The Inaugural Washington DC Sharkfest Swim benefiting Special Olympics International will be hosted at the National Harbor. This amazing venue is the perfect spot for your first open water swim, or your hundredth. The course is just right for first time and novice open water swimmers as the National Harbor provides a very calm and protected swim area. There will be three distances: 1Km, 2Km and 4Km. All three distances will start and finish off the Pier at the National Harbor. We will be staggering the starts so that you can swim BOTH the 4Km & 1Km, or BOTH the 2Km & 1Km. Athlete check-in, race day registration and awards ceremony will take place at National Harbor Plaza. National Harbor is a unique waterfront wonderland with the Capital Wheel and The Awakening (art sculpture) and will be a fun spot to bring the whole family to enjoy time together after the swim.

PLEASE NOTE: This is a great swim for novices and first timers. We do recommend that 4K swimmers be able to swim one mile comfortably in a pool in under 40 minutes.
