Paul, is this data only from when you're running - no warm up/cool down? e.g. you hit "start" when you start to run and "stop" when you stop running - no warm up and cool down included in the data?
It's the whole thing! It includes a "warm up" though for most of the type of running I do, I don't really do a separate warm up. I don't really do much of a cool down either :)
