Across the weekend
making cupcakes on an empty stomach
going to the most productive (yet still enjoyable) practice you've attended in years
having a small breakfast and not bringing a post-practice snack, so that by the time you've arrived home to work on school stuff, despite the fact its Saturday afternoon (sigh), you are literally nauseous from hunger.
doing your long run in the evening so you can be productive (eg. read for class x2, draft a paper, and attend a comps meeting, and go grocery shopping and make dinner for mon/tues) during the day
eating a cupcake and cookie during the meeting which is conveniently scheduled over dinnertime, then running 10 miles on a 1 pm lunch and said dessert items. (lack of nutrients + high fat content = unhappy tummy)
