Looking at Brockham woods from Lansdown Road the jumps are on the RH side, there’s a track in on the right just past the bit where cars park. It’s nothing spectacular mind.
Also some similar jump stuff in the old quarry on the road out of Wick toward Doynton – sensitive though, the police drop by occasionally and have been known to confiscate mx bikes being ridden there.
Very little downhill man made that side of Bath, someone, (ahem) has built some very very near to me but only a short section and it’s so cheeky I can’t really advertise it, sorry. Come out on a Weds night and I’ll show it to you.
Lots more t’other side of Bath, you been to Browns at all? (Above Bathford?), all cheeky and sensitive but can be ridden summer evenings.
Loops from there out toward Conkwell and down to Dundas, including some stuff the trail pixies have built.
