Don't know how many calories to eat.

I'm a 23-year old female, 5' 4", and about 110 pounds. I run 5 days a week for an hour, and bike to get around. I've been wearing a heart rate monitor, and I find that between the hour of running and the hour or so of biking I tend to do in a day, I burn 900-1100 calories. On the weekends I don't run, but I do do the same approximate amount of biking, so I burn probably 300-400 calories those days. What I don't know is what that means in terms of my calorie intake. I don't want to lose weight, but I feel like I'm not eating enough calories and I'm suffering from over training-like symptoms (lack of motivation to run, persistent injuries/pain, inability to get my exercise heart rate up, etc.) Right now I'm eating 17-1800 calories a day.

Anyone have any ideas about the appropriate amount of calories for me? Online calorie calculators only have vague distinctions like "active" and "very active" and "moderately active", and I don't readily trust them.

For your age and activity level, you need 2000-2200 calories per day.

Yes

Thanks! And I assume this is for every day, not just the days that I do formal exercise (running)?
