Brian will almost certainly be able to give you the low down on muddy lane, Old Cleave lane was fairly technical but good when I last rode it but that was before storm Katy hopefully somebody else has ridden it more recently.
192-158 has been gentrified! Almost too easy now but just watch out for the two sink holes which are still there ready to swallow you and your bike! They are obvious coz their red mud stands out from the grey of the rest of the lane surface.
Went past the end of Old Cleave but Trev was carrying an injury so didn't go look.
