Daily Carbs

I'm having trouble meeting my daily carbohydrate goal according to MFP. I get plenty of protein (usually way over) and fat, but I don't think I've hit my carbohydrate goal once. I run about 20 miles per week, so I know that I need to eat more carbohydrates, but can't seem to find them in foods that I like. I don't eat wheat or sugar. Any suggestions on carb rich foods that won't send me over my calorie goal (1200)?
