Hi Laura! It sounds like your doing the right things. Extended cardio sessions will help minimise muscle bulk. If you cycle, you could get a turbo trainer to do in the house.
The other side of exercise, especially for weight loss is diet. Don't cut calories too much, but try to keep carbs and sugars low, and fill yourself up with fibre and a good amount of protein. X
