Newbie in need of friends!

I've used MFP on and off for the past year but am just now really getting serious! I am training for my first marathon relay (my leg equals 10K) and need to get my diet in check! I am a working mom to a one-year old boy and am finding it really hard to fit healthy cooking and workouts into my daily schedule! Could use some motivation and support (and will do the same for others!)!!
