The Whidbey Adventure Swim will hit the waters off Langley on Sept. 8 this year.

For $40, swimmers can brave the chilly waters of Saratoga Passage for a chance to win the second-annual open water race. The course is split between a 1.2-mile and 2.4-mile category, with the latter doing a second lap of the triangle course before swimming back to the shore at Seawall Park in Langley. Day-of and late registration after Sept. 3 will cost $50.
