If you take part, or intend to take part in an endurance sport like cycling, marathon, triathlon or cross country skiing, then you need to pay particular attention to consistently fuelling the body with food and liquids.

Endurance athletes, especially those who compete or train in very hot climates are constantly at risk from dehydration. This risk increases the longer an athlete is competing, or if they train or have to compete more than once a day. They also need to eat the right foods so they have enough energy to get through a gruelling event, or a long workout. Some things you will have to take into consideration are:

Fluids

It's important you keep yourself properly hydrated during a training session or competition you should:
  • Replace fluids lost in sweat. If you lose too much fluid and electrolytes (potassium, sodium) through sweating without replacing them you will suffer from dehydration. Sports drinks are a good way to re-hydrate.
  • Take plenty of fluids throughout the day. It's important for the athlete to turn up for a competition or training session hydrated. Start the day off with a sports drink and make sure there is a plentiful supply of water at hand at all times. Use water fountains or water coolers as a trigger for fluid intake.
  • You should hydrate 2-3 hours before competition. Try to take onboard at least 16oz 2 cups of liquid at this time and 10-20 minutes before starting your competition have another 1 cup of liquid at least.
  • It's important you know your sweat rate and how to replace it. Athletes need to know how much they can drink during a competition; this will vary according to the weather and the intensity of the exercise. To know your sweat rate you should measure how much weight (in fluid oz) you lose when competing, plus how much fluid you are consuming; this should equal the amount you need to drink to replace lost fluid.
  • Drink only to replace lost fluids, do not over drink. A lot of inexperienced marathon runners tend to do this, as they run at a slower pace and tend to take on board liquid at every opportunity. This can lead to over hydrating and can become dangerous as sodium levels in the body can drop dangerously low.

Foods

To have the energy needed to get through an event athletes should fuel their body 2-3 hours before the event. Carbohydrates are the fuels for your muscles, and provide the energy that's needed for endurance events. Some people feel they can't run well if their stomach feels full, if that's the case then try having your meal around 5 hours before the event , then top up with a liquid snack or light meal with a couple of hours to go. Here are some pre race fuelling tips:
  • A pre-race meal should consist of high energy foods like- bread, cereals, pastas, rice, fruit and vegetables and lean sources of protein. Around 65-70% of the food on the athlete's plate should be carbohydrates.
  • Attention should also be paid to the meal the evening before a race. It's a good time to stock up on easily digested carbohydrates like potatoes, pasta, rice and fruit juices.
  • The sodium the body loses while competing also needs to be replaced. Anyone competing in an endurance sport shouldn't be following a diet that is low in sodium. Sodium can be replaced by salting your food regularly, eating salt based snacks, like pretzels, nuts or soups.
  • After training or racing it's important to take in carbohydrates as soon as your body will allow, this enhances glycogen replacement. Try having on hand a fruit smoothie, chocolate milk drink, banana, or yoghurt. You can of course have meal of pasta, both solids and liquids are equally as good at refuelling the muscles.
