Scheduling time for exercise

My life is about to get a whole lot busier, at least for the next 9 weeks.  I've taken on a part time freelance gig that I honestly couldn't be more excited about...I'm over the moon with anticipation and glee and the thought of getting some precious office time and meaningful conversation with other adults, not to mention a chance to utilize my skills and talents outside of the child rearing realm.  Call me crazy, but I am SUPER excited at the prospect of going to work.

That being said, I just spent the last hour trying to put together a workout schedule for the next 9 weeks.  I'm on the verge of hitting "print", knowing that the schedule will likely change a gazillion times, but I'm the kind of person where if I don't have something scheduled on the calendar, it's not going to happen.  And not running or working out is just not an option.

So, over the course of the next 8 weeks (I decided the last week in May would be a good, solid time to end my schedule, rather then venturing into June), I will be running 3 times a week: on Mondays, I will alternate between a tempo run and a "fun run", where I intersperse things like pushups, mountain climbers, planks, lunges, etc. along the way.  On Wednesdays I will be running trails (woo-hoo!) and Saturdays will be my long run days.  I am also going to attempt a Pilates workout at home on Wednesday evenings.  Tuesdays and Thursdays will be Zumba and strength training, alternating between upper/arms and lower/abs.  On Fridays I will work on my yoga home practice and do the 20/20 workout or another HIIT type workout, and on Sundays I will do Pilates.  Sounds ambitious while working 20 hours a week and taking care of a 3 year old full time, no?  Well, ambitious I am.  And somehow, I will make it work.  It's just that important to me.

I would love to get advice and thoughts from those of you who juggle employment/parenthood/exercise on what has and hasn't worked for you.  I know I will have to be flexible, but I also know that exercise is a top priority.  So, how have YOU made it work?
