is created by Doug Thomason, a USMS competitive swimmer living in Nashville, TN. Doug’s inspiration for came during a working trip to St. Petersburg, Florida. During his trip, Doug practiced a few days with the local SPM masters club coached by Fred Lewis. These practices were prescribed by Coach Lewis using a Colorado Systems clock with workout intervals pre-programmed and with printed paper listing the workout details provided for each lane. After several years of thinking through this, Doug has ported the concept to a database driven content management web site that he hopes that you and others will find useful. Today, Doug uses on his iPhone™ inside of a LifeProof™ case at the pool side.
