Race Information
23rd Annual Fat Salmon Open Water Swim (3.2 miles)
Event hosted by: Orca Swim Team
SANCTIONED BY PNA for USMS Inc. # 363-W002

This swim had to be cancelled due to high bacteria count in one water sample taken at Madison Park Beach on July 10th.  We are meeting at Madison Park Beach at 9am-10:30am on July 15th to give out participant t-shirts, caps, and purchased hoodies.

WHEN: Saturday, July 15, 2023

WHERE: MADISON PARK BEACH on Lake Washington  (1900 43rd Ave E, Seattle WA) - Pre-race check-in and finish line of the swim

COURSE: Point-to-point course will follow the western shore of the lake from I-90 in a straight line marked with buoys.  In water start immediately offshore from Day Street Boat Ramp, finish across timing mats on shore at Madison Park Beach; participants will need to ascend 4 stairs at the completion of this race.  Water temperatures are typically 67-73 degrees fahrenheit during the summer but can vary significantly; be prepared for a cold swim.  See RACE MAP.

  • 6:00 - 7:00 AM: MANDATORY Check-in
  • 7:05 AM: Pre-Race Meeting - MANDATORY for all swimmers
  • 7:20 AM: Carpool to 3.2-mile start at Day Street Boat Ramp (1402 Lakeside Ave S, Seattle, WA)
  • 8:15 AM: Start 1st wave from Day Street Boat Ramp, swimmers will be sent off in 5 separate waves scheduled every 3 minutes.

SAFETY: Large buoys (approx. every 1/2 mile) will mark the course. Motor boats, kayaks and lifeguards will be located along the perimeter of the course. Swimmers must wear the swim caps provided at check-in. A MANDATORY safety meeting will be held before the event start. Friends and family who are not registered for this event cannot swim along with you. 

RULES: Current USMS rules will govern this event. Wetsuits and full-body swimsuits are allowed in the wetsuit division.  In the unlikely event that the water temperature exceeds 78 degrees fahrenheit, wetsuits will not be allowed.   No additional devices to help speed, pace, buoyancy, or endurance are allowed (such as MP3 players, pull buoys, webbed gloves, fins, snorkels, etc.).  Any questions, refer to USMS guidelines.  Due to the large number of swimmers, personal float buoys for identification and safety are not permitted without special advance permission of race director.   Those who use a personal float buoy will be classified in the "wet suit" division per USMS rules.

MORE ABOUT SAFETY & PULLING SWIMMERS: We must maintain a certain swimmer-to-boat ratio to keep our permit AND, more importantly, to keep everyone safe. Swimmers will have 2 hours to complete this event; Swimmers who fall too far behind the back or are not on pace to complete the swim within 2 hours will be pulled from the course at 1.5 mile and 2.5 mile markers.


  • Sorry, there are not any refunds or exchange of entries for any reason. 
  • Do not register for this event if your estimated time to complete this 3.2 mile open water swim is more than 2 hours. When you register you will be asked to provide an estimated time to complete this open water swim so we may assign you to the proper wave group.
  • NO filling of no-show slots - Someone else cannot swim for you - this jeopardizes our insurance and our ability to offer this event in the future.
  • There will be NO SWIMMING if you have not checked in ON TIME and attended the pre-race safety meeting.
  • Swimmers are required to check in as they enter the water at race start and check out as they exit the water at the race finish.

TRANSPORTATION / PARKING / CARPOOLING:  There is limited parking in the area of the event so carpooling is encouraged as much as possible.  We are guests of the neighborhoods for this event so please observe and respect parking regulations.  Swimmers are responsible for their own transportation from the check-in location at Madison Park Beach to the race start at Day Street Boat Launch (3 miles).  We will encourage the formation of carpools at the conclusion of the pre-race safety meeting.  Offer a ride to a fellow swimmers and fill up your car if driving to the starting point.  If you got a ride to the starting point, please offer a ride back to the starting point after the race to your driver.

WETSUIT and NON-WETSUIT DIVISION CHANGES:  If you are already registered and want to change from non-wetsuit to wetsuit division (or vice-versa), it is easiest for you and for us if you submit this change via email registration@fatsalmonswim.com   by end of day July 9th.  If you are not sure by July 9th, you can do so the morning of the event by requesting this change at the "change" table.  The US Masters Swimming Rule Book section for Open Water Events is strict about what qualifies as "non-wetsuit". Article 303.4 says Category I Swimwear (non-wetsuit) can only include "a swimsuit, cap or caps [including neoprene], and goggles". If it doesn't fit Category I then it is Category II - wetsuit.
