Dear Butter Cream Gang,
I have you in mind. I just want to share some science/research/experience-based perspective on pre-race/run nutrition and then leave you to your own devices to ultimately decide what is best for you. I’ll also sprinkle in some facts about the run, your goals and how that affects your training. In other words this note will be all over the map and disorganized – that’s me :).
Let’s start w/ WHY/WHAT. Why are your running the marathon/half-marathon? What is your purpose? If it’s to beat your best time then you’ve done it before and your training is going to be performance-based. IF, it’s your 1st, and you’re using the run as an opportunity to make a lifestyle change, lose some weight and accomplish as goal…THEN your training is a completely different animal and therefore much of what you do should be a tad different than a “racer.” This pertains to some of the training and all of the nutritional approach. Someone wanting to lose weight will essentially do completely opposite of what an endurance athlete is doing. Two different goals = two different approaches (that happen to be opposite ea other). The reason largely resides in storing vs. mobilizing energy (calories) and how the body utilizes energy while performing.
FYI – most (99%) of the newbies that want to lose weight and take on a running event are doing it wrong. They’re taking all the advice from trained runners and are applying it to themselves (non-trained runners). They actually inhibit their efforts to lose weight and many give up the effort b/c of this fact and the perception that for all their effort there’s little return. NOPE…you’re just doing it wrong. It’s really easy to change too
Remember this…insulin is a storage hormone (stimulated by food intake) and epinephrine (EPI) is a mobilizer that’s stimulated by action (fight or flight).
A trained runner wants to store as much energy as possible to perform well during the run. Someone wanting to lose weight wants to mobilize (burn) as much energy as possible to lose weight. It’s a balance.
Newbies have their work cut out but it’s different. Those wanting to lose weight need to dump the bat belt (that tool belt w/ 1000000 calories of GU and maybe a taco tucked in there somewhere) and let their bodies burn fuel (not add more!). You can wear the bat belt on race day after you’ve dumped 10-30 lbs. or whatever amt. of weight. You ingest carbs while running for energy when you have literally tens of 1000s of calories of energy in the form of FAT available. That’s insane and totally counter-productive but not your fault…you were simply mis-informed.
TO BE CONT…. I have to go run 😉
