We begin the day by walking alongside the stretch of the river which hosts the annual Regatta, then up to Hambledon Lock, which was the start of the first ever University Boat Race in 1829. At Aston we have to leave the river for a while, but have a pleasant walk through a deer park. Later, unless Temple Bridge has been repaired by the Environment Agency, we have a detour on the Berkshire side of the river, taking us away from the river and then along the road into Marlow; we then continue on the Bucks side along the river path to Bourne End.
