Spartan Super run

Preparing to run the spartan super in august. I ran this a few years ago at a different location and found out that I wasn't in good shape at all. Unfortunately (because of fitness levels dropping g, not because of my boy!) since then my wife and I are not in any sort of shape at all. We haven't found a workout plan that incorporates a 9 month old boy. I'm pretty concerned at this point because there's only 2 months before the race! I

I'm hoping other people here have been in a similar situation and are willing to share their workout regimen with me!

Here is some information on the race itself if you're unfamiliar with it.
