Training will be much easier if you have a balanced diet and ensure you have filled up your glycogen stores with carbohydrate rich food prior to riding your bike.
Hydration has an important effect upon performance for all active people. The minimum daily requirement for the body is 1.5 l, but when taking part in any kind of sport, the needs can be much greater. On average you will lose about 1 litre per hour, compensating for this loss is important if you want to maintain your training intensity.
For each ride, the glycogen stores (glycogen is the form carbohydrate takes when stored in the muscle) need to be filled up to provide energy, delay fatigue and prevent exhaustion. To build up your stores in the first place, a diet focussed on carbohydrates rather than fat is preferable. Pasta, bread, potatoes and rice are all examples of carbohydrate-rich food.
Muscular fatigue, characterised by aching legs is a feature of cycling at all levels, especially when riding over rolling terrain. For this reason it is important to ensure sufficient protein within your diet. Highly nutritious protein sources include milk products, lean meat or legumes.
Vitamins and minerals are also important in maintaining and repairing the body; fresh fruit and vegetables offer a rich source of these essential nutrients for your body.
