9.27 miles door to door direct, various options for getting home; 13, 20 or more miles depending on weather and other commitments. I've cycled every shift apart from a couple when I've been lent GFs car. When I lived closer (3 miles) I rode in (nearly) all weathers on the road bike, when snowy had to walk the ungritted beginning and end bits. We'll see how it goes this winter...
