Here is a route to Ripley for our cafe stop at Pinnocks, at 15 miles, it is a little longer going there than the 'nomal' route, then it is the regular 15 miles back to HCP via bookham and Leatherhead.
Here is a link to the route in Komoot where you can download a gpx and load it into Garmin etc - HCP-WH-Ripley-LHead.
PS tip: early this year another ride leader advised to avoid routes with a 'cross-over', like we have on this route. I used komoot to navigate on 4 Sep 2021 and it sent me right at Effingham when the route as defined goes straight on. Some other navigation apps can be 'over helpful' like this.
