Ridgeway or SDW this Friday?

We planned to ride the South Downs Way on Friday but it looks like the settled weather is over.  Here in Dorking we had a long shower yesterday and it looks like there are more showers forecast for the coming days.

I always read the SDW chalky sections can be lethal after rain.   Are there any SDW dwellers who could comment on the conditions this week?

Is it more sensible to ride the Ridgeway instead and continue riding from Goring back to Dorking via Swinley, canal and along the NDW?

Looking at photos of the ridgeway on Komoot it appears to be chalky too.

Any comments greatly appreciated.
