If you have ever trained for a race of almost any distance, chances are you have been told or have read about common race preparations — quit alcohol, carb load, train at the same time as the race — and have wondered, it is worth it? Myself and two other experienced runners are here to give you the truth…or at least the truth as we know it, about these common race prep practices.
Disclaimer: Everything I write on this subject depends on the individual. Every runner is different and different things work for different people. Experiment and see what works for you before you take anyone else’s advice, including mine.
Common Race Preparation Practice #1: Give Up Alcohol
Just typing that sentence seems ridiculous.
I hope it goes without saying you shouldn’t get drunk the night before a big race because you will be dehydrated, will not get a good night’s rest and will probably have head or stomach issues the next morning. However, if you indulge in one glass of wine or have a pint of craft beer, it probably won’t do harm and may even do some good.
This article in Runner’s World articulates why alcohol is not as harmful as once thought, and the below quote from sports nutritionist Nancy Clark, sums it up nicely:
“…as long as runners who are accustomed to drinking wine are drinking extra water and taking in other carbohydrates,” says Clark, “one glass of wine with dinner the night before a race doesn’t concern me.”
For me, having a glass of wine the night before a race sometimes relaxes me and allows me to fall asleep faster than I normally would, but I have to admit that I usually do not drink at all the night before a race.
That said, I drink every night leading up to the Las Vegas Rock and Roll half marathon and my slowest time yet is 1:39.

Not even buzzed.
Common Race Preparation Practice #2: Carb Load
I honestly don’t think anyone even does this anymore but I could be wrong. Sometimes that happens. I’m guessing even if some runners think they are “carb loading” they’re doing it wrong. Proper carbohydrate loading is a whole practice that starts days before the race, not the night before and is only effective for endurance events lasting over 90 minutes.
My best advice on this subject is not what to do, but what not to do. I think it’s much better to think about avoiding fiber than eating enough carbohydrates. You know why.
The only key meal is breakfast before the race. The meal you eat in the hours before the race should be something you practice in training. You want to get the right balance of carbs, fat and protein for the distance you’re running and for your metabolism.
Forget about carb loading and just think in terms of common sense. The key to fueling for a big race is practice. And definitely no new foods on race day.
Common Race Preparation Practice #3: Timing Your Training
This one always kind of baffled me and I don’t think I ever really tried to do it. I may have an advantage in that I’m a morning person and I don’t mind waking up at the crack of dawn and swimming, cycling and running my way to the afternoon. Ever since the boys started full days of school four years ago, I usually begin my training around 9am. I don’t know of any race ever that starts at 9am but I haven’t seemed to have had an issue.

Early morning swim start!
Somehow the Rock and Roll Las Vegas race keeps becoming a factor. This time it’s because that race starts around 5pm. I hate it. I hate waiting around all day for a race to start and having to eat at least two meals leading up to it. I was pretty worried about the start time the first year I ran it, and I even played with the idea of throwing in a run or two in training at 5pm, but I didn’t. Guess what? It didn’t matter.
Finding time to train is hard enough. I run a Ragnar in the dead of night after sleeping in a van for 2-3 hours, raced while battling a cold and did my first ever triathlon when the twins were three months old and my husband was out of town.
All of those races turned out fine. As long as your mind is there, your body knows what to do, regardless of time.

Whatever you do to prep for a race, remember the importance of your mental game and, if you’re not having fun there’s no point in doing it.

I really think the whole carb loading thing is for organizations to raise money for their pasta dinners the night before. lol. I’m the opposite with alcohol, I sleep horribly. Even if it’s one glass, it’s not as sound as without. That’s why I try to obstain before a race. But there’s sometimes I drink and it still turns out the same so who know? I think as long as you don’t go on a bender you’re fine.
Omg so true about the pasta thing. I seriously thought they debunked that like 10 years ago.
That’s awful about the sleeping and alcohol! But you’re right about sometimes things work and sometimes they don’t. Both of us know this whole running thing is a crapshoot, especially over 40!
100% agree on all these points. Yep, I drink wine the night before a race (sometimes beer). I don’t carb load. In fact, as I’ve gotten older, I find that I do much better on a meal with protein. I’ll eat fish, pizza, whatever. I think all this stuff is voodoo. It’s a mental game.
That’s why I said if your mind is there, your body knows what to do. We’ve done this so.many.times now I feel like I could do almost anything and finish a race…:-) Thanks Wendy!
I usually wind down the drinking the week before a race and have none the night before, but I do think one glass if I’ve been hydrating through the week is ok…. I think I didn’t enjoy nyc marathon because I am a morning runner and I woke up at 4 A.M. and didn’t run until almost 11 and it threw off my pre-run eating routine … haven’t tried a night run yet!
Running big events like that can definitely throw you off. I think NYC did a good job of having food, drinks, Gatorade, etc in the village but if you’re not used to eating what they have, or eating at all, it can definitely throw you off!
I do a sort of carb-load for the marathon only, but not the traditional giant bowl of pasta (ick) or what seems to be the popular definition of it. I just try to eat a few more blander carbs spread out in the days before and maybe cut back a bit on fiber the day before. I can’t imagine stuffing myself with a huge meal the night before a race! That sounds like it would achieve the exact opposite of what people hope.
I definitely stick with bland carbs too but I have eaten fish or even Mexican the night before a race and I’m fine. I also don’t have GI issues when I run so, there’s that. But, like I said, I steer clear of fiber and definitely try not to overeat 🙂
I couldn’t agree more. I have to roll my eyes when people talk about carb loading. They just use it as an excuse to eat crap. I worked with a dietitian during this marathon training cycle and she said people just need to eat well and reduce fiber just like you said! Also, the timing one is laughable because I’ve trained in the summer in the south. I am NOT going for a run at 9am just to simulate race starts (when my marathon will be up north in the fall)
Thank you!! Yes, so much common sense and I have no clue how anyone trains in the south through the summer. It’s insanity, so you need to do whatever it takes just to stay alive 🙂
I agree on all points. It never even occurred to me to train at a different time to simulate a night race or Ragnar. I think the adrenaline gets us through. I did run into trouble the last time I ran RnR Vegas by walking ALL DAY long on race day, eating a light brunch then nothing else the rest of the day. My lax approach came back to haunt me.
OMG all.the.walking in Vegas kills me too. I think I had 30k steps the day of the half marathon – crazy!!! I do always eat ENOUGH but it’s hard to judge when you start running when the sun goes down 🙁
