GPS feature to track cardio and other exercises

The addition of integrated gps would be very useful for distance based workouts. Even the abitlity to have distance based workouts and enter distances manually.

The GPS feature would be for any exercises that could or should be measured by distance. For instance if you go for a run outside, instead of measuring the exercise in seconds (time), you could measure the exercise by distance. The future would require that you start the exercise and the GPS would run in the background, measuring the distance until you stop the exercise. Progress for such exercises would be measured in distance instead of time or reps. An alternative to that for this program would be to be able to use a third party GPS to determine distance and then enter it into this app manually. It just does not make much sense to measure a run or a walk or any other similar traveling exercise in seconds or reps.

I hope that clarifies my suggestion a little bit.
