Good luck Ali. Keep us updated (if you feel so inclined).
This website is good for keeping a diary of your workouts. Last time I was "training" for something, writing it down helped me keep as motivated as I get with this sort of thing. They also have suggestions for programs-e.g. how far to run how many days a week and when to build up kms etc... to reach a goal + specific programs for things like weight loss.
