You traded spontaneous plans for scheduled miles. Lazy Sunday mornings for alarm clocks. Twenty weeks of becoming the friend, the partner, the parent who always had to check their training calendar first.
You did it.
You’ve checked the weather app at least 7 times today. The forecast hasn’t changed.
Three days out and the nerves are real: “Should I carbo-load? How much? What if I’m not doing it right?”
Let’s settle it.
What to eat the day before your half marathon
It’s the golden rule for racing: nothing new before or on race day.
So stick to your usual carbs, but add a little more. If you usually eat a big bowl of pho, eat that, with extra rice noodles.
But we’ve got some things to skip today — lots of fiber and fat. That’s the giant kale salad and the burgers and fries.
Unless you eat them before every long run and know they work. The entire goal for your half marathon is no surprises.
When to eat throughout the day
We act like the night-before dinner is A Big Deal. But honestly? Your race-day energy comes from everything you eat the day before.
So instead of saving it all for dinner — eat more of your carbs earlier in the day, when your stomach’s still pretty calm. Have regular meals, and snack every few hours.
Dinner’s just the top-off.
You’ve got race week down.
But the months after — when you’re trying to stay consistent but life keeps happening?
When to eat dinner so you can sleep well
Sleep the night before? Good luck.
“What if I sleep through my alarm? Should I have trained more? f I fall asleep right now, I’ll still get 5 hours.”
Your dinner shouldn’t be one more thing to worry about.
Eat 2-3 hours before bed, so you won’t feel stuffed as you’re trying to sleep.
And if you can’t eat solid food, try liquid calories. Smoothie, sports drink, rice porridge.
The goal: go to bed comfortable, not stuffed.
What to drink the day before your half marathon
Sip water all day. You’re aiming for light yellow pee—not totally clear.
Hot day or heavy sweater? Add some sodium with an electrolyte tablet or sports drink.
Don’t “make up for it” by drinking a gallon at night…you’ll just be up at 2 a.m., feeling sloshy at the start line.
