2015 USMS Speedo 5K & 10K ePostal National Championship July 5th and 26th, 2015

Spring is finally upon us! That means outdoor pools are opening soon and our beautiful Colorado Lakes and Reservoirs are preparing for Open water swimming! It is also time once again to challenge yourselves by participating in the 2015 USMS Speedo 5K and 10K ePostal National Championships, hosted this year by the Central Oregon Masters Aquatics. The object is to swim a 5K or 10K in a 50 meter pool between May 15th and September 15th, then submit your entries and splits online and see how you compare with the rest of the country! Whether you swim either or both for competition, fitness or for some form of "fun", you will feel ever so accomplished once you are done!

COMSA is sponsoring 2 opportunities to participate as a group at the beautiful outdoor 50 meter pool at Lowry this summer on Sunday, July 5th and Sunday, July 26th from 7 am to 10 am.
