Leon,
Lots of rain here this morning so the ground is wet, having said that.
The section from Scrubbett’s Farm to Ozleworth Park will have surface mud initially where the trail is used by farm vehicles, after the first gate it’s a rocky surface into the valley and up the other side, it’ll be fine. Don’t over cook it, the bends tighten up, but a great downhill. Look out for the bridle path signs when you get near the house, you go right rather than going through the big arch into the courtyard.
Tyley Bottom is always wet and the trail can be tricky to follow, look out for the removable sections in the wooden fences going down across the first field.
(If I was going that way I’d veer left past Fernley Farm and take the trail SW round Newark Park, good surface although there will be leaves and excellent downhill bouncing over rain bars, but I have the benefit of knowing the area.)
Back to the trail you want to know about, the high points around North Nibley drain well and you’ll be fine up there, pinch points or where horses have been will be a messy but nothing too bad.
The ride has plenty of tarmac sections to clear mud, as long as you have decent clearance between tyres and frame you’ll be fine, it’s only Tyley Bottom that will be boggin, so wear your winter boots.
Weather looking Ok tomorrow so should be OK.
It’s a great area to explore, enjoy it.
Should say, I don’t mind the mud, once I’m out it doesn’t matter, so what I think is OK may differ to others !
