Well as a rule of thumb a mile cycling burns between 30-55 calories depending on rider weight, speed etc etc. That means you are burning 1300 - 2300 calories. If you are riding hard, you will burn only carbohydrates. If you ride slower, you will burn progressively more fat (the body does not want to burn fat by the way - it wants to save it for the famine that is coming). Generally a post ride meal should be high in complex carbs. A chicken breast is protein and the salad is zip (except for the dressing which is generally all fat). You need to eat some carbos.

Now, I don't bother with those supplements and stuff. I have had advanced training in biology, biochem etc and I have taught the same at college level. I never found the rationale for them persuasive. You can what you need from ordinary foods that are cheaper and tastier. You can eat just about any complex carbohydrate that you want - bread, mashed potatos, pasta, cereal whatever. But I think if you try that, you will feel much better.

One of the best recovery foods I know is watermelon (wrong time of year now). It is high in electrolytes, has sugars, some complex carbs, vitamins, fiber and those seeds you can spit everywhere.
