimmers must provide their own paddlers to supplement our trained safety craft, which includes kayakers, stand-up paddlers, and at least one Zodiac.
Like all our events, Seattle’s 10k Invitational is non-competitive. Swimmers challenge only themselves. The result is a truly fulfilling and holistic outdoor adventure, with camaraderie and swag that can’t be beat. We hope you join us this year!
How to Register
We accept participants based on their RECENT open water swim experience. Preference is given to those who have swum further than 5k at least twice in the last two years.
