'Jogging' can be defined as being able to run and keep a conversation going without being out of breath. 'Running' is when the effort is a bit harder. This all dependent on your heart rate. This a good guide:

Personally, I don't like the phrase 'jogging' - as far as I'm concerned if you're not walking you're running, regardless of how fast (or slow) you're going!
I would also recommend a core strength session once a week, such as Pilates, and possibly add a body circuit and/or weights into the mix. You might want to try yoga, but I prefer the straightforward approach of Pilates. People tend to forget that the arms and core are just as important as the legs for running!
I feel the same way! If I am not walking, I must be running. The effort sure does feel like running to me!
