The Vapor 300 is a running watch designed for core and competitive runners, who require a watch that can record splits, laps and intervals. These runners train four to six times a week, often run in locally organized groups and usually have a leader or a coach. They follow national and global runners for guidance and advice and are involved in competitions and events. The Vapor 300 tracks and stores data about their runs, helping them train more accurately and efficiently. It also has sufficient memory to store their data for future reference.
