When running for periods longer than an hour, it is essential to have a fuel plan. A fuel plan helps ensure that you don’t make mistakes as fatigue sets in and keeps you running strongly. You should start the race properly fueled and then take in about 150 calories every 45 minutes until you are done running. Sports gels are a popular option. However, you should try sports gels during your training to find what works for you. Also remember that eating too much before a race can lead to cramping. Try to avoid fatty foods and high protein foods, as these both take longer to digest and use water in the body to break them down.
