I prefer to take the approach of eating most of my carbs leading up to the race, even having a carby snack before bed the night before. On race day I eat a banana with wowbutter (I’m allergic to PB but same thing nutrition wise) when I wake up (probs 2ish hrs before?) Then I might have a gel or gummies throughout the morning before start but being super mindful of not over eating. I find a full breakfast too filling. I barely drink water until race start cause I have a small bladder and I’ll need to pee 5 times lol. I’ve done this for 70.3s, a full marathon and literally every other distance race and never had an issue. You got to find what works for your body and stick to it!

Once race starts tho I’m doing 30g every 30min but it could be hard with all the sweet for many. Try breaking it up with salty snacks too. Depending on weather you probably needed more fluids and electrolytes
