Starting at Maidenhead, then doing a loop up to Marlow,Frieth and Turville. A climb up Dolesdon hill, then down to Henley on Thames. Head back to Maidenhead via the back roads through White Waltham.
There are plenty of opportunites to stop at a pub or in Henley if required.
Road Bikes only please- unless you can maintain an average of 15 mph on a hybrid
