I rode a loop from High Salvington to Chanctonbury and back via Cissbury yesterday, all the main bridleways are ok. Theres some gloopy mud and flooding in some places but the core SDW is actually all ok and you can get a good few offroad loops done, it’s one of those times you are actually thankful that someone has done some trail taming and resurfacing!
Being the South Downs though, its a bit slippery on the obvious chalk downhills.
I would forget the singletrack for a few weeks though, I haven’t bothered going anywhere near Stanmer or Whiteways as I know what that will be like. Here’s hoping for some colder weather and a few deep frosts to make some nice hardpack…
Otherwise, get out the roadbike and break out the mudguards 😉
