We have disclosed devices and methods for monitoring an individual's performance during a physical activity. The devices may include multiple elements such as a mount adapted to releasably secure the device to the individual's wrist during the physical activity, a heart rate sensor coupled to the mount and adapted to obtain heart rate data during the physical activity, a satellite positioning system receiver coupled to the mount and adapted to obtain position data during the physical activity, an acceleration sensor coupled to the mount and adapted to obtain acceleration data during the physical activity, and an output coupled to the mount and adapted to output performance information to the individual during the physical activity. |
