This goal has the following fine print specified by dehowell:

Activity must be 10 contiguous minutes or longer to count. Goal will be set to max aggday to enforce spreading activities through the week -- don't try to bank all activity for the week in one day.

Walking and other low-intensity cardio counts 1:1, running and other high-intensity cardio counts 2:1, as described in this Lifehacker article on fitness guidelines:

If there is a mix of low intensity and high intensity, then count 2x the time in HR zones 2 and above.
