Strava

It'a bit weird around Dorking. Are you purposefully seeking out Leith Hill? You could head south to Newdigate, then across to Capel, Ockley and back to Forest Green without going over the highest hill in the south east.

I'd also hang a left in West Meon and nip down to Warnford, then head up Wheely Down and into Winchester that way. You'd be on the A272 for a bit, but it's downhill and much less contrived than heading up to Alresford and in that way.

Thanks for that Andy, the Leith Hill bit was Strava's auto-routing function, I am assuming that it's based on "the majority of cyclists go this way, so that's what we'll suggest".

The contrived part into Winchester was me- that's a really pretty route in, which I like doing.

I'll change the route around Dorking and repost it- I'd like to do this ride very soon.
