Do you eat before you run?
Okay. I mean. Most say that you should fuel up before a run – ESPECIALLY before a race – but why? We all know that it helps to sustain your energy, keeps you going, helps to ensure sure you don’t crash mid-run… but I’m a morning runner – and I don’t always LIKE – or have TIME – to fuel up before I head out.
But what’s actually best?
Here are a few things to consider when figuring out what is best for YOU:
TIME:

How long do you need to digest your fuel?
And, according to Mayo Clinic – digestion time varies between individuals and between men and women. What does this mean for you? It means that IT DEPENDS. You may need to experiment and explore with different foods, times, and combinations before you find what’s best for you personally. What else does this mean? It means that when someone is telling you exactly what you should do – BE CAUTIOUS. Nobody knows what’s best for you except for…well… you.
Whatcha been eating all week?
Fueling up isn’t only about the pre-run snack or meal – it can also include everything you’ve been eating for days prior – and EVERYONE’S NEEDS ARE DIFFERENT. For me personally, if I eat too big of a meal the night before my race – I’M GOING DOWN. Seriously. I’ve had to move my “pre-run” meal to the entire week before the race. If I eat too late – say, carb-loading the night before the race – personally, my body definitely does not have time to process what I’ve eaten. When this happens, I get sick, have more cramps, and sometimes have a “heavy” feeling that keeps me from running as fast as I can. Finding what works best for you takes time though, and lots of trial-and-error. It’s taken me 6 years to figure out what’s best for me personally, and I’m still learning (and my body is always changing). So make sure you consider the fact that your body is using fuel that it has stored over time – not just from the morning of the run or race.
TYPE:

What type of run are you doing?
Long runs?
Lizzie Kasparek, R.D., sports dietitian for the Sanford Sports Science Institute – suggests “eating two to four hours before a long run.” Long runs require much more energy – which means you may not have adequate fuel in your system to keep you going without a little pre-run snack or meal. However – with this fuel – comes a digestion time. It’s important to consider how much you’ve eaten and how much time you’ll need to digest it before you head out for that longer run!
What about shorter runs?
According to Vishal Patel, chief sports nutritionist at Nuun, if you’re going out for a short run (say 3-4 miles) – you can likely “skip the pre-run meal or snack.” Why is this? Because your body may actually have enough energy stored up in the form of carbs and nutrients to get you through the run. HOWEVER – AGAIN – it is all about your personal preference and needs. If you find that fueling up before a short run best enhances your performance – GO FOR IT. Everyone has different nutritional needs, and you know those needs best.
FOOD:

What are you fueling up with & how much?
It’s also important to fuel up on the RIGHT KIND of foods if you’re going to be eating that pre-run snack or meal. And not just the right kind – but the RIGHT AMOUNT as well. We all know what high-fiber foods do… so maybe lay off the broccoli & beans before you go for your run. But fueling up on some carbs & protein – Kasparek suggests – can be quickly turned into energy to use on those runs. A little oatmeal, some toast and peanut butter, a power bar – just a few options to keep that energy high. But make sure you’re consuming an amount that optimizes your performance. Personally, I eat a power-bar a few hours before a race. It’s light enough that it doesn’t feel like a huge meal – but it gives me enough energy to get me through.
BOTTOM LINE:
It’s all about finding what’s best for you. And it will take a little bit of exploration and experimentation. Everyone has different needs, bodies, and schedules – and therefor, we all have different pre-run preparation. Finding what works best for you is an ever-evolving process, and that’s okay! Just keep exploring and enjoying the process! Share your pre-run fuel plan below!
