Marathon Runner Sherrine Cancilla - Discovery Bay, CA 10/11/2006 My goal was a full marathon by the age of 40. I can boldly and confidently say that Oxia was (and still is) my training partner. Using Oxia enhanced my performance while cutting my recovery time throughout my entire training process. I also stationed family members at mile 7, 13, and 18 to make sure my Oxia was there for me from start to finish!! Thank you Oxia, you are now permanently a part of my life and my daily work-out routines.
