Freestyle Differences Between the Pool and Open Water Open water swimming is increasing in popularity as more Masters swimmers jump into lakes, rivers, and oceans for an enjoyable swim. One of the most common questions I receive from these swimmers about open water swimming is, “Should I emulate how I swim freestyle in the pool in the open water?” ...

13 years ago Alex and Steve opened Transition Tri and hoped that it would be a place where athletes who like to swim bike or run could find the products they need and also meet people who share their passion. At this point we feel like we’ve accomplished that goal and so much much more. Now the time has come for us to pass the store to new ownership and let them run with it. We have just sold the store to Joshua and Stephani Shepherd who will write its next chapter. Our employees and customers are in good hands with them and we can’t wait to see where they take it. Sincere thanks to all of employees and customers who helped to make our dream a reality!


We’re saddened to share that our long time mechanic and friend Bill McCarrick has passed away. We have great memories of our time with him as a part of our team. His wit and story telling always lit up our store and his skill as a mechanic was a tremendous asset to our business but what we will miss the most is his friendship. Our staff sends condolences to his family and to all who cared about him. Rest in peace Bill.

There will be a Celebration of Life at 12:00 on January 6 at National Funeral Home on Lee Highway on Falls Church.
