Swinley has no rocks, a few braking bumps when it’s dry at the end of the summer but thats as bumpy as it get’s.
Aston Hill’s not much further.
Or bite the bullet, load a car up and do a weekend in the Peaks, you could set off (very) early on Saturday, ride all day, stay in a B&B or YHA, ride all Sunday and be back in time for (a late) dinner.
Glentress & Innerlaithen in March, couple of us have few new toys on bikes & local trails round Canterbury dont really cut it to test new shocks etc………Surrey Hills I am told is man made so more looking for harder trails with some rock runs etc to build confidence & test bits out…any suggestions?
You’ll be dissapointed then, GT and Inners are about as man made as they come! The Red’s as smooth as a baby’s backside, the black is rockier in places but I rode it first and still though it was pretty smooth compared to natural trails except where they’ve gone deliberately OTT on stuff like the wormhole
