NOVELTY - The device (10) has a processor (60) coupled with a visual display e.g. LCD, a satellite navigation receiver i.e. global positioning system (GPS) receiver, and a memory element (64). The processor identifies a triathlon event e.g. bicycling event, in which a user is currently engaged based on current speed of the device and interval information. The processor calculates performance information specific to the identified triathlon event based on the current speed and/or geographic location. The processor presents a visual indication of the calculated performance information on the display.    USE - Portable fitness training device for providing triathlon performance information during an event swimming event, bicycling event and a running event, for a runner or bicyclist. Uses include but are not limited to total distance, total distance goal, speed and speed goal.    ADVANTAGE - The device uses information from a global positioning system component, an input portion of a user interface and an input portion of a data interface to assist the user in accomplishing a set of tasks including reaching a performance goal, navigating, and accumulating statistics. The device automatically tracks user performance, thus eliminating a need for the user to manually measure performance during a training session or follow a pre-determined course. The device communicates goal and performance information to the user, helps the user to reach pre-defined goals during the training session by informing the user of progress toward the goals. The device automatically accumulates and stores performance statistics, and eliminates a need for the user to manually record performance information and maintain the information for extended periods of time. The device communicates global positioning system-based navigation information to the user, and enables the user to visually monitor his/her location on a map or position on a course.
