Performance monitoring systems and methods

1. A portable electronic system for creating an electronic training journal using a portable electronic device, comprising:

a display screen:

a user input;

a satellite positioning system receiver;

an accelerometer;

a wireless communication transceiver;

a memory; and

one or more processors configured to:

receive first electronic fitness data corresponding to a first fitness activity;

store the first electronic fitness data in the memory;

receive an indication that the user is engaging in a second fitness activity;

determine that the second fitness activity corresponds to the first fitness activity based on the indication; and

display a recommendation for the second fitness activity based on the first electronic fitness and data after determining that the second fitness activity corresponds to the first fitness activity.

2. A method of creating an electronic training journal using a portable electronic device, the method comprising:

creating a first electronic training journal entry by collecting electronic user data related to a first health-related action via the portable electronic device, the portable electronic device comprising a microprocessor, a display screen, a user input, a satellite positioning system receiver, an accelerometer, and a wireless communication transceiver;

storing the electronic user data on a computer readable medium;

linking the first electronic training journal entry to a suitable database entry;

processing the electronic user data with a microprocessor;

providing a second health-related action recommendation to the user based on the processed electronic user data; and

creating a second electronic training journal entry based on the second health-related action recommendation.

3. The method of claim 2 , wherein the first electronic training journal entry includes foods eaten, and

wherein the suitable database is a nutritional database.

4. The method of claim 2 , wherein the first electronic training journal entry includes a performed exercise, and

wherein the suitable database is an exercise database.

5. The method of claim 2 , further comprising:

correlating the electronic user data related to the first health-related action with electronic user data related to the second health-related action.

6. The method of claim 5 , wherein the electronic user data related to the second health-related action is input by the user.

7. The method of claim 5 , wherein the electronic user data related to the second health-related action is data previously stored in the computer readable medium.

8. The method of claim 7 , wherein the electronic user data is related to a physical activity.

9. The method of claim 2 , further comprising:

providing a prompt to the user related to the second health-related action.

10. The method of claim 9 , wherein the prompt is a visual prompt displayed on the display screen.

11. The method of claim 9 , wherein the prompt is an audio prompt.

12. A method of creating an electronic training journal, the method comprising:

providing an electronic data entry region on a display screen of a portable electronic device, the portable electronic device comprising a microprocessor, a user input, a satellite positioning system receiver, an accelerometer, and a wireless communication transceiver;

collecting electronic user health data in the entry region;

storing the electronic user health data in a computer readable medium;

collecting first electronic activity data related to a first training activity;

storing the first electronic activity data;

receiving an input on the display screen related to a second training activity;

displaying a recommendation related to the second training activity based on the first electronic activity data.

13. The method of claim 12 , further comprising:

displaying the first electronic activity data on the display screen,

wherein displaying recommendation includes displaying the recommendation on the display screen.

14. The method of claim 12 , wherein the first electronic activity data is stored in the computer readable medium.

15. The method of claim 14 , further comprising:

collecting an annotation related to the first electronic activity data; and

storing the annotation in the computer readable medium.

16. The method of claim 15 , further comprising:

displaying the annotation on the display screen.

17. The method of claim 12 , further comprising:

providing a menu region on the display screen to control an electronic function.

18. The method of claim 12 , further comprising:

displaying the first electronic activity data on a second display screen,

wherein displaying the recommendation includes displaying the recommendation on the second display screen.

19. The method of claim 18 , wherein the first electronic activity data is stored in a remote computer readable medium.

20. The method of claim 19 , further comprising:

collecting an annotation related to the first electronic activity data;

storing the annotation in the remote computer readable medium; and

displaying the annotation on the second display screen.
