For 2023 we are bringing a new and exciting addition to the fitness events on the Island. Alameda is known for its beautiful running trails and beaches, so we decided to add a Swim/Run to our list of events this year. 

The race weekend consists of two events, a 5k stand up paddle and a new Swim and Run Aquathlon event where swimmers will swim out from the shoreline Kite Shack, around the buoys and back in, where they will transition into their running shoes and follow the 5k course out and back along the beautiful Shoreline trail. 

This Aquathlon will max out at 300 participants for the first year. Don't wait to the last minute to register

the stand up paddle will start at 9:30am and will take you a bit further out from the shoreline past Ballena Bay and back. The 3.1 mile 5k paddle will be a big triangular loop in the Alameda Bay, with a shorter 1 mile option. for more information and to register for the paddle visit:

The Aquathlon will have a beach start swim with groups no larger than 50 athletes. Actual wave breakdown will be determined closer to the event. Tentative start time is 8:30am, but is reliant on the tide schedule and we will monitor as we get close to race day. The 750 yard swim will be a triangular out and back, keeping the buoys on the swimmers right with approximately 100 years out, a 400yard cross (turn) and then another 250 back along the shore to the finish and the return will go with the tide, so a smooth swim back. There will be a transition area to change from swim to run gear, and the event will finish with a 5k run along shoreline drive
