A marathon is 26.2 miles of repetitive running. Your legs need to be strong, your heart needs to be stronger and you need to be able to go the distance! For the most part you are working your aerobic energy system, which allows you to exercise at a steady pace for a long period of time. Your body will go through extreme contrasts of temperature - very cold in the pre and early stages of the race to very hot once you get going. Much like your body and legs, what you wear needs to be able to go the distance too. Over this enduring period you will feel thirsty; joints, particularly knee caps and ankles will be sore because of the constant pressure from the impact of running on the tarmac for such a long time and chafing can be a major problem.
A marathon outfit needs to stay comfortable throughout the duration of the race. A seamlessly constructed top will reduce friction, lightweight sweat wicking shorts give breathability and double layer, blister resistant socks will stay firmly in place. Make sure trainers are tailored to fit and worn in before the big day.
what should I wear
If your race starts early in the morning and is a cold weather marathon, there is likely to be a lot of hanging around and you can get very cold, make sure you wear an old tracksuit that can be discarded as you start to run and consider a pair of socks or cheap gloves to keep your hands warm which can also be thrown away. Take some big, black bin bags with you so you can stretch out on the ground before the race. Anything you leave behind will be picked up by organized charities. To keep your sugar levels up and give you some oomph and energy pop a stash of jelly babies in your bum bag. No need to carry water bottles as there are plenty of water stops along the way.
