its super easy. Your gran could do it. Worth stopping at the darkstar brewery – they do cheap beer in milk cartons. The american pale ale is lovely. I swapped out my butchers for DMR motos, glad I did.
Did it on one of my endless-summer-of-youth days when I was 17… er.. that would be 1994.
I road it in a bunch with a Road CC group who’d all got pimp MTBs. I just remember big-ringing it the whole way at about 25 mph, hanging on for grim death, with roost flying up into my red iridium M-Frames and one of the guys’ Tioga Disc Drives rumbling like an army… Then stopping for doughnuts and tea at some cafe…. and pushing on for home. Probably road back to London suburbs afterwards too… Thems were the days, eh.. 8)
The descent off St Martha’s can catch you out as someone seems to be patching it up with random rubble plus it’s quite popular with walkers and horse riders who can be upon you before you realise. The sandy track up to Blackheath can be a proper slog in the dry as traction can be difficult to find. Once you have descended from Blackheath it’s fine from what I remember, although watch out for what appears to be a stream of silage run off before the farm after Chinthurst Hill.
All the above assumes I’ve remembered the route correctly!!
