The golden rules to marathon prep
Don’t overload
Many runners are in the mind-set that the more food the better the day before a marathon. Making sure your carbohydrate stores are full and replenished is a must as already covered, but over-eating can make you feel uncomfortably full and add to the sluggishness of the taper. Adding a couple of sports drinks to your day will help increase your carb intake by approx 100-150g without giving you that full, sluggish feeling from oversized bowls of pasta. Be prepared to put on a little bit of weight as for every gram of glycogen that is stored, you also store 3g of water.
Keep it simple
Nutrition should be tailored to your goals and body-type, and some people have a stomach that can tolerate anything. But if you’re unsure about what you should or shouldn’t eat, it’s best to keep things simple. Have your largest meal at lunchtime the day before the race and have something easy in the evening like fish, jacket potato and salad. Avoid anything that is too high in fat as this may cause stomach problems later on. In the morning of the marathon, keep in mind anything that is particularly high in fat and or protein will take longer to digest than carbohydrate.
Hydrate
You don’t need to be surgically attached to your water bottle for 24 hours before the marathon. Be sensible and just make sure you are well hydrated, and your urine is a clear colour. In the morning of the race, have 300-500ml when you wake and have small sips leading up the race to avoid queueing for the portaloo! Think about your environment too, if it is hot you will need to pay even more attention to hydration.
Plan ahead
Looking at what time you want your breakfast (ideally three hours before race) and if you need to bring a snack (banana/energy bar) with you to have an hour before race starts. If you’re staying in a hotel the night before, make sure you phone ahead to see if they will cater for you or simply bring your own provisions! Always keep in mind that sometimes things don’t always go to plan so think of ways you can deal with this if it happens.
