You do not need all that many calories to do your training. With your training, you are talking about 1000-1500 calories depending on whose figures you believe. It is easy to over estimate the number of calories you burn. "I just did a 20 mile bike ride, I will eat a whole pizza, wash it down with a milk shake and finish up with a big sundae!" People often "compensate" for their exercise calorie burn by eating far more calories than they burn and then wonder why they do not lose weight.
So err on the light side.
