Claim 15:
16. A system configured to determine a 6 minute walking distance of a user, the system comprising:
a portable electronic device, comprising:
a first housing;
a set of first motion information sensors that generate first motion data in response to movement of the first housing; and
first communications circuitry; and

a wearable electronic device, comprising:
a second housing;
a second set of motion information sensors that generate second motion data in response to movement of the second housing;
a set of activity information sensors that generate heart rate data in response to a heart rate of the user;
second communications circuitry that is configured to receive the first motion data from the first communications circuitry; and
control circuitry, configured to:
calibrate the second set of motion information sensors based on the first motion data, and
estimate the 6 minute walking distance based on the first motion data, the second motion data, and the heart rate data.
