RunGap works very nicely for exporting data to other services. Like others have said, the good stuff costs $2 every 3 months.
Alternatively, there's an app called HealthFit (which I've not used), but does pretty much the same exporting options. It's a one time app purchase of $5 (or so).
Personally, I like RunGap because of one particular feature that I've not seen any other app incorporate.
When you view a particular workout (in my case, a run), you can compare that run with other runs that are "similar". So if you run the same route a lot, you can easily select all of your other runs and it does a quick filter. It's based on the GPS map, so if you run laps, they'll all be considered "similar" even if they aren't the same distance.
