[quote="jc22_uk"]It's really difficult not to take her for walks in the woods/fields as a walk around our streets will nowhere near tire her out and she will be hyperactive all night, leading to a very stressful atmosphere in the house.[/quote] Double edged sword here - the more exercise she gets the more she needs to tire her out. You are making her fitter and more athletic so be prepared to go the distance. Physical conditioning does not reduce activity level, it increases it. You will also find that recovery times are shorter and the dog will be more active.
