“Surface stays good even if it’s wet (plenty of muddy spray though)”
Does that mean that with mudguards it doesnt really matter what time of year we do it ?
Yup – I ride it a few times a year on a tourer with mudguards (though a couple of field crossings, one near Southwater and one just south of Patridge Green can put you off cycling for life if it’s been wet for a while).
Bax Castle can be hard to spot from the Downs link; work out its rough location, then watch for where the trail goes under a road bridge – the gate is maybe 100ft past the bridge on your left (heading south). Cat and Canary at Henfield is much easier – you go up a short rise into a car park, pub’s on your left!
As others have said, it’s most very flat and not likely to excite experienced riders. Can get quite a few walkers at weekends and in the mornings too.
